battery monitor not showing correct number

[Shuai]

I am running KDE and the battery thing on the KDE Tray is not showing the right battery. It does show, when it is plugged in, that it is plugged in. but when I use battery power, it always shows 0% or -1%. Help, please!
Thank you.

By the way I am using fedora core 4 on an acer aspire 5002 with AMD Turion 64 bit.

I've got the same problem with my Acer Aspire 3002lc under Gnome.
Anyone got any suggestions?

Did this stop working when you upgraded the kernel to the latest build 2.6.12-1.1435_FC4 ?

If so, it seems to be having some problems with acpi and reading the battery stats see

I'm currently running 2.6.12-1.1369_FC4, so that bug doesn't really apply to me. But according to this thread: http://forums.fedoraforum.org/showth...stpost&t=62532 the 1447 build might work. I'll install it shortly and let you know how I go.

the battery monitors have always been a bit crap.

on my toshiba satellite it always shows as 51% battery on boot, then later it will show the correct battery remaining and if it's plugged in or not, on kernel < 2.6.11 it didn't even show that!

Update:

Installed 2.6.12-1.1447_FC4.stk16, and have had no change at all. As per a suggestion from another thread regarding my SiS900 ethernet controller, I have to boot with the kernel option acpi=ht in order for me to have LAN access and as with the previous kernel, with this option enabled, the battery meter doesnt work at all. Without the option, it will happily detect if I'm running off AC or battery, but won't give any indication on charge.

FYI, for me its more of a convenience than a nesessity to have a rough charge reading. I barely ever use the system for long with the AC plugged in anyway - pretty much only as I move to a different room.
