Laptop battery cause error and freeze Windows XP

One question look like my problem : ID 22929868. But didnt help me.

ID Event =  Source : ACPIEC  - Category : None - Event ID : 3
\device\ACPIEC: The embedded controller (EC) hardware returned data when none was request.
This may indicated that the BIOS is incorrectly trying to access the EC without synchronizong with the OS. The data is being ignored.

*** This error happens only when the battery is plug in and it is not empty. ***
(In other way, if I take off the battery or if the battery is 0% of charge, then using only AC).
When it happens, there is a process named SYSTEM (user System) that take 25-45% of CPU time that prevent other device to answer Windows. Touchpad and keyboard don't answer. If I plug USB input device, they work but I can't close Windows normally, because thre is no answer form "Rundll32.exe" (power option properties).

Things already done:
- New Windows installation (XP Home Sp2)
- BIOS is update to the newest version possible (3A25 to 3A27 didnt solve anything)
- No problems when I boot in safe mode (even with network) probably because the power option isn't load!
- It looks like the problem happens 10 months ago and it was solves by changing the battery but I think there might be something with the board or something else that cause this and makes a wrong battery re
charge.  

Thanks for your help.

So after changing the battery does the problems goes away for the last 10 months ? If yes, then that is definitely the battery problems ...... As a suggestion, turn off the power while during the night / while you are not using the notebook, this will make the battery life become longer since it is not being used for 24 hours ........

Thanks, yes this is short terme solution probably (hope that we solve it again and that 1 year warantly will be valide). The laptop isnt mine and don't know yet "how" the battery  is use.
LIke I told, I though that maybe someone knows if I shoould check the power supply, CPU or the board.
But you are only confirming what I expect so if no one else has something else, the case could be close.

Thanks again.

I was searching on internet for info on almost the identical problem on the very same model acer aspire 3000,  & having read your post & tried your suggestion of removing the battery I can confirm that the laptop now works absolutely perfectly WITHOUT the battery in it.

Thanks very much for your help & I hope this helps some other poor sod!
