This can be caused due to an error with the Network driver, third party conflicts, and more. But some reports tell us that the Airplane Mode turns on by itself in Windows 10. You can certainly set it to dim and/or turn off the display after a few minutes - even if the computer stays on, the display will be off.Airplane Mode gets a device in such a state where all the wireless connections of the devices go off. You can set the system (in the power settings) to turn itself back off after a few minutes. Turn off the mouse, or put it in a drawer. Anything that moves the (computer) mouse might wake up a sleeping computer. If the dog kicks the mouse - or the cat.When system scans are scheduled to run (Anti-spyware software like Norton or Avast that protects your computer).When backups are scheduled to start (if you are running software that does this).

If the computer is only " Sleeping", that is - not "powered OFF", then it could wake up:

In fact, you might UNPLUG it until then - at least at night! There aren't any good reasons for a new computer to turn itself on after being powered OFF. IF the computer is shut down and it's turning itself on and you cannot control it, I'd call HP and tell them about it. And, no, the internet would not have to be involved, only your home network, so the question is legitimate even if a bit far fetched. If you do not know what that is, then you don't have it. If the system is connected a Wake-on-Lan home NAS server network, that server may be kicking it awake - to do backups, perhaps. It is booting itself because it has "Wake-on-Lan" capability. If the computer is Shut Down, that is turned OFF, it should not turn itself on Here are some general tips and comments - hopefully something here will help!

Well, you need to say what kind of computer you have (exact model) and operating system.
