Hi!I'm having the problem that my system (running Windows 7 Beta, x64 on a clean harddisk, atthe moment)reboots about 5 seconds afterit has finished hibernating. It always does this, so it's pretty much reproducable.This same issue happened for me when using Vista x64. However I never got this problem when hibernating with Windows XP (32 and 64 bit). When I shutdown my system normally (e.g. without hibernation), it does not reboot, and just powers off as expected.No hardware has been added that should keep it alive. My motherboard is anAsus P5B-E. I disabled all options in the BIOS with regards to "power settings". Without any effect. On Vista I also tried the 'bcdedit' trick, which also had no effect.The hibernate itself works fine, and once the system has rebooted, I'm back where I was again. Does anyone have any idea why this could occur and what I can do to prevent it? I'm not sure if this is the right place to ask, if it isn't, please let me know. I have tried days of searching, and trying, but without any success so far, so I do hope that someone can help me out.Thanks.

Chances are that you have some other driver installed on your system which does not handle resuming from hibernation properly. I am not in front of my Windows 7 machine at the moment, but in orderto troubleshoot this you will need to get a kernel memory dump. On vista you could set this from your startup and recovery options.The next thing you need to do is to download WinDbg and install it so that you can open the kernel memory dump and type!analyze -vwhich may take awhile since it is analyzing the kernel dump. Once that is complete it will have some information on the screen which will have a driver name and an error code.If you need additional help, post that information in a message and someone should be able to help you track the driver which is causing your reboot.

Hi,Thanks for your reply, but as far as I know these kernel dumps are only created when the system actually crashes (e.g. bluescreen)?Also I am not having any problems resuming from hibernation, hibernation itself works fine. And if I turn off my computer by "pulling the plug" after hibernation is complete, and then a few hours later turn it on again, it resumes from the hibernation just fine.So the only problem I seem to be having is that something is telling my system to reboot after hibernation is complete. My hibernation procedure is as follows:1.I select 'Hibernate'2.Screen fades to black3. Windows creates hibernation data, and writes it to disk4. System shuts down. HDD and Power led are off.Then, after 2-5 seconds:5. System starts againAs mentioned before: This problem also occurs in Vista (x64) but not in Windows XP SP1-SP3(x86 & x64).

oki had the same thing as welltry thisturn off the wireless adapter (if you have a wireless adapter switch, turn it off) before you hibernateunplug any or all USB devices (especially wireless mouse/keyboard)then hibernatehope that helps

You mentioned that the machine rebooted after hibernation as opposed to resuming after 5 seconds which is why I expected it to be a driver issue. I misread part of your post in which I thought it resumed and then rebooted as opposed to just resuming right after it was put into hibernation. Rebooting implies power cycling, running the POST and so on which would have implied a pretty catastrophic error thatcould have beendevice driver or hardware related.After reading your reply it is clear we are not dealing with that scenario.Since the issue is that the computer immediately resumes after hibernation then you want to disable the wake up from anything that is not initiated by you. This means that you want to look for a setting to disable USB wake up and/or network wake on LANfrom the BIOS if its possible.Worst case you may have to set jumpers on your motherboard.If this does not work thenyou have to then either go looking to see if there is a BIOS update that helps to resolve this issue or hope asus posted a newer set of drivers to address this issue. I am using a P5E andam not experiencing thosehibernation problems.Hopefully it is just a matter of disabling the wake-up settings for anything other than your keyboard.Good luck

Hi,As said in my initial post, I already checked all BIOS settings, and they are all disabled. Today I stumbled upon a thread on AnandTech where someone discussed the same problem I was experiencing, with the same type of motherboard. He solved his problem by moving all USB wake-up jumpers from +5V to +5VSB. It took me a while to find those jumper on my motherboard, but I am happy to say that after changing all of them to +5VSB, the problem stopped. Now when I hibernate my system, it turns off and stays off.So my problem appears to be solved right now. I still don't know why I did not have these problems on Windows XP, and I can't explain why it works right now either. The only thing I can think of is that Vista/Win7 uses a different sleep mode than Windows XP.

I am not sure whether I should have started anewthread??I have exactly the same problem on an old Soltec SL-85DRV3 motherboard - Hibernate works fine except that the system reboots a few seconds after closing down. Did not occur with XP.

i have the same after 2-5sec its rebootno problems with xp or vista at first in w7i dosnt change bios settings or so on only the problem in w7

We have the same problem. My MB is an Asus P5. I'll try the BIOS settings.

same prob here... asus P6Q Deluxe v2

I have the problem as well. mainboard: Gigabyte P35 DS3r

I was able to solve the problem on my side by doing the following:1. I turned off the setting that enables legacy USB in the BIOS.2. I went to the Windows control panel, then the device manager, then expanded categories for the keyboard and mouse (and others that might involve USB connections, such as human interface devices and USB hubs), right-clicked on each entry, selected properties, then the power management tab if it is present, and unchecked the entry that allowed the device to wake up the PC.For now, I don't see any devices that I use that require these features.Edit: the PC turned on after an hour or so. I'll try to disable the USB selective suspend setting option in advanced power options.

OK, it worked. What I did:1. turned off the legacy USB setting in BIOS2. unchecked the entry that allows the device to wake up the PC in the power management tab in the properties of each keyboard, mouse, and USB device in the device manager (accssed through the control panel)3. disabled the USB selective suspend setting in the advanced power options

Nine times out of ten it's the network adaptor set to wake up computer.

bumped to the same problem. But i'm not having this issue till last week before several windows updates. i cannot change the jumper since my computer is a Laptop (Sony Vaio SR series to be exact). it is ran by Windows 7 Enterprise 64 bits. I already check the bios and Wake-On-Lan is disabled. Any idea?Man may come and Man may go, but I go on forever

Edit: the PC turned on after an hour or so. I'll try to disable the USB selective suspend setting option in advanced power options. for ralfymann: In advanced power settings disable "wakup timers". This wiill stop the box from waking up after about an hour and will stay in hiber4nate indefinately.
