I own a laptop(HP Pavilion DV7) with Windows 7 installed for already half a year.
Usually when I finish my work I do not turn machine off - closing is enough to get is into "Sleep" state.

Generally it's okay for me, but recent several days laptop was turning on in night spontaneously, while I was sleeping.

  • I haven't installed any app with "turn-on by schedule on when_dooes_pc_wants"-like features.
  • Checked if there are some "Wake-On-Lan"-like settings in BIOS, haven't found ones.
  • The power-cable is always plugged-in.

Does someone have any suggestions regarding that?

p.s. laptop is placed right near by bed, so when it turns-on on night - it is quite annoying and a bit scary. I think it's trolling me, please help to stop it :)

Thanks.

Check device drivers in Device Manager, see if any are set to "allow this device to wake computer", disable them.

In addition to moab's answer, you can usually find out which device was responsible for waking the computer as follows:

  • Open a command prompt: Hit the windows key, type "cmd", and press enter.
  • In the command prompt, type "powercfg /lastwake"

Using /lastwake is not perfect, but you can usually tell if it's an USB device or a network card that's waking the computer. If the device was woken up by one of the network cards, the issue is often that Wake On LAN is enabled but not requiring a magic packet.
