[Powertop] Strange Behavior - PowerTOP 2.0 Seg Fault

Hello, I was reading PowerTOP documentation and was curious whether it could help me better manage power on my HP EliteBook 6930p laptop. I am running PowerTOP v.2.0 on openSUSE 12.2 64-bit. After looking at some of my options from the Overview and Stats tabs, I elected to run 'powertop --calibrate' as the docs suggest. PowerTOP did not complete the calibration process; it exited with a seg fault. Now the hardware button for WiFi (small button along the top of the laptop near the screen) flashes constantly. I'm concerned that PowerTOP caused some sort of hardware problem and damaged my laptop. Is there a way for me to check what PowerTOP did to my machine? Is there a way for me to completely revert any changes made by PowerTOP? uname -a Linux 6930p.site 3.4.11-2.16-desktop #1 SMP PREEMPT Wed Sep 26 17:05:00 UTC 2012 (259fc87) x86_64 x86_64 x86_64 GNU/Linux 6930p:~ # powertop --calibrate Starting PowerTOP power estimate calibration Calibrating idle Segmentation fault Any help would be greatly appreciated. -- Chris
