have a six month old HP Pavilion DV6500 Entertainment laptop computer. The computer was working fine and when I turned it on I received a black screen with no whiting or cursor displayed. I have turned it on and off, attempted to reboot with the HP Recovery Disk, remove battery and plugged it in to recharge. Nothing seems to be helping. Attempts to contact HP support on the phone stated that I'm ringing outside work hours. I have not installed any software and am not running periferral items.
I remove all the hardware and leave it out for at least time, I did then, leaving it out for one hour and replacing the battery for ex . After replacing the battery the computer started without a problem. but if I leave it 1 day and I stat it after , always is the same probleme please help me
Had the same problem and was none to happy I called the after hours # and they had me shut the computer down unplug it take out the battery pack. while the pack was out they had me hold the power button for thirty seconds. I put the battery back in plugged it to the ac adapter and unbelievably it came back to life!!!!!! I hope this helps others out! They said it had something to to do with static discharge. I don't care what it is I am just so glad it is working again!!
My girlfriend had the same problem, Here what I have done to resolve it...
pressure in the middle was not of any use in our case...
1) Unplug power supply and take out the battery
2) Press and hold power button for about a minute
3) Insert battery and plug in power supply
4) Use to power button...
5) Select start windows normally
6) I strongly suggest to turn off the computer as soon as the windows boot up is complete and allow the battery to recharge.
I don't know if this is a permanent solution or not but it seems to be related to the mother board power management. It seem to stay in a prevent mode once the unit as overheated...
