Since 2.6.9 kernel I have experienced problems with the battery state
on my Compaq Presario 2104EA laptop. I have noticed the problem when
running the ubuntu 188.8.131.52 kernel, which I believe is patched with a
recent acpi release, and the gentoo-dev-sources 2.6.9. I just
installed a 2.4.26 kernel, and have found that it works perfectly.
The problems are quite complicated. Essentially when i boot with the
power adapter plugged in, acpid will give me the correct reading of
the battery. When there is a CHANGE of AC adapter state (i.e. i unplug
it), acpid does not give me the correct battery status, which remains
at the level which it was at. The same problem happens if I start the
computer without AC power, and plug it in: in this case the battery
status does not go down as it should.
Can anyone help me with this? I am fairly certain that it is a bug,
and the results when I tested it with the 2.4 kernel have convinced me
that this is not a hardware problem.
I thought that I would email this list before contacting the acpi maintainer.
I would be happy to provide any more information, and I hope i've been clear.
Many thanks in advance for your help.
