Battery charge decreases from 100% to 60% when unplugging

Hi, I hope this is the right section to post.

I have a Dell Inspiron 1520 and have just installed openSUSE 12.1 x86_64. When plugging the lap it charges normally, but when unplugging it when it reaches 100%, battery icon immediately reads 60%. It only “fixes” when restarting the system.

Also, if I don’t restart and let it count down from 60%, it does show up the alert message when reaching 15% or less but the battery LED on the lap doesn’t flash orange as it should when it’s running out of charge, which would mean a “bug” or bad reading in openSUSE’s or KDE’s energy managment, or kind of. I confirmed this by switching to Win 7 x64 (I have dual boot), it still had some charge remaining. I have never tried letting the energy reading reach zero though, too risky.

I had this exact problem on openSUSE 11.3 x86_64 with KDE 4.6, but I didn’t have it with its default KDE 4.4.
What’s happening? Can anybody help? Thanks.

My 2 cents: a KDE bug.

I’ve seen this type of problem several years ago, and IIRC it was due to ACPI issues.
When on battery, try comparing with

acpi -b

You may need to install acpi first

I’ve got a Toshiba laptop that has battery monitoring problems every time
I’ve swapped in a new battery. Reports 100% charge while XP reports only
90% or so, reports 10% remaining then does a panic off - things like that.
I usually have to completely discharge the battery then do a full recharge
or two before KDE gets the message and starts reporting the levels somewhere
in the ballpark with correct. Still not perfect but at least it’s usable.

Curious thing I found out: if I unplug the battery seemingly before reaching 100%, say at 98%, the bug doesn’t occur. I have no idea if Gnome has the same issue…
