battery status stops updating after boot
Posted by HWilton on Thu 17 May 2007 at 09:13
There's still a funny issue, with my HP laptop nx6310's acpi :
The battery status stops updating ; which mean the status is accurate just after boot, but wouldnt change later.
The funny part is that if I physically remove the battery, and put it back a few seconds later - the problem is solved for the next reboot (battery status is accurate, and updated) - but that only last until I power off...
Same as that old bug :

I start to think that might be an issue wit HP laptop (serie nc/nx) acpi management ?

After, hours and hours of troubleshooting - Here are the facts :
1. when pmu is corrupted the symptoms are :
o boot startup sequence is slower (the f9/f10 keys arent responding)
o the battery status is accurate just after boot, but wont update afterward
2. the way to reset the pmu are :
o booting from a LiveCD Ubuntu 7.04
o physically removing the battery
o waiting until the battery is entirely depleted - so the laptop will shutdown violently
So my conclusion would be that the pmu gets corrupted after a shutdown from a kernel 2.6.18 (cos when i bypass that shutdown procedure (see 2.) - the next time the pmu is fine) - but since i couldnt find any settings or misconfigurations, or where an instruction, or whatever command would be the culprit, I just installed the Linux Kernel 2.6.20 and now - everything seems to be running fine now.
