battery may need to be replaced

January 27, 2012 at 03:04:24
Specs: Windows 7
Upon start up my pc gives me a message that says my battery may need to be replaced. I charge my battery until it is full, when I turn it off and turn it back on 50% is gone. This has never happened before as my pc is relatively new. Please help. Thanks.

You may save the day by simply recalibrating the battery or updating the BIOS of your machine.

For recalibration; fully charge the battery. Remove external power. Run your machine untill battery runs out. Recharge the battery. This may recalibrate the battery.

For BIOS update; visit the manufacturer's web support and check if there is a BIOS update addressing the issue.

Hope the above helps.

In the battery industry it is called a Deep Cycle and should be done periodically.

You have to be a little bit crazy to keep you from going insane.

Recalibrating (deep cycling) for Lithum Ion batteries does nothing for the battery life. All it does is recalibrate the battery meter to the battery.

I am not trying to extend battery life. You cannot extend anything if it is not there. What I am trying to do is to determine if battery is real dead. If battery is not calibrated, Windows may think that the battery is depleting and try to switch to hibernation earlier, which makes people think that the battery is lasting a short time.

Win 7 also had problems initially with charging and companies overcame the problem with BIOS updates. This is why I also suggested BIOS update if one is available.

To nicy: I am sorry I do not use a laptop on battery power. I use it as a desktop with the charger connected all the time. Therefore, I cannot answer your question. All I am trying to do is to tell you what I think I know about computers. Please see HP Customer Care for drivers and BIOS update that may help resolve the issue.
