    Standby / Hibernation issue

    Hi,

    i have been using the Standby / Hibernation for one year with no problems on both Vista and Xp.

    But now, when i put the PC to Standby or Hibernation it powers on from itself after undefined time ( from 1 to 5 hours ).

    I do not use WOL or somthing like that.

    Do you know anything about this problem? If yes, please tell me.


    Thanks in advance.

    How can it power on when in Hibernation? That makes no sense.
    As for standby, watch out for drivers that can cancel standby and/or applications.
    Also try searching knowledge base articles on Microsoft Support.

    It's possible, actually.
    (this option will hibernate the computer and will turn it on at the specified time)

    Elysia did not think it was possible for a computer to resume itself from hibernation at a specified time.

    I don't know what might be causing your issue. Perhaps do as Elysia suggested and search Microsoft's website.

    trace what software or drivers you installed recently. Particularly drivers are known to interfere with these modes. I would wager resident software (antivirus, personal firewalls, graphics cards control panels, et al) also have the potential to affect them.

    Also check your bios settings for wake up on lan

    At least my computer totally shuts down on hibernation and saves the memory on the hard drive. And standby on my machine shuts down the processor and the hard drive, leaving motherboard and RAM working. To recover from standby I have to press the power on button.

    I really don't see how a computer could start working by itself when it is shut down (hibernated). Standby works differently on different machines though.

    This is exactly what I'm confused about.
    Hibernation means saving ram to disk, saving the state of Windows and shutting down the computer.
    Next time you start the computer, it will be exactly as you left it (which is why I also love Hibernation - not to mention it's faster than a normal bootup!).
    But since the computer is OFF, there's just no way for it to start again (unless you have some resident chip in the motherboard that starts it after a while, but it's unlikely).

    From what I heard modern computers only shut themselves down in software (unless you switch the power off at the back). I dont know what part exactly handles the management when its switched off, maybe the PSU or motherboard?

    AFAIK the only thing the computer does when shut down is recharging the motherboard battery. Processor is definately shut down.

    Although not relevant to the issue, when the computer is off, power is still supplied to the motherboard, so some things such as USB ports still works. But the CPU is OFF, along with the rest of the hardware.

    A google search for "auto power on" will reveal a host of software built for scheduled resume operations from stand-by and hibernation modes. So, there's a little more to it.

    I don't know the details how it works. But I would put my money (not much) on the mainboard.

    At least on my machine USB ports are dead when the computer is shut down (actually even on standby).

    For me, it's the opposite.

    When those programs cannot turn my computer on from normal shutdown, it cannot do it for hibernation, because when I turn my computer on after hibernation I get the normal boot menu. Maybe it works on machines where hibernate doesn't really turn the computer off.
