GNOME power management doesn't notice my laptop battery discharge

I can use my laptop for an hour (AC unplugged), and the battery is still at 98% or so, according to the GNOME battery applet.

It's a Toshiba U400-124, with 4 cell (I think) battery, so only lasts about 2-2.5 hours anyway.

The power stats program in GNOME shows my battery charging OK, but then gives weird stats like 'time until charged: 3.6minutes', just after I've plugged it in.

(Suspend and hibernate work fine.)

Has anyone seen a similar thing before? Or can anyone point me in the right direction to see where the problem is?

I have no idea where to start looking.

Thanks.

Chcek if acpi is correctly reading your battery state.

/proc/acpi/battery/BAT1/state shows the remaining capacity nicely falling away, so ACPI works ok.

GNOME power stats and battery applet are still reporting it to be 99.6% fully-charged.

I think it's a GNOME bug somewhere along the line.

The battery monitor applet works fine (it's just the applet from the power management program that doesn't report correct stats), as does batterymon from AUR.

So I'm using the other battery applet, and all is working fine.

Somwhere in gconf you can change gnnome-power-manager schem so it would read % from acpi. I don't remember exactly where this option was...

Re: GNOME power management doesn't notice my laptop battery discharge

Also as a really quick fix for this until you solve the problem (I'm having the same issue) you can right click on the top panel and select 'Add to panel' and select battery charge monitor. For me this added another battery monitor which as far as I can tell is reporting the correct info (something else than 100%).

Good luck and have a nice day.
