Monitor won't come out of hibernation or sleep mode.

In March 2007, I bought a custom-made a1750y series computer from HP. It has an Intel(R) Pentium (D)CPU 3.00 GHZ, 3000 MHZ 2 cores, 2 logical processors running Vista Home Premium. I got a free monitor with it, an HPvs17 LCD model.

Since spring of this year, after one would not use the pc for awhile, it would go to sleep mode and wouldn't come out of it, even on reboot. It was a miracle if the monitor would come on. So I plugged it up to an older pc, 733 MHZ from HP and after about 10 minutes it came on. But after that it wouldn't come on. So I am now using an older CRT monitor, from a company called Digital that has been since swallowed up by HP some ten years ago. Now this second monitor is doing the same thing.

I am beginning to think it is the video card, an Nvidia GeForce 7300LE Adapter Ram 64.00 MB that needs changing.

I want to know is there anyone that has had this problem and how was it resolved. Thank you in advance.

Monitor won't come out of hibernation or sleep mode.

Same issue - nVidia graphics card in a Dell Dimension E520. It would have a hard time coming out of sleep mode and then at a point recently, I could no longer get it to come on at all even after rebooting. I ruled out the monitor by connecting it to my laptop and sleep mode was working fine. Dell support had a tip - take out the card and plug monitor into the on-board video card. Worked smoothly. (although I'm back running VGA instead of DVI). I guess the nVidia GeForce card is now a frisbee unless someone has a suggestion for repairing it.

This worked for our situation

I don't know if this works for those that have more than one monitor but this solved our problem.

Vista: Go to: Start - Settings - Control Panel - Personalization - Display Settings - (If it shows two or more monitors, click on the other(s) that are not the default monitor and 'un-check' the box stating "Extend the desktop onto this monitor". Hit apply; hit Ok and reboot the computer.)

XP: Right click on Desktop, choose Properties - Display Properties - Settings - (If it shows two or more monitors, click on the other(s) that are not the default monitor and 'un-check' the box stating "Extend the desktop onto this monitor". Hit apply; hit Ok and reboot the computer.)

This should solve not only the sleep problem but the cursor going off the desktop screen. I don't know why but it worked for us and we only have one monitor. For some reason the computer and graphics card think we have more than one monitor.

Hope this helps!
