Becky has a T21 with the same symptom, and I also suspect a hairline crack in the mainboard. I moved her into a T30 for that reason (the kids always end up two or three generations back), and now hers is about the only T30 around (including clients) which does not need a new backlight (or worse). At least Wi-Fi is well supported - on eCS and XP, the two OSes she uses. > I also got myself a second one, refurbished for just over 200 Euro's and put > the best parts of the two on that one (I had a bad key on the keyboard). > > So I can continue using the T42 for a while longer ... > > That's the best way to go.

I'm not sure which build you are using.
