View Full Version : [ubuntu] Incorrect Battery Level

June 16th, 2010, 10:11 PM
Alright, here's my problem guys. My laptop has a issue with the charger, which sometimes causes it to not charge if I move a certain way, but that's not what causes this issue.

My issue is, the battery meter incorrectly shows me how much time is left on the battery, which causes the laptop to go into hiberate within 30sec of it not charging.

Here is a screenshot of what i'm talking about -- it's clear to see the issue here =P

Also, using Ubuntu 10.04 64-Bit.

Really, what i'm looking for is a way to disable the laptop from shutting down when the battery gets low...

I have the same issue on a netbook version of 10.4 on an Aspire One 532h. (Intel N450). You can reproduce the error quicker by suspending, and resuming. Most of the time, after resuming with a full battery, it will shortly say critical low and shutdown.

BTW, this bug is across a lot of DISTROs, I have it with Meego and the same hardware.

Someone offers a fix in this thread (http://ubuntuforums.org/showthread.php?t=1487918) - be sure to read the whole thread.. it's not an old battery issue as some have brought up.

I have an acer aspire one 532h about three weeks old and it happens to me too. I disabled power manager for a while, but I like having the indicator. I did change the setting so that if the battery gets critically low it will suspend instead of hibernate. Also, is I select suspend or hibernate from the shut down menu it comes back up ok.

For now, when the battery indicator goes red I try to plug in as soon as I can.
