My computer laptop HP Vista about 2 yrs old was running fine and then it went to the black screen like it does when I am away from it for too long. However, after pressing every button including the power button it will not come back on. Help. It will power off and then when i hit the power on button the lights will come on but it returns to the black screen and stays that WAY. Help!I had a Laptop do this the other day, all lights, no action.
What I had to do (once it was tuned off) was unplug everything from the laptop, remove the battery and try to turn it on like normal to drain all power from it.
Then replace the battery and turn on like normal and Viola! working fine again

Kurtis1. Display Cutoff Switch. By design, I would expect power to the display to be cutoff when the display screen is FOLDED down. This may be accomplished by a "cutoff" switch somewhere along the top back edge of the laptop. Is it possible the switch is "stuck" in the down position?

2. External Monitor. The display output of a laptop may be directed to the built in screen, an external monitor, or both. Is it possible a function key was hit directing the display output to the external monitor port?

3. Did the display screen go "black" as you were watching it?

4. Is anything displayed on the screen as the laptop starts?Ok new problem. It is now trying to start but I get an error saying the FOLLOWING file is missing or corrupt
windows/system32/config/system

It say I can try and rerun start up disk ( which I dont have)

HelpAny idea what caused the "black" screen on your laptop?I am having a very similar problem. It's an HP dv6000 PURCHASED in Jan 07. When I try to power it up, the lights turn on, the fan begins to go, then the fan stops and there are 3 really loud beeps. 1 long followed by 2 SHORT. Can anyone help?Quote from: grant782 on September 15, 2008, 08:25:32 PM
