I have noticed the problem when running the ubuntu 2.6.8.1 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.
