HP ze5300 laptop with XP. I did a disk check. When I came back after it was done, the screen was completely black (I thought was black). I tried re-booting, and the screen remains black. However, I know the unit does work, since I accessed it through a remote program on my desktop pc, and the laptop works fine--can see everything from my desktop, but still cannot see anything on the laptop screen/monitor.

I have since noted that the display is actually on, but extremely dark or dim so that I can barely make out what is on the screen.

New twist. I kept the laptop power on. Came back to it about 45 minutes later, and the screen is completely visible, as though nothing was wrong. I re-booted. Still ok. I have no idea if I did anything to cause it to dim or reappear. But this disappearance and reappearance has occurred 2x. Is there something about to die on this unit?

Many laptops when they're running on batteries will turn the monitor off as soon as they possibly can. Many also don't run at full brightness and in some scenarios can end up so dark under certain lighting conditions as to be unusable, especially again on battery power.

More than likely you do not have a good connection on the backlight for the screen. A poor connection would cause low voltage problem causing the backlight to barely turn on. It could also be tha backlight is failing and soon will not work at all.

Is a failing backlight a repairable component? If so, is the cost of repair in excess of or close to the cost of replacing the unit with a comparable laptop?

Also, I have had the laptop operating non-stop today for the last 6 hours without any problems. Does that in any way affect your opinions?

Your thoughts are greatly appreciated. Thanks.

I am just making susgestions based on my experiences. I doubt the backlight is failing but i did not want to rule it out. The bad connection should be easily repaired unless a wire has almost completely borken and is just barely touching for a connection. Sometimes this is repairable and sometimes it means a backlight replacement.
