PC Wakes up randomly from Hibernation ¬_¬

[Samst0r]

Hey,

I usually use hibernation instead of turning my PC off but it seems that my computer doesn't like being hibernated and will randomly turn it self on. It sometimes turns itself on straight away and sometimes after a minute or two. Can someone help me stop this from happening as it is really annoying

Cheers,

Sam.

What type of system is it? (Either the full model if it's a brand-name machine, or the mainboard model.) What peripherals do you have plugged in?

The BIOS setup may have options which you need to change, to disable particular devices from being able to wake it up out of suspend modes. You should be able to muddle through the settings and find them in the Power Management section.

Are you sure it's hibernation and not standby?

Hibernation is FULL power OFF.

Actually hibernation still allows for the mainboard to have standby power supplied to it, which is ATX soft-off. It's the same mode that would allow a PC to turn on from a wake-on-lan card, as well as other PCI or USB devices. ATX mainboards don't really turn OFF unless you disconnect the power.

Right however the PC would be turning on by itself if they turned it off regularly too.

The neat thing about hibernation is you can put a pc into hibernation, take it apart and ship all the parts at different times to someone, have it reassembled and when it's turned on it will be in the exact state it was before hibernated. Of course as long as the hard drives aren't tortured too badly by the courier.

Right,

I checked the bios and all the wake on ____ features are off,

I have a home made pc spec:

Fatal1ty AN8 SLi
AMD 64 3500+ (Winchester)
2 Sata HD's
Gforce 6600 GT
Audigy 2 ZS

Peripherals:

Canon mp830 printer scanner
Mouse bluetooth hub
Wacom A5 Tablet

really? learn something new everyday!

Yeah I just hibernate my PC whenever I have to move, and my laptop is always just hibernated when I'm done with it. It's really great now that it's stable and universally supported.

I would say try unplugging some devices before you hit the hibernate button. Start with the Wacom (I assume that it's USB) and see what happens. Since that's an input device, it's more likely than say the printer to be causing an issue, though the mouse could be as well, or a problem with the Bluetooth device.

 

[Samst0r]

Ok i'll try that...

Could it be a specific service or peice of software thats running thats waking my computer up?

 

[Lord Evermore]

Once it's hibernating, or even in suspend-to-ram, no software is active, so nothing in the OS can have anything to do with the system waking up.

You could also try just resetting the BIOS (jumpers or pull the battery) and then put the settings back to what you need. Screwy BIOS setup can cause weird problems.

 

[Samst0r]

Ok well before I tried unplugging anything i just tried stopping the Task Scheduler service and setting it to manual and it didn't seem to wake up. Is there somewhere that scheduled tasks hide other than the scheduled tasks folder in the control panel?

Sam

 

[Lord Evermore]

That's just weird.

its a ghost...

 

[Samst0r]

Ok, apparently thats only a temporary fix and it woke up in the night -.-
Ok i'm trying what you said now.

Cheers,

Sam.

Hey again,

I've now tried unplugging all the peripherals connected to my computer and that didn't fix it.

I have also tried restoring the bios to defaults.

I'll try installing new drivers for my motherboard and try actually taking the ethernet cable out from my computer even though its disabled in the bios.

Sam

 

[Samst0r]

Right it seems that installing the NVFirewall has fixed the problem which seems a little on the random side.

Cheers for the help,

Sam

Sounds like Wake on LAN was being set on. I have seen cases where the driver would override the BIOS setting on a suspend/sleep state. Since installing a Firewall 'fixed' it, I suspect it was the NIC (modems, keyboard, USB, and serial ports can support it too). It may be a custom setting in the NIC drivers' advanced settings (Intel drivers did this where 3Com would not, but that was 5 years ago). It could also just be erroneously waking with traffic. BUT, if it was waking validly (15 packets sent to it with its MAC address in it), chances are someone was doing it on purpose. For piece of mind, validate your latest AV scan with current signatures.

For everyone else reading this thread... In your experience, have ISPs been forwarding WuOL packets? The original spec had it as a broadcast (and the router would then need to forward it) and the .1 update had the ability to forward them to a specific subnet (AMD's original tool had that feature greyed out.) I would suspect it would be some joker in the same subnet if it were in intentional WuOL to an unprotected set.
