Some owners may be because of some special reason, to make their car "idle" time. However, the car can not idle idlers. Long-term suspended vehicles, because of erosion by the air leaving the assembly and organization of the PRESARIO V2000 laptop battery technical condition gradually deteriorated, resulting in the loss of their technical performance. To mitigate such adverse effects, the owner should always suspended in the vehicle for the necessary maintenance work to make it in a good performance status.
1, to prevent metal rusting
Corrosion is mainly water in the air, oxygen and corrosive substances caused by the joint action. Therefore, the long-term suspended for a car, should be kept clean metal surfaces. Parking garage should be kept within the ventilation, the air relative humidity under 70%. The need for timely removal THINKPAD R31 laptop battery vehicle dust, dirt and moisture. Corrosion-prone mechanical parts and surfaces should be coated with oil, grease, or dressing up with oiled paper. For the assembly of the pore on the body should be sealed to prevent air, moisture and dust into the interior.
2, to prevent the aging deterioration of rubber products
Automotive rubber products, such as tires, belts, and Presario CQ60 laptop battery dust cover, etc., often in aging, expansion, or to shape behavior, resulting in performance deterioration, life is short.
Rubber, like aging, mainly due to the rubber polymer are unsaturated hydrocarbons, easily absorb the oxygen in the air oxidation of vulcanized rubber while there is a certain air permeability, oxygen from the easy access to internal oxidation. Especially direct sunlight, can cause rapid aging of rubber. Rubber products are gasoline, oil stains, it will lead to volume expansion, glial loose, flexible down. To prevent the aging of rubber products, VGP-BPS5 laptop battery should avoid direct sunlight and exposure to mineral oil.
3, to prevent the cotton and linen products, rotten and carpets, are easy to absorb moisture. Especially in wet areas and rainy season, more damp mildew. Therefore, car owners should always check cotton products, timely drying, keep dry.
4, to prevent performance degradation of gasoline antiknock
Gasoline octane number of Inspiron 1501 laptop battery gasoline antiknock performance depends on the level. Long-term suspended cars, gasoline octane components will be as the light loss and decreased colloid content increases, making it antiknock decreases. Therefore, the fuel tank to be tightly closed, and avoid overheating. Gasoline storage, preferably not too long.
5, always check the engine's working condition
At least once a month starting the engine, idle 4 ~ 5min, check the functioning of the engine. If abnormal, the need for timely adjustment, repair.
Also, always check the battery. Battery electrolyte level must be higher than the plate 10 ~ 15mm, should be enough time to add distilled water, should be kept fully charged, when necessary, should the LATITUDE D800 laptop battery.

What needs to be done in winter car check
Xi'an weather is getting cold, cold winter in this how we should care of their car, so they can survive the cold winter? Let me come to you talk about the winter maintenance for the car to do some things to note.
Check the coolant when the temperature dropped dramatically to below zero degrees Celsius, the coolant level and coolant concentration becomes SONY NP-QM91D battery pack particularly important. As the owner, should be in before winter, and the concentration of the coolant liquid level measurement in order to prevent the occurrence of vehicles in the cold winter freeze coolant situation.
Coolant level coolant fluid through the body of the scale measuring jars. Check the coolant levels need only one coolant concentration meter, this meter can measure the concentration of coolant concentration, then, we can understand the scale above the freezing point of coolant.
If the coolant concentration is too low, condensation point higher than the local minimum temperature in winter you need to add the right amount of pure antifreeze to improve coolant concentration; if the coolant level is too low you need to add the appropriate amount of dilution to the appropriate concentration of antifreeze. Wiper cleaning liquid can also use the same FUJIFILM NP-120 battery pack measuring the concentration of the freezing point, the proposed use of industrial alcohol in accordance with the ratio of 2:8 configuration wiper cleaning fluid (two alcohol eight parts water), so you can clean the wiper fluid freezing point drops below zero ten degrees Celsius to 20 degrees Celsius.
Check all exterior lights exterior lights in winter examination is the most easily overlooked. In the rain and snow weather, low visibility, the vehicle exterior lights of other pilots identify the sole basis for your vehicle. Therefore, please check the vehicle external lighting brightness of the bulb is damaged or low, replace the bulbs out of all the bad performance. Headlamps with LED lights set the need to disassemble the lamp housing to replace the Dell Inspiron 700M battery pack LED, the steps is too much trouble, it is recommended to find a professional service personnel.
