How to charge your laptop battery properly?

How to charge your laptop battery properly? During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.
For early notebook batteries (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.
In fact the lithium batteries has a little memory effect. The lithium battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.
A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had "full" level.
Sometimes WINDOWS show that battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery
So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity . This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

Battery is not charging


If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

When I plug in the adapter to my Dell 1501, the mouse pad doesent work properly. It only works properly when it's unplugged. I did'nt use to have this problem until I bought a new replacement battery and adapter. I tried placing the old ones but still have the same problem now. What can I do to solve this problem. Thanks!


Update the bios
Download from dell.com (use the download via I explore option)
remember to connect the battery and the system and battery should be more than 10 % charged also should be running on mains& ensure ther is no power outage during the bios update process

Unless you took the batteries to a service center, I am dubious about your ability to confirm the main battery is holding a charge. The average lifespan of these kinds of batteries range between 3-5 years and is likely at the end of its lifespan. This would explain the diminishing performance over the last year if there were significant power or power circuit issues, they would likely be observed on AC power as well. This model of laptop requires the battery calibration utility be run in order for the laptop use the battery. In fact, the battery can show a full charge and still not function if the utility and battery have not been properly configured.. . . instructions on HOW TO do this below. If this doesn't FixYa then the battery will need to be replaced (links to replacement sources) www.BatteriesOvernight.com/HP-Batteries,----- OR --- www.new-laptop-battery.com/Compaq/?Compaq-Armada-E500-battery.htm. You will still have to run the configuration utility when you receive your new battery.

How to run config utility: Standby and hibernation must be disabled for the battery to discharge completely and shut off. To use the Battery Calibration utility, first identify whether the battery requires calibration by launching the Power Management applet as described above. On the Battery Calibration tab, all installed batteries will be displayed in the primary list box. Next to each battery name will be an indication of whether calibration is required for that battery. If calibration is necessary, the phrase “Needs Calibration” will be displayed. Select the battery to be calibrated, and click the Start Calibration button. During calibration, the utility will display an icon on the Windows System Tray to indicate that calibration is in progress. Each phase of calibration (charging or discharging) will also be displayed. Calibration is complete when the icon is no longer displayed in the System Tray. Battery calibration requires several hours for completion. If you choose to continue using the computer during the calibration process, it must be connected to AC power. The calibration process must be allowed to finish without interruption. Performing any of the following actions will prematurely terminate calibration:  Clicking the Stop Calibrating button in the Compaq Power tab.  Unplugging AC power from the computer.  Unplugging the calibrating battery. (This action may result in data loss if a second battery is not installed.)  Undocking the computer.  Pressing the power or standby button.  Powering down or suspending the machine by using the Windows menu. IMPORTANT: If the calibration process is interrupted, it cannot be resumed. You must restart the computer and start the process again.
CALIBRATING WITHOUT THE UTILITY To calibrate a battery on computers without the battery calibration utility, complete the following steps: 1. Remove the second battery, if present, so that only the battery needing calibration remains in the computer. 2. Dock the computer or connect the computer to AC power. 3. Turn on the computer. 4. Check the current battery capacity level by positioning the cursor over the battery icon in the system tray. 5. Allow the battery to charge to 100%. You may use the computer, but the recharging process will require more time. 6. Set the system to “drain” mode on the battery conservation settings by pressing Fn+F7, or select Start > Settings > Control Panel > Power (or Compaq Power in Windows NT). 7. Undock the computer or disconnect the computer from AC power. 8. Restart the computer in MS-DOS mode by clicking Start > Shut Down > Restart the Computer in MS-DOS Mode > OK. 9. Allow the computer to discharge until it shuts off. 10. Dock the computer or reconnect AC power. 11. Allow the computer to charge again to 100% as in Step 5.

Sharp MC24 notebook will not charge the battery


The charging element on the mainboard that passes the AC/ to a resistor is out, gone, needs to be replaced and in saying that the mainboard comes with it unfortunitly.
