Lisa can't detect my battery.

Postby Mlyrin on Wed Apr 11, 2012 7:20 pm

So I installed Lisa 64-bit (gnome) on my laptop (acer ASPIRE 5553G) and it can't find my battery for some reason or an other. I'm fully updated too. The battery itself is a 6-cell lithium ion battery.

Though, the battery itself is still functional when I unplug, i can't see how much power is left because the power indicator won't show up over this "missing battery" issue. I'd like to fix this since I like to carry my laptop around and also because I can't measure the time before it runs out of juice since it varies a lot.

Thanks in advance for any help

Please paste the output after executing the following command in terminal?
Code: Select all
cat /sys/class/power_supply/BAT1/uevent

if there is no such file. Use
Code: Select all
cat /sys/class/power_supply/BAT0/uevent

dom@dom-Aspire-5553 ~ $ cat /sys/class/power_supply/BAT1/uevent
cat: /sys/class/power_supply/BAT1/uevent: No such file or directory
dom@dom-Aspire-5553 ~ $ cat /sys/class/power_supply/BAT0/uevent
cat: /sys/class/power_supply/BAT0/uevent: No such file or directory
dom@dom-Aspire-5553 ~ $

I note in DMESG I have this line:

[Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored


So I suspect this is a BIOS problem.

Mine is a V1.08 dated 04/27/2010

I will update it to V1.23 and repost.

Post upgrade the BIOS still reports same error.

However the default panel battery monitor now works :-)

Nothing else changed just a BIOS upgrade to V1.23 and there were no chnages between the initial BIOS setup and the new one... didn't look like any new options either.

I consider this fixed for now...
