Computer won't sleep

Question

Iron

The computer is at work, it turns off normally, but when you press the Sleep button or through the “Sleep” menu, the computer enters sleep (turns off), and then turns on after a second. You have to wait until it turns off, press the button. In the morning we turn it on and the system boots normally.

What could be the problem?

Answer 1

Give more space (maybe the swap is growing?)
Mice \ keyboards \ network card can be taken out of sleep

Answer 2

For me (and two other people) in the seventh Windows, it helps in the device manager to remove the daws with the permission to wake up the network card, mouse and keyboard. I suspect it will help you too.

Answer 3

In the BIOS, you can find a list of devices that are allowed / prohibited from waking the computer from hibernation

Answer 4

And take out the network cable, maybe wakeup on lan works.

In Windows 7, this behavior can be observed if it is loaded from an inactive partition. For example, if you have Linux as a second system and boot through older versions of GRUB.
