I have a HP NX9105 and I have recently replaced the screen as the old one got cracked. The new screen works perfectly after the computer has booted up into windows (when the mouse cursor first appears, the screen lights up). When the old screen was on and you first switched the laptop on, the word Compaq appeared in red and then the windows xp startup screen would appear with the little animated bar at the bottom. Since I put the new screen in, no compaq screen or windows startup screen but once the mouse cursor appears everything works bloody perfectly. It's not a major problem but if I want to change anything in the bios or go into safe mode etc I have to attatch an extrenal monitor. Anyone know why this might be?? Could it be because it's not an original compaq screen? Thanks if you can help!