Check the tire pressure when the temperature decreases, the tire will increase the gas density lead to lower tire pressure. In addition to lower tire pressure will shorten tire life, but in severe impact on traffic safety. The simplest and most economical way is to use your car tires are brand tire pressure maintenance shops free testing, not money but also to ensure traffic safety.
Check tire tread depth: mean icy winter come; icy road can easily result in loss of control. Then in winter, the tire tread pattern on the grip becomes even more important role. Therefore, before the Dell Latitude D600 AC Adapter onset of the winter tire tread depth must be checked. If the tire tread and the tire has been the center of the main drainage wear indicator groove flush, then immediately replace the tire to ensure traffic safety. You can also use dedicated winter tires or add anti-skid chains: Although many have advertised themselves as all-weather tire season tires, but you can use dedicated winter tires improve vehicle in snow and ice more slippery surface and tracking capabilities.
Check the Presario CQ70 battery and the generator will lead to a lower temperature of the battery can only provide a lower starting voltage, low voltage will cause the engine start can not start. If the generator fails the appropriate output voltage can not make the battery does not charge Dell Inspiron 700M AC Adapter, then, is likely to make the vehicle will not start after a flameout.
Fuel system to prevent freezing or blocking: the lower the freezing point of gasoline, in general, not freezing winter temperatures; and diesel may be freezing in the winter. Therefore, in the winter, diesel vehicle owners need to choose the appropriate label according to the local temperature of the diesel in order to prevent solidification of HP Pavilion dv7 ac adapter diesel.
Check the coolant when the temperature dropped dramatically to below zero degrees Celsius, the coolant level and coolant concentration becomes SONY NP-QM91D battery pack particularly important. As the owner, should be in before winter, and the concentration of the coolant liquid level measurement in order to prevent the occurrence of vehicles in the cold winter freeze coolant situation.

Rechargeable battery basics
We really do not know ah battery, it is necessary for everyone to make up classes. NiMH batteries have memory effect, but no significant nickel-cadmium batteries. The most obvious is the memory effect of lithium batteries. Memory effect is not obvious means you can charge several times, and even used on each charge will not impact too much play. Therefore, use nickel-metal hydride batteries, generally can not consider the discharge and direct charge.
Of course, from the perspective of long life, about 30-50 times the charge and discharge, can do a deep discharge, in order to restore to the maximum capacity. AUDIOPHONE said discharge is not as simple, then a small light bulb, until you can not light. This would tend to over-discharge, but damage the battery.
We all know that a nickel-metal hydride HP EliteBook 2530p battery voltage is 1.2V, when fully charged in just more than the actual value, generally between 1.4-1.5V. With use, the voltage will gradually reduce, in general, the use of occasions, when the voltage is below 1V, you basically can not be used, such as WALKMAN, CD DISKMAN, MD, MP3, DC, and so on. You can test "run out of power," the battery voltage is.
However, if the occasion is a low voltage, low current will continue to discharge. We are talking generally refers to the depth of discharge voltage down to 0.85V-0.9V between. By low voltage, low current discharge, to achieve this value, the nickel-metal hydride batteries (including nickel-cadmium) can be restored to the maximum capacity and prolong life. But if it continues to discharge below 0.8V once may result in irreversible damage to the battery, but battery life is affected. This is why the method is not recommended AUDIOPHONE reason, because you can not control the voltage to a certain value will automatically stop. Similarly, nickel-cadmium batteries and nickel-metal hydride batteries are not recommended for the remote control like a small electrical current.
Depth of discharge of the battery better way is to buy the TOSHIBA PA3399U-1BAS battery charger with discharge function or specialized discharger. The easiest way is to use AUDIOPHONE way, but be sure to read the voltage value table is often used, once the danger zone to stop. If it is connected in series, then simply multiplied by the battery voltage is above the number on it.
