Z77 Extreme4 can t wake up . . .

How do you put the PC into Sleep mode? Please tell us what you do to put the PC into Sleep mode.

Does your PC case have a power light that is on when the PC is on? If it does, what does the power light on the PC case do when you are in Sleep mode?

When my PC is in Sleep mode, if I press the power button on the PC case, the PC wakes up, it does not restart or boot again. That tells me that either Sleep is failing on your PC for some reason, or the PC is really not in Sleep mode.

What is the power supply you are using? The power supply must be turned on when using Sleep, since its Standby 5V rail keeps the RAM memory on during Sleep, which is how the PC wakes without booting Windows.

Try running this command from a Command Prompt (Admin), by left clicking your mouse with the mouse pointer in the lower left corner of the screen and selecting Command Prompt (Admin). The command to type in is, powercfg /a

This is what I get from that command:



I have four Sleep states available, Standby (S3) is Windows Sleep.

Notice that I ran another powercfg command, powercfg -lastwake to show how I woke the PC from Sleep. As I said above, I used the power button as we can see here.

It seems like your board is not going into Sleep mode, even though you seem to be starting Sleep correctly from your description.

If you could go into Sleep mode in the past, you should remember that the power light on the PC case would be going on and off, flashing or blinking is the term in English.

If it takes a couple minutes to go into Sleep mode, which is a long time, it should take no longer than about 15 seconds.

If you haven't changed any settings in the BIOS, the default values should allow Sleep.

Since the power light on the PC case is not flashing, you are not going into Sleep mode, the PC is shutting down for some reason. You said you have 6GB of RAM memory, is that right?

Instead of the way you go into Sleep mode, try this. Put the mouse pointer in the lower right corner of the screen. You should see a black bar appear on the right side of the screen with five entries, one of those is Settings. If you click on Settings, you'll get more options, one of them is Power. Click on Power and you should see Sleep as one of the options. Click on Sleep and see what happens.

When you try going into Sleep mode, do you have a lot of things running on the Desktop?

Have you tried doing a virus scan lately?
