Dell Latitude XPi P120D

This is perhaps the worst Pentium 120 laptop ever made - it has no sound card. There were some Pentiums without one, but those are all mostly 75 and maybe 90MHz machines. It's also DSTN of course. The eventual goal is to source a TFT display for it, as it is working fine. This unit has one issue - the display contast control refuses to work until it's been running for a few minutes. I know this isn't a capacitor issue as it isn't a "fade in" as it runs, it just doesn't respond at all until suddenly it does. No clue why that is.