And then the battery is not about long-term preservation and restoration methods. Note that, because the nickel-cadmium batteries and nickel-metal hydride battery characteristics are different, so different preservation methods leaves. Nickel-cadmium hp laptop batteries is to run out of power to save, so we bought before the new nickel-cadmium battery is basically no electricity, you need to reset their own. In general, use the correct charging method takes about 3-5 times to charge and discharge the battery back to its best. The nickel-metal hydride batteries to long-term preservation, it should be charged to 80% (this we all should be counted), then save. This is why now buy the new nickel-metal hydride batteries came back somewhat because of electricity, because the manufacturers have pre-charge, to prevent the transport cycle time is too long, while the battery is affected. Long-term preservation of the nickel-metal hydride battery, when I run out of power first, then the right way to charge 2-3 times can be restored to the best state. (After dinner, continue! Oh)
Let me say on the issue of IBM ThinkPad T43 battery charging. In fact, the most difficult to master is the correct charge. Points from the charging current to charge, fast charge and trickle charge a difference. From the charging point of view, there is constant current charge and pulse charge the difference. Many people have this problem, what is a good fast charge or slow charge is good.
Then we take a look at what is fast filling and slow filling what is. Battery with a nominal capacity of 1C, the 0.1-0.2C charging current of the slow charge,> 0.2C for quick charge,> 0.8C for ultra-fast charging, <= 0.05C of the trickle charge is . With a 1400MAH Ni-MH batteries, for example, the charge current between the 140MA-280MA is a slow charger, and the same 280MA charging current of a battery is 700MAH is fast charge. Thus, the fast charge or slow charge is a relative concept, and the capacity of the battery itself has great relevance.
Return to the previous question, what is a good fast or slow is good? ! In fact, this is no fixed answer. Many people think that slow is good, that will hurt the fast-charge batteries. What will hurt the battery fast charge? The answer is yes, but not because a lot of people think the "high current charging damage the battery." Large current is at best an accomplice, the real reason is heat, because heat caused by high current. High temperature on battery life have a great impact. So high current is not terrible, headache is how to solve the heat problem.
Here, it is necessary to introduce constant current HP Pavilion DV8000 Battery charging and pulse charging concept. In the slow charge, it is basically all the chargers are constant current charging method used, so that the circuit design is simple, easy to implement. And because the charge current in the slow range, and will not cause the battery overheating. Fast current charge to use the issue, then use the constant current mode, no doubt unable to avoid battery overheating problem, so the constant current method was abandoned. Instead, the pulse mode, can be seen from the waveform, the output charge current is not linear, but the sine wave. Peak, the current maximum, and then immediately into the trough, almost no current. This design is intended to allow the Toshiba battery to have a recovery time, thus reducing the heat generated by high current, battery heat control at an acceptable level. Now see the hundreds of dollars on the market about the rapid charger, basically using this method. And such a voltage charger is also used to determine slope or delta method to determine the method to determine whether the battery is full, once full turn on automatically trickle charge to avoid a large current over time damage the battery. Relatively well-known example is the recommendation of friends who each fresh cow KN5060 charger. The Chargers are in the major electronic markets, which can be between the 65-70 win, work is not very sophisticated, but the results are good, are highly cost-effective products.
Pulse mode to produce fast HP Pavilion dv4 Battery charger is a good solution, but for some abnormal demands, such as 1 hour quick charger, this time to adopt ultra-high speed greater than 1C charging current for charging, pulse method on insufficient. Is now used internationally are basically added depolarization pulse method as the way. Simply put, that is based on the pulse method, when the upper half of a sine wave is completed, insert a short negative voltage of the cosine wave, the current is too large to offset the enormous heat (polarization response) to the battery heat under control. This method is generally only in the more specialized chargers, such as model aircraft used by professional players on the charger used. Such chargers are often used 2C-3C can be done on the battery charge current.
That these methods, from the perspective of battery life, slow constant current charging is undoubtedly the best way to ensure that the APPLE Laptop Battery replacement life. But from the perspective of time is money, fast charger time savings benefits, damage battery life than the loss of about 10% larger. This is why fast chargers are popular.
Finally, talk about the chewing gum batteries. Many MP3 players say the MD player, you do not to use chewing gum batteries, or how the two of us playing time will be so much worse.
