For the past few years, whenever I walk away from my PC for more than 15 minutes or so, I put my machine in sleep mode. This has worked well for me for quite some time. Until last week, when suddenly my monitor stopped "waking up" from such. Instead, it comes back (power button on monitor goes from orange to white) only to say "Monitor going to sleep"and go back to orange. This while the case lights up properly and makes the appropriate sounds it usually makes when running. And when I press the auto-adjust button on the monitor, it will say "no input signal" for both VGA and DVI. (I use VGA).
I've done a whole lot of Google sleuthing, trouble-shooting, and even asked a friend who knows PCs well. The basic conclusion I've come to is, problems waking from sleep mode are common place and wide-spread and have dozens of potential fixes, none of them guarenteed. The range of reasons for my sudden issue could likewise be any number of a dozen or more things. I've heard anything from OS software, drivers, to hardware like power supply, video card, to so many other things in between...
I was just wondering if anyone had any ideas though?
I'm on an HP Pavilion Elite m9500t, with Windows Vista 64-bit SP2.
Monitor is HP w1858 wide LCD monitor on NVidia GeForce 9600 gs.
If anyone has any ideas or needs more system info... let me know. It's become second nature to use sleep mode, and going back to the reboot each time method is... tiresome.
