Hi there.
I'm running windows 7 on a HP pavilion dv5-1095eo. So, onto my problem:
After filling my computer with loads of crap over the last year, the screen started to be completely black after rebooting the system. No startup messages or HP logo nor anything else, just black. But besides that, the startup runs perfectly. However, after closing down the lid/screen and letting the computer go into sleeping mode and then turning the screen up again the picture miraculously comes back again. I ran my computer like this for 2-3 months until I yesterday decided to format my computer and install a new version of windows 7. Suddenly the picture decided to never come back on my laptop screen, and now I have to run it via my TV through HDMI. Or more accurately, twice today, after starting up from sleeping mode the picture has come back on the laptop screen, but this was quite random since I've rebooted it maybe 20-25 times today.
I have installed all the latest drivers for my graphics card and everything else, including BIOS, but the screen doesn't seem to wanna turn on, even though the screen itself seems to be working fine.
Does anyone recognize this problem, and if so, can you help a desperate fool?!
Thank you in advance

I would suggest turning off anything having to do with power saving/hibernation. In XP it's in the Control Panel>Power Saving...not sure Win7. It would appear that your graphics card is working since you can get a picture HDMI.

Thanx for your reply, but I don't think the problem lies there. (sleeping mode has even been the saviour for me).. However, I'm thinking the problem is in the communication of the computer with the monitor. The screen is clearly fine, there are no signs of loose wires or any other hardware failures, it seems to be that the monitor cannot be identified.
The question is, at what level is this a problem? All the diagnostic tools available in windows 7 say that no problem exists with the screen.
Furthermore, the screen ONLY starts working after going into sleeping mode and waking it up again (however not even this happens more than one in twenty attempts).
Gaah, I wish I understood where the problem lies, since everything points to it being a software issue.