This concept is wrong, the battery is the battery of a chewing gum form, the essence is still the nickel-metal hydride batteries. In other words, a gum 1350MAH 1350MAH battery and a battery of Ni-MH playback is the same, no difference. In fact Ni-MH HP ProBook 6540b Battery have been a 1800MAH capacity, far more than chewing gum batteries. Gum battery production, is to do as far as possible the thin Walkman devices, 5 thin battery specifications do not, and 7, the battery capacity and platform size is small, so small in Japan came up with this approach, not because gum battery capacity is particularly great. And chewing gum are also nickel-metal hydride battery in nickel-cadmium and the difference between the early nickel-cadmium batteries, but chewing gum is only 600MAH, not the current nickel-metal hydride battery 750MAH 7 large.
Of course, from the perspective of long life, about 30-50 times the charge and discharge, can do a deep discharge, in order to restore to the maximum capacity. AUDIOPHONE said discharge is not as simple, then a small light bulb, until you can not light. This would tend to over-discharge, but damage the battery.

Maintenance of GFM lead-acid battery
Battery powered system is indispensable equipment, fixed-type valve-regulated (GFM) for lead-acid batteries with no water, no overflow acid, acid fog has been very little room so widely used. Battery life is certain, if not understand the electrical characteristics of the battery, usually pay no attention to maintenance, it will lead to capacity loss and premature failure, once the Sony VGP-BPS9/S battery capacity decline and reach a predetermined discharge time, we can not guarantee the transmission of television programs and even cause major accidents, we must understand the performance of the battery, and can properly use and maintain.
In order to maintain the capacity of lead-acid battery GFM and extend its life, we experience summed up according to the following maintenance methods:
(1) to maintain proper spacing. Oxygen recombination process inside the battery generates more heat, but emit less gas, reducing heat loss, the internal battery temperature is usually high, so the battery should be placed in well-ventilated place, not too closely arranged, between the individual cells should be at least 10 mm spacing.
(2) maintain the appropriate temperature. Temperature, chemical reactions speed up, lead and acid to enhance the interaction, prone to sulfation, reduced service life; temperature is too low, thick sulfuric acid, e-free slow, poor electrode active, the Sony VGP-BPS5 battery capacity decline. 10 ~ 30 ℃ temperature is more appropriate, according to the actual situation can use various means to adjust the temperature.
(3) to keep clean. Weekly wipe the dust on the battery and the rack to keep the battery clean. The accumulation of too much dust, make bad battery connection point, change the battery charge and discharge voltage, prone to failure. Remember when the battery clean dry cloth or brush to use, it is best to use a vacuum cleaner.
(4) inspected once a day. Day time look at the battery, a slightly acidic News smell in the air whether, if slightly acidic odor, is discharged battery acid mist, ventilation should be timely processing; the second depends on whether the deformation of the shape of the battery, CANON BP-522 battery terminals and valve with or without exudate, normally open valve can, if necessary, to replace the battery.
(5) Weekly test voltage. Single-cell battery float voltage is 2.25 V, not less than 2.16 V. Voltage selection is too low, individual battery charge due to insufficient long-term passivation and void float voltage is too high, the gas overflow increased, gas recombination efficiency is low. Batteries are charging voltage is 2.35 V, should not exceed 2.40 V, the charging voltage is too high will cause the charge current is too large, the heat will make the electrolyte temperature, the temperature drop will cause the battery internal resistance, internal stop the decline and increase the charge current, so the cycle will make the battery deformation and cracking. Note: When testing the battery voltage value, the battery must be measured on the two end points, if the other at the test, will have a voltage drop, the test results are not very accurate.
(6) monthly measurement of single Acer travelmate 6000 battery voltage. More likely to use the number of batteries in series the presence of voltage imbalance, voltage is easy to produce long-term imbalances behind the battery, behind the battery if charging is not complete, the discharge in the future will further increase in the depth of discharge, after the charge even further behind. In this way, the more charge and discharge times, the more prominent uneven, resulting in behind the battery is dead. So every single month should be measured battery voltage value of less than 2.2 V battery to conduct an "equalizing charge" to make it back to the fully charged state, in order to avoid the failure of the individual behind the battery.
