computer turns on in the middle of the night

[LRossi]

I purchased a brand new hp all in one about 2 weeks ago.  In the middle of the night, NOT connected to the internet, my sign computer turns on and my sign in screen prompts me to open.  It will stay like that for hours until I get up and turn it off.  Why is this doing this and can I stop it?  I don't want to burn my screen out.

Welcome to the Forum.

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

Here are some general tips and comments - hopefully something here will help!

If the computer is Shut Down, that is turned OFF, it should not turn itself on

UNLESS

it is booting itself because it has "Wake-on-Lan" capability.

If the system is connected a Wake-on-Lan home NAS server network, that server may be kicking it awake - to do backups, perhaps.  If you do not know what that is, then you don't have 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.

IMO:

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. 

There aren't any good reasons for a new computer to turn itself on after being powered OFF. 

In fact, you might UNPLUG it until then - at least at night!

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

• When backups are scheduled to start (if you are running software that does this)
• When system scans are scheduled to run (Anti-spyware software like Norton or Avast that protects your computer)
• If the dog kicks the mouse - or the cat... or a little mouse ... Anything that moves the (computer) mouse might wake up a sleeping computer.  Turn off the mouse, or put it in a drawer.

What to do:

You can set the system (in the power settings) to turn itself back off after a few minutes.

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.

It's probably Windows 7, maybe it's similar to:

Control Panel --> Power Options --> Change Power Settings

Select how you want the computer to behave and select "Save Changes"

Hope this helps and Good Luck!

Never had this problem until installed windows 10. Now in sleep or hibernate come down in morning and the pc is on.

Had same problem with laptop which turned on in night while on charge and got VERY HOT. This has ruined the battery.

Why does windows 10 behave so differently to windows 7. I regret installing windows 10 which has caused me no end of trouble. I have left it too late to revert using windows.old.
