Power Management problem - Slacko 5.4

[natgab]

Question regarding power management,

I was watching a movie on TV hooked up ( VGA ) to my Thinkpad X40. The computer keeps dimming after every 30 min or so. The screen dims even while the movie would still play. I am wondering if there is a setting I didn't set. I have the laptop plugged in to the AC, and I set to never sleep and never sleep display. Doesn't seem to be caused by save file, since that only makes the menu appear above the movie ( I am using full screen ) and then dissapears.

I am using VLC on Lxpup 13.01 ( non PAE slacko 5.4 based ).

Can you move this to the Slacko thread? Or delete and I will make a new one.
