Dark Screen
Posted: Sat Jan 24, 2009 1:20 pm
My prob seems to be a variation on other screen probs mentioned elsewhere, and I hope someone can help.
I have a T60 with an XGA screen, running XP with SP2. The machine is still under warranty with about eight months to go. It has worked fine until a few days ago when the screen went what I thought was blank but in fact is very dark: I can just make out an image there but it’s so dark as to be unreadable.
I can restore the laptop screen image to the usual level by Fn+F7 or by suspending it (Fn+F4) and reawakening it but it will only last about ten seconds or so before it goes very dark again. However with the mains supply is disconnected the screen stays on OK.
The laptop screen starts with a red tinge, which I thought might be indicative of backlight or inverter problem but why should it be OK on battery but not on mains? The power setting is for 7/7 for both battery and mains.
Grateful for any help on this one. Invoking the warranty will deprive me of the machine so a home fix would be best. Meanwhile I am using a separate screen which is fine but not a very portable solution.
