This information reported by lshw comes from the BIOS and the battery, and it is complete nonsense! I expect that the BIOS is providing similarly bogus information about the charge state. But I don't know why the ACPI battery driver would have changed the way it interprets this. > See thread here for example: > http://ubuntuforums.org/showthread.php?t=1543467&page=2 This could be a similar problem, though no-one seems to specifically say that this bug was introduced between Ubuntu 9.10 and 10.04 (i.e. between Linux 2.6.31 and 2.6.32). > and > https://bugs.launchpad.net/linux/+bug/218094 [...] That bug report is specifically about the msi-laptop driver, and was made in 2008.