(7) half-yearly charge and discharge, this has two advantages:
① the capacity of the battery can be tested to assess the capacity of the battery;
② can remove sulfate. Discharge in two ways, one is the direct discharge load (higher load used), which cut off the external power supply, Dell XPS M1210 battery powered directly release the full capacity of 70%; the other is false load discharge
(Using small loads), dummy load using a variable resistor in parallel to the ends of battery, external power supply cut off by the battery-powered, with a small discharge at the beginning of the current, gradually increase the current, do not discharge immediately after unloading under the false load, should wait for full battery and then removed to avoid the high current batteries are charged when the danger of arcing.
(8) Do not discharge when the voltage is lower than the termination voltage. Battery discharge to the termination voltage, the voltage would drop dramatically if we continue to discharge the electricity received little meaningful, but will reduce IBM Thinkpad r30 Battery life, so the voltage drop through the discharge termination voltage to the discharge should be stopped . Different discharge rates, the termination voltage is different, the discharge rate of large lead sulphate generated less, even if the discharge to a very low voltage, the plate will not be damaged, single-cell battery can be discharged to 1.75 V; discharge rate is small significantly increased the amount of lead sulfate, and the active material expansion will cause stress, resulting in bending or plate active material shedding, affecting the battery life, so they requested the termination to take a higher voltage, usually in the 1.80 ~ 1.85 V.
(9) Do not over-discharge. GFM lead-acid batteries used in the cycle, its life depends on depth of discharge. Deeper depth of discharge, PbO2 particles between the combination of more relaxation, ease off, cycle life will be shortened. In 50% depth of discharge, to access the generator for ACER Aspire 7520 Adapter power supply, battery capacity to be restored after the power supply.
(10) Do not mix old and new batteries as much as possible, because in the process of charging the new battery voltage to rise rapidly, likely to cause the old battery charge is not full, always under-voltage condition, this impact battery life.
(11) idle time charging the battery every quarter, because of long idle negative battery will form a thick, difficult to accept the charge of PbSO4 crystals, this phenomenon is known as irreversible sulfate, can cause premature battery failure.
Battery life is generally about 8 years since we stick with the maintenance methods, the company purchased in 1994 by the battery capacity test, is still within the Acer Aspire 5720 adapter design capacity, you can continue to use.
In order to maintain the capacity of lead-acid battery GFM and extend its life, we experience summed up according to the following maintenance methods:
(1) to maintain proper spacing. Oxygen recombination process inside the battery generates more heat, but emit less gas, reducing heat loss, the internal battery temperature is usually high, so the battery should be placed in well-ventilated place, not too closely arranged, between the individual cells should be at least 10 mm spacing.

(3) to keep clean. Weekly wipe the dust on the battery and the rack to keep the battery clean. The accumulation of too much dust, make bad battery connection point, change the battery charge and discharge voltage, prone to failure. Remember when the battery clean dry cloth or brush to use, it is best to use a vacuum cleaner.

(5) Weekly test voltage. Single-cell battery float voltage is 2.25 V, not less than 2.16 V. Voltage selection is too low, individual battery charge due to insufficient long-term passivation and void float voltage is too high, the gas overflow increased, gas recombination efficiency is low. Batteries are charging voltage is 2.35 V, should not exceed 2.40 V, the charging voltage is too high will cause the charge current is too large, the heat will make the electrolyte temperature, the temperature drop will cause the battery internal resistance, internal stop the decline and increase the charge current, so the cycle will make the battery deformation and cracking. Note: When testing the battery voltage value, the battery must be measured on the two end points, if the other at the test, will have a voltage drop, the test results are not very accurate.
(6) monthly measurement of single Acer travelmate 6000 battery voltage. More likely to use the number of batteries in series the presence of voltage imbalance, voltage is easy to produce long-term imbalances behind the battery, behind the battery if charging is not complete, the discharge in the future will further increase in the depth of discharge, after the charge even further behind. In this way, the more charge and discharge times, the more prominent uneven, resulting in behind the battery is dead. So every single month should be measured battery voltage value of less than 2.2 V battery to conduct an "equalizing charge" to make it back to the fully charged state, in order to avoid the failure of the individual behind the battery.
