So I’ve been running Windows 7 since late beta and am using the 7100 build Release Candidate on my production (main) computer. The system has been flawless, has working quickly, with little to no issues save one: power management.
For some reason, when I switched to Windows 7, my power management options didn’t seem to work; specifically the sleep option. Since installing Windows 7, the computer would sleep but when I tried to bring it out of sleep (by tapping the space bar), the monitor power button color would shift from orange (sleeping) to green (active video signal) but nothing would appear on screen. No prompt, no image, nothing. Frustrated, I looked around, searching the Internet for a fix but besides updating the BIOS, and a host of third party applications, nothing worked. When waking from sleep, I would be forced to reboot the system. At least that was until earlier today.
I was delving into the advanced functions for Windows 7 Power Management and found an obscure setting which resolved the wake-up-but-not-really problem.
Go to Control Panel, then Power Options and Change plan settings on whatever energy plan you’re using (balanced, power, etc.). That will bring up another window.
Now click on Change advanced power settings which will bring up the following window:
First, click on the Change settings that are currently unavailable and then change Require a password on wakeup setting from the default setting Yes to No. Click OK and your problems should be fixed. Let me know if it helps.
