I have a Dell Inspiron 8100. Yesterday the backlight went out in the middle of my typing. I could still barely see text on the display so I know the problem is with the backlight and not the display driver. After a few minutes it came back on again. But then today, it again just went out while I was typing and has stayed off this time. I am guessing that this might be related to a reddish tone my display had been developing over the past few weeks.

I have been trying to get technical support on this, but am getting a runaround that is getting ridiculous. Boot, reboot, check this button, take out the batteries, and on and on and on and on.

A quick question: Is there a way to turn the backlight on or off manually? I can toggle the display between an  external monitor and the onboard display with Fn-CRT/LCD, but I was wondering if there is any further control.