(7) half-yearly charge and discharge, this has two advantages:
① the capacity of the battery can be tested to assess the capacity of the battery;
② can remove sulfate. Discharge in two ways, one is the direct discharge load (higher load used), which cut off the external power supply, Dell XPS M1210 battery powered directly release the full capacity of 70%; the other is false load discharge
(Using small loads), dummy load using a variable resistor in parallel to the ends of battery, external power supply cut off by the battery-powered, with a small discharge at the beginning of the current, gradually increase the current, do not discharge immediately after unloading under the false load, should wait for full battery and then removed to avoid the high current batteries are charged when the danger of arcing.
(8) Do not discharge when the voltage is lower than the termination voltage. Battery discharge to the termination voltage, the voltage would drop dramatically if we continue to discharge the electricity received little meaningful, but will reduce IBM Thinkpad r30 Battery life, so the voltage drop through the discharge termination voltage to the discharge should be stopped . Different discharge rates, the termination voltage is different, the discharge rate of large lead sulphate generated less, even if the discharge to a very low voltage, the plate will not be damaged, single-cell battery can be discharged to 1.75 V; discharge rate is small significantly increased the amount of lead sulfate, and the active material expansion will cause stress, resulting in bending or plate active material shedding, affecting the battery life, so they requested the termination to take a higher voltage, usually in the 1.80 ~ 1.85 V.
(9) Do not over-discharge. GFM lead-acid batteries used in the cycle, its life depends on depth of discharge. Deeper depth of discharge, PbO2 particles between the combination of more relaxation, ease off, cycle life will be shortened. In 50% depth of discharge, to access the generator for ACER Aspire 7520 Adapter power supply, battery capacity to be restored after the power supply.
(10) Do not mix old and new batteries as much as possible, because in the process of charging the new battery voltage to rise rapidly, likely to cause the old battery charge is not full, always under-voltage condition, this impact battery life.
(11) idle time charging the battery every quarter, because of long idle negative battery will form a thick, difficult to accept the charge of PbSO4 crystals, this phenomenon is known as irreversible sulfate, can cause premature battery failure.
Battery life is generally about 8 years since we stick with the maintenance methods, the company purchased in 1994 by the battery capacity test, is still within the Acer Aspire 5720 adapter design capacity, you can continue to use.

4 common laptop battery tips
How to make good use of laptop batteries, how to extend their use of time and the life of the other issues, no doubt troubled by the majority of books in the heart of a problem user, laptop computer battery has a variety of methods and techniques, which we usually need to use more learning and application. Xiaobian gave you some common tips:
First, go to sleep quickly
Temporarily using a HP Pavilion zd8000 Battery laptop computer, to save battery power, remember to monitor, hard drive and system sleep set a standby time - because you do not work without the need to make your laptop is still running at full capacity. We can set the power management program, allowing the system to sleep after a period of time, but shorter or longer will have to wait a few minutes, there is no way to make the notebook computer system immediately enter the sleep state?
The notebook computer system to sleep, a quick and easy way is to simply turn off the display. Press display just little things, you can make the laptop to sleep immediately, effectively conserve battery power. When you need to re-use, simply open the display, the system will automatically return to the state before the operation.
Second, deliberately run out of battery
Regularly run out of battery, in order to ensure a full charge.
Third, the screen-saving mode
Reduce the brightness of the screen. At the same time, although some HP Pavilion dv9700 Battery books are equipped with the keyboard light, but in order to power, the best conditions in the dark only to enjoy it only concern.
TFT screen is the largest notebook computer power components, in order to reduce its use of the battery when the power consumption, notebook computer manufacturers of all kinds of devices, but in general are based on the lower screen brightness, and even off-screen method.
In the part of the notebook computer's power management settings you can customize the brightness of the screen, most laptops can be a particular shortcut keys adjust the screen brightness, generally 6 to 8 level brightness adjustment.
4, set the power saving mode
Desktop using the AC, most people may not be the computer attached great importance to energy-saving features, but need to use batteries to power notebook computers, the use of energy-saving features should be taken seriously. How to design HP Pavilion DV1000 Battery computer hardware more energy-efficient, this is not the user problem to be solved. The user can do is set the computer on the effective use of energy-saving options. And when the wireless receiver when not in use, turn it off.

