View Full Version : [ubuntu] Battery problems

August 31st, 2011, 06:39 PM
Hi all,

I am running Ubuntu 64bit on a Samsung RF411 laptop. I usually run it off A/C power, but I noticed that the battery indicator is wonky: it runs smoothly for a while, then the indicator suddenly plummets and tells me that my battery is almost flat (screenshot provided)

The laptop is barely a couple of months old, so I doubt my battery is spoilt. I do not experience this problem when running win7 on my laptop either. So my question is: is it just a problem with the battery indicator software? Is it under-reporting the battery charge? Or over-reporting it while consuming lots of power?

I read in some other threads about power-guzzling bugs in the Linux kernel that makes battery life significantly shorter compared to running Windows, but couldn't really make head or tail of it. Any help is appreciated.
