Description of Problem:

pause every few seconds (most noticeable when using the mouse, which just
Run a laptop install on a ThinkPad 240, run X, move the mouse around
Steps to Reproduce:
1. Start X on IBM ThinkPad 240
2. Move mouse around
Mouse stops moving for a moment every few seconds (system stops
System should run smoothly all the time and mouse motion should be smooth.
After some investigation it appeared to be the battery applet which was
causing the problem - increasing the time between updates caused the pauses
to happen less often. Disabling the battery applet fixed the problem
Arjan, could this be kernel related?
Or more likely, a bug in the applet causing it to consume CPU and slow X
down. Most probably not an XFree86 bug.
Bios bug; some biosses take forever to determine batterystatus and the
battery applet then causes evil things ...
After Arjan's comment I checked the BIOS version and found there had been 14
releases since the version I had. I upgraded to the latest version (1.16) and
the applet doesn't appear to cause any degradation in performance now.
