Just finished building my first computer. Got it together and everything works great except for one thing, the computer will not go to sleep and stay asleep. I choose the sleep option and the signal to the monitor shuts off then the computer fans and everything blink off for a split second then it wakes back up. I've tried disabling the "wake computer" options on everything in the device manager and still no luck. I've tried disconnecting the LAN cable, shuting off my wireless mouse and keyboard nothing works. I've selected the S3 and S1 options in bios and still no luck. I've been trying to fix this for 3 days now. I'm open to any ideas on the matter. Thanks.
Have you gone into the control pannel , hardware and sound , power options and created your own custom power plan? Whe you do so there is a link you can click on to change advance power settings and a window pops up and you have to go through all those options one by one to make your selections and see if anything is turned on for wake from sleep.
I mean really, honestly, you may not WANT the computer to go to sleep.
And although this seems like the sleep is a good idea, it's many times not.
Adjust the power settings to prevent the computer from shutting off devices (like the mouse and keyboard) to "save power." Turn off the power saver mode.
There is an issue where the computer turns off the mouse and keyboard to save power. However, after the mouse and keyboard have shut off, they will not awaken unless the computer is restarted.
Since the mouse and keyboard will not function (saving power), the computer does not see your input from the mouse, and will not awaken.
I tried making a custom power plan but it still didn't help. Computer still sleeps for a second not even long enough for the case fans to spin down, then turns right back on.
The video driver is from the disk but says it's up to date. Also when I run powercfg -lastwake under the command prompt it used to come up with USB hub but now it doesn't come up with anything. Any ideas??
