@kaia One more thing. Since the ATX time, computers are not really turned off. Even if you press the power button, and the machine goes down, it is not physically turned off. The power is still (remains) on the mainboard circuits. You can still turn the machine on by pressing some keyboard keys, by wake on lan, wake on usb, by timer etc. The real power of is only possible by pulling the power cable out and by removing the battery from the device.
