Description of problem:
I have an IBM iSeries 1300 1171-NM1 ThinkPad which I have Linux on. While using
it, I noticed that my battery life was weird. It would go from 16% to 3%
immediately. I decided to watch it and see if it was a problem with my battery
or my apmd components. I saw that it got to 0% and it took 30 minutes after it
hit 0% (while playing sound, so it wasn't just idle) to die. I am using
RedHat's i686 2.4.9-13 version of the Linux kernel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. watch "cat /proc/apm"
2. watch the %age. It's not accurate. .
Actual Results: It'll hit 0% and still stay alive
Expected Results: It should accurately describe the %age available.
/proc/apm is maintained by the kernel, not by apmd.
Reassigning there, but it is much more likely that this is a BIOS bug.
The info comes DIRECTLY from the bios.... the kernel is just the messenger
Since this info doesn't come from linux but from the bios, it's "NOTOURBUG".
However bugzilla doesn't know that, the closest is "NOTABUG".
If you do not agree with this diagnoses please reopen the bug.
