    Cool 8.04 Laptop Battery Issues

    Hi all,

    After downloading and burning the 8.04 ISO released today I quickly ran the LiveCD to see what's new So far, so good. Although there's a lot of new good stuff in it, there's one problem which may keep me hooked on 7.10: the support of my laptop battery.

    I'm running Ubuntu on a MSI Megabook S271, the battery is identified as model: 'MS-1058'. The problem: Hardy Heron does not recognize the correct state of the battery or its charge level. With no external power connected Hardy Heron reports the battery as being charged, stating it's 0% charged).

    If I boot the LiveCD with 'noacpi acpi=off' it simply boots without the battery indicator (as expected). The problem is that I really like it when the laptop shuts down cleanly when there's only a little battery juice left.

    Does anyone else come across this issue?

    Yes, I am experiencing this exact issue on a Sony VAIO VGN-N385E.

    Hardy does not detect when I am on or off of battery power and instead reports that "Computer is running on AC power" at all times.

    Any suggestions?

    Same behaviour here on my wife's S271 - on AC the battery indicator will alternate between 0% and 100% charging, on battery power the indicator incorrectly states it's still on AC.

    The battery and charge state is correctly identified for my laptop in Hardy.

    Same here, with a Philips Freevents. With 6.06 I used to work w/o battery all the time. Now, I can't take it off or the laptop won't run

    I'm running into the same problem on a Sony VAIO VGN-FZ280E.
    It worked perfectly in Gutsy but on a clean install of Hardy, it doesn't work.

    Thanks to anyone with some advice.

    Re: 8.04 Laptop Battery Issues

    here's a bug report for it: https://bugs.launchpad.net/ubuntu/+s...pi/+bug/218094

    It'd be good if everyone affected could add their details in, so there's more chance of finding a fix. One temporary fix that works is to hibernate and rewake the laptop, and for some reason the battery indicator works after that (on an s271, anyway).

    Smile Re: 8.04 Laptop Battery Issues

    I found the following work-around suggested in the bug report to be working for me

    A workaround that is working for me (so far) is to add msi-laptop to /etc/modprobe.d/blacklist, which will prevent the msi-laptop module being autoloaded.
    One-liner for your terminal:

    sudo echo "blacklist msi-laptop" >> /etc/modprobe.d/blacklist
