hi, i have a compac presario 900 and the display decided to stop displaying. i have no idea on what to do. i'm an ase auto master tech and thought maybe i could take it apart and maybe see something out of the ordinary but it proved almost destructive to try and break her open. what can i do? maybe some one out there know a trick to open her up. if i do, what sould i look for? thanks a bunch.
