I've lost the backlight or the inverter (or maybe more). It's like trying to read a novel by the light of fireworks.
Personally, being a cheap bastard, I hope to pick up a T22 Thinkpad off of eBay for about $200, give or take.
Ya know...depending on how technically handy you are, if it *is* just the inverter and if it's a fairly common model, you can pick the part up off of eBay for usually under thirty bucks.
On the other hand, if it turns out it isn't the inverter, you're out the money.
