Description of problem:
APM seems not to "see" the battery: it always notifies that the laptop is AC
alimented even when the AC cable is unplugged. Moreover, the battery icon is
always showing an empty status, the tooltip displays "Battery not present" and
the percentage is "N/A" even though the battery is half or even fully charged;
it seems to me that APM doesn't detect the battery somehow.
The daemon apmd actually starts at the system startup and keeps running until
shutdown, but in the system logs there is a message warning that the charge of
the battery is -1%.
I am sure that the battery itself is finely working because other OS detect it
properly, so the problem must be somewhere in APM (perhaps in the APM bios
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Startup Linux RH 8.0 (kernel 2.4.18-17.8.0)
2. Add the APM icon to the taskbar if it's not already present
3. Simply try unplugging and plugging the AC cable and see what the APM frame
reports; also try and check the battery status and charge
I tried to download a newer version of APM, but the most up-to-date rpm pkg
available was the one shipped along with the kernel I have.
On the APM mailing list, other peole reported similar problems with other Dell
laptops (7500)an RH Linux 7.3.
This is an interaction issue between the BIOS and the kernel APM driver.
BIOS problem, not one we can fix
