Yeah a large variety of devices can be set to wake up the computer on modern computers other than the power button. The keyboard, mouse, USB, serial, parallel, modem, network card, lid switch, real time clock, and any interrupts when it is in S1 sleep mode. S3/S4/soft off has fewer devices.

S1 sleep shuts off the CPU.
S3 sleep shuts off everything except the power management, RAM and wakeup devices.
S4 is hibernate. Very similar to soft off. Either S4 or soft off may be used when the operating system hibernates.
Most of those wakeup devices can wake the computer from soft off too.

The BIOS and windows drivers have settings for ACPI wakeup devices.

That's what I did also when my computer turned on by itself.

Check hibernations not enabled and check your 'wake on' settings in the BIOS

I'd second this for the OP. I often simply hibernate my lappy on the usual occasion that I need to turn it off. No sense in wasting the electricity or CPU lifetime if it's not doing anything. As a result, it may wake itself up time-to-time for a scheduled backup or for Patch Tuesday business. The first few times this caught me by surprise; but that's more my fault.  Smiley

Some programs don't deal well with how Windows does the sleeping thing

I quit doing that years ago. My computers are now either on or off.
My laptop is either:
- On
- Rebooting {updates, or back from a crash}
- On the road moving to a different WiFi connection

I propably need to reinstall windows.

And add a firewall and virus protection.

I always have antivirus + firewall.
mostlikely this is not virus/hacker related.


Ive heard that putting computer in sleep mode is bad for it?

Ive been putting my computer in sleep mode for a year now, it has SSD so it should boot fast from poweroff to poweron aswell

there are even some that you can set to turn on when a special msg is received by the network card.

Disabling "Wake over network card" gets rid of this as Oldminer said.

Some bios let you set things like pressing the spacebar or double clicking to turn on, there are even some that you can set to turn on when a special msg is received by the network card.

I think my pc was twice in sleep mode which I put it in.

first time the pc was in sleep mode it suddenly turned on booted bios and into windows, at the log in screen the administrator of the pc had disappeared only my user log in was available(I have no password on either my user or administrator).


The second time same thing pc is mostlikely in sleep mode unless the PC can turn itself on from power off.

Suddenly the Bios boots up loads windows, this time there is my user login and administrator.
This is kind of freaky stuff.

I propably need to reinstall windows.
