Hey my mate has given me his T40 to look at, when you start the laptop after a while the screen will go black before you even get past the xp loading screen. Once I was able to able to load the diagnostic test and tested the system board everything passed. Any ideas?

Will last known god config, or safe mode work? Was or is SP3 on it?

Does not get that far most of the time. I also dont think it is xp, it went black screen even when running the diagnostic before xp had even loaded

Probably the back light or the inverter for it. Shine a bright light at the black screen and if you look carefully you should be able to see the display.
Also have you tried plugging in an external screen?

have tried external screen. If it was the inverter would I see anything at startup?
