Update: This machine has been usable since this happened in Win32 (dual boot) as long as I don't do graphics work or play DVDs or games or anything. Today, I booted back into FreeBSD to sync some files with my Gentoo machine (which I have been using as my primary desktop since this happened to my FreeBSD laptop) and on a whim I pushed VERY firmly on the space of plastic between the power button and my display. Miraculously, the screen garble ceased! About 5 minutes later it came back, so I repeated the proceedure and it's fine again. Gee, if my video chip was toast, I don't think pushing on the plastic would help. It looks like I've got a loose connector somewhere. Anyone have any ideas on what to check? I already tried reseating the LCD connector... and the garbled output appears on external CRTs too... -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