Fix Computer memory or RAM problems
Many of the common computer problems like the blue screen or slow computer are due to defective computer memory - Random Access Memory (RAM). Some of the problems can be fixed yourself but in a few cases you may have to either replace or upgrade the memory.
How to troubleshoot and fix computer memory problems
1. Most problems are caused by incorrect installation of RAM. The memory modules should be fixed securely in the memory slot. They should be aligned properly with the notches in the slot. The retaining clips should be fitted properly. Sony VGP-BPS8 battery Memory modules inserted backward will cause permanent damage to both the memory module and motherboard.
2. If new memory (RAM modules) have been installed , check if the specifications match that of the RAM currently installed. For some motherboards, only identical memory modules can be installed in adjacent slots of a motherboard.
3. Check the computer manual and installation instructions of the memory being used. If there even a small problem in RAM installation, there could be errors
4. Remove the memory and again reseat it. The problem may be due to loose contact and reseating will solve the problem.
5.Most memory banks have at least 2 slots for fitting memory modules. Try installing the memory module in another slot, it may start working.
6. Try installing some other memory module in the same slot. If the new Sony PCGA-BP2V battery memory module works, the old memory module is defective.
7. Sometimes if the computer power supplies are not outputting enough power, the memory bus may not receive enough power. So check if the power supply is working properly
8. Check if your computer RAM has gold plated modules that link to the slots. Any other metal used on RAM may get corroded by many elements.
9. It is better to have 2 RAM than one. This will improve your computer TOSHIBA PA3384U-1BAS battery performance and they can supplement each other weakness.
10. Clean your RAM and RAM bank slots from dust and other dirt.

How To Make Your Computer Run Faster
Working with a hanging / freezing / slow start up computer can be time consuming as programs/ applications take a long time to starting up and loading. This problem is more pronounced in computers which have been used for 6 or more months.
How to fix it
1.Check the programs running in the background. Most Dell XPS M2010 battery computer users need only a few basic programs but many other programs are loaded as a default by the computer/application manufacturer. Many antivirus programs run in the background and slow down the computer. you need to stop or deactivate them by following these guideline below. go to
Start==>Run==>type "msconfig" ==>and remove all programs which are not often used or in the boot up unnecessarily. You will have to reset the computer. Also go to control panel:::add/remove programs :::and remove all non-essential software. Use LIUtilities.com to check or scan for files or programs that you don't understand there function. some are Dell D6400 battery system files and very necessary for your computer to run.
you can also deactivate antivirus programs by clicking taskbar icons ::: deactivate
2. De-fragment your computer hard drive. Click on the "My Computer" icon on the desktop. (for Windows XP) and run disk cleanup first. Then go to Tools and Dell Vostro 1400 battery Defragment the hard disk drives (HDD) on your computer.
It is advisable to defragment the HDD at least once a week, (It is automatic in Windows Vista). especially if large amounts of data eg video are being downloaded from the internet. Delete all cookies and downloaded files.
3. Ensure that there is sufficient free space on the Dell KM958 battery hard disk (HDD ) where the operating system is loaded. Free space is required as virtual memory. Delete all unwanted files and transfer all large files / folders to other data storage media.
4. You may have a virus, spyware, trojan or adware on your computer. First remove all spyware, adware and virus by running antivirus program or manually deleting them. Most dell inspiron e1505 battery viruses can be cleaned or quarantined by antivirus programs
5. Ensure that the latest device drivers are installed on your computer. The latest device drivers are usually available at both the computer and component camera battery manufacturers website. You can update windows too. If you are not using a particular device, you can disable it too.
6. Add more memory. If your computer does not have sufficient memory or the memory is damaged, your computer will become slow. dell 1691p battery Windows XP needs at least 128 MB RAM, Vista require more than 256 MB RAM and 512 MB RAM is recommended for optimum performance.
7. Reformat hard disk.If none of the above options work, you may have to reformat the hard disk and install the operating system again.
8. Clean your computer from dust and corrosions. concentrate on cleaning RAM,fan and motherboard since dust build up causes the Dell Latitude D505 Battery computer to heat up fast.
