Why cant AC adapter keep the battery charged

January 23, 2011 at 12:03:34
Specs: Windows 7, 512
The battery runs the computer until it starts to beep. The AC does not come on until the computer is is shut off. On restart the AC comes on and charges the battery then the AC goes off. The battery runs until it beeps and the same process is repeated

Have you, or is it possible anyone has
- dropped this laptop ?
- spilled liquid on it ?

If yes, a technician who posted on this site says those things are the most frequent reason that components need to be replaced inside the laptop's case.
...........

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

.....

If there is nothing wrong with your AC adapter or it's connection and the jack in the laptop.......

Laptop main batteries usually work as they should for a year or so, then they begin to rapidly deteriorate. From what I've seen, by two years they cannot be charged to anywhere near their full capacity, and it gets worse after that.
They often develop internal shorts when they are older. If the battery gets HOT rather than just warm after you have attempted to charge it for at least a half hour, or after you have been using the laptop for a while with the AC adapter plugged in, it's definitely internally shorted and you must replace it. Internally shorted batteries getting too hot have been known to cause the laptop to catch on fire.

Tips about battery charging problems on Dell laptops - may apply to other makes.

See the info about the Dell charging problems.

Clean had drive ?

Do you mean ...

- you want to wipe the data off the hard drive so that most people cannot retrieve data from it ?

Or

- you want to clean up by removing un-necessary stuff in an existing operating system installation on the drive ?

You can wipe the data off the hard drive so that most people cannot retrieve data from it, however there are experts that could still get data off of it if they wanted to, and the only way to prevent that is to physically destroy the drive.

Search the web for : securely wipe hard drive

See the link to the info about the Dell charging problems at the end of response one.
Many laptops have a separate board that charges the battery - if his tips don't help, and if your laptop does have such a board, you can probably buy a replacement board for your laptop.
If your laptop does not have a separate board for that, then the only cure is to get a replacement mboard - if your model is not recent you can probably find a working fine used one for a reasonable price - just make sure it has no bios determined passwords.
