Screen problems with i series 1400 2611-411

[crotalus]

Hello, today I decided to use the old piece again, and it worked for a few hours. Suddenly the screen went black and I just don't know what to do. I updated the bios to the last version available, I tested the external monitor function and it works. Anyone has some idea? Could be that the lcd cable disconnected from the mainboard?

Thank you



Other problems involve not-working fn key and exahust cmos battery...

Plus, I have another question, in the info file for bios upgrades of the 411 and the 412 I read that while in the 412 you can mount win2000, in the 411 you can just mount windows me, is this so?
