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 
kernel module).

Version-Release number of selected component (if applicable):

How reproducible:

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

Additional info:

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
