Tablet backlight shutting off with certain programs

I have the electrovaya scribbler sc2100 that I just pawned off ebay a week ago.

First time I had this issue was when I was playing a video with MPC, and the backlight would shut off everytime I play the video for a few seconds. I press the power button to make the system go into standby, and i power back on, and the backlight is fine again. I stopped playing the video and the backlight did not shut off for several days.

Then one time when using photoshop cs4, the backlight kept shutting off again. And once again while trying to visit a site that used shockwave(isketch).
It seems to shut off with more CPU intensive processes?

Any ideas what is going wrong?

edit:
Alright, I've been testing this some more with unreal tournament to hope to shed some light on the nature of this issue.

- this does not happen when the tablet is plugged in with AC power
- the tablet is significantly slower with AC power plugged in(seems like the opposite of what should be happening). I get 60fps running on battery power(can't turn off vsync), and 20fps with the ac plugged in.

This could have been bundled with your other question or vis versa. Since your having so many problems its either time to use the warenty, if any, or replace the unit all together.

Wish I had warranty.. it's 5yrs old though.
The hardware seems fine? I'm hoping this is software related since it seems correlated to software.

reinstall the OS or use recovery whichever it has available. i'll take my paypal payment now thanks lol

doesnt it have power settings you can change to never shut it off on battery mode?.
My next guess would be a battery problem, could be at the end of its life and charging a bad battery on AC is why its slowing the system down. sudden boost of CPU power draw on a bad battery and perhaps causing the screen backlight to shut off.

how does it act if you remove the battery and put it on just AC? if it doesnt slow down then battery is likely cause, if it still slows down then hard to say, could still be that or something else but if all else fails reinstall the OS and back everything up. might not hurt to put a voltage meter on that AC output and make sure the AC/DC converter is working ok with proper power output, but that doesnt explain the backlight issue less theres multiple problems at work

out of ideas so good luck
