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
Thanks for your help.
