Keeps Rebooting After Hibernate

Vista Home Premium just boots back up a few minutes after it's been hibernated and sometimes even does so when shut down. There are no error messages and nothing else is left running on the system to prevent hibernate/shut down. Any ideas?
 
I've already tried HP support and they are rather useless. The idea of a BIOS setting was excellent (and something I hadn't thought of) but upon checking I discovered that there are no such settings there. The way it acts, it really seems related to the OS itself but, as I know little about Vista, I am not sure where to look.
 
Does it do it if you disconnect any cables, phone lines, or or wireless which is able to connect to the Internet?

It does seem to be a Wake On event type of problem.

These are XP related but it will give you some clues of how to diagnose your problem in Vista.

Win XP.. Possible to wake on network connection???
thread779-1345731

Have you checked HP for any Bios update available for your machine?

 
All good questions! However, it happens when simply trying to hibernate (or shut down) for the night and there is never anything being disconnected or reconnected. It does have WiFi but it is disabled in order to use a wired connection.

I know XP well and it does seem related to a Wake On type of event but it's difficult to tell as this is the first I've used Vista. I can find nothing with any setting related to a Wake On being enabled! None of the Power settings have it enabled.
 
Do you have Shutdown/Restart problems if you temporarily (or permanently) disable Hibernation?

How to disable Hibernation in Vista SP1.

In the elevated command prompt, type powercfg -h off and press Enter.

To turn it back on -

In the elevated command prompt, type powercfg -h on and press Enter.

Could it be a faulty power down switch?

Does (in normal circumstances) just touching the screen bring it out of Hibernation? Is there any other equipment (or animal) that is vibrating, blowing on, etc. or in any other way interacting with the machine in its' present position?

 
All the info I have found, concern VISTA and W7 having these problems, and that under XP this does not happen...

usual culprit being the "Wake On USB"...

one suggestion, which helped a couple of people, was to set the motherboard jumper for USB power from +5V to +5VSB...

I did not suggest this, due to the fact that you have an all in one PC, and probably with warranty still attached...

It actually did in on shut down before hibernation was ever enabled. I CAN shut it down properly using the power switch so I doubt if it's a hardware issue. It's only when shutting it down from the Start menu that if restarts.

There are very few third-party apps installed and only those that I used in XP which did not have the problem but I suppose it's possible that one of them might be the culprit but I doubt that too as I know of none that would need to keep the system online. Could there be something in the Media Center system that might want too do so? This last thought seems to the most likely now that I think of it.

As for your last question, it does not remain hibernated long enough to know if moving the mouse or touching the screen will awaken it. When it goes to sleep, though, these actions will wake it back up. Vibration is a slight possibility as we do have train tracks behind the house but it does seem to come on right away rather than only when a train is passing so it seems unlikely too. Good ideas all, though!
 
it only needs a small flaw in the mouse, e.g. I've seen mice cause the cursor to move even when no one was touching the mice, not even close to the table... so don't rule that out...

simple test, unplug the mouse and then per keyboard (shortcut e.g. CTRL&ALT& what ever key you assign it too), put it to sleep...

On an HP Touchsmart, the keyboard and mouse are wireless so there is no way to unplug them but the mouse has a power switch and the system comes back on even when the mouse has been shut off.

I am not discounting the possibility of it being a vibration issue but when the system is idle for 20 minutes and goes to sleep, it takes a bit of mouse movement to wake it up and it never wakes up by itself unless it's been manually hibernated or shut down from the Start menu or the keyboard's Sleep button, which is set up to put it into hibernation. Other than this button, I never assigned a keyboard shortcut to hibernate unless it has some default.
 
the keyboard and mouse are wireless
ooopppsss, my fault, only took a quick glance at the picture of the PC... so I totally missed that, otherwise I would not have suggested the removal...

Hmmm... let me recap, and I hope you can confirm, so that I am totally clear on the situation:

When you manually place the PC into sleep, it stays in sleep... only when it idles itself to sleep that it restarts...

Thanks for the opportunity to clarify! No, not quite, in fact, pretty much the opposite except that I am not talking about sleep but rather hibernate. It is my understanding that hibernate and sleep are quite different. I don't use stand by at all so I don't know if that would be a problem or not.

It seems to stay asleep when it goes to sleep on its own regardless of any slight vibration, short of purposely moving the mouse or touching the screen. On its own, it sleeps rather than hibernates so that's not a problem.

However, when hibernated either from the Start menu or Sleep button, or shut down from the Start menu, it comes back on. The Sleep button is set to hibernate, not sleep, so I am not sure if manually putting it to sleep would have the same problem.

One more thing: it seems to take a moment or two before it comes back on.
 
quite correct there, there is a difference between Hibernate and Sleep mode:

Sleep:
Sleep is commonly known as Standby in Windows system or S3 in ACPI. In Sleep mode, the power supply to non-essential and non-critical component is withheld, and most system operation is shutdown and stopped. All data in physical memory (RAM module) is still kept in internal memory, and whole system is place in stand-by mode, which can be woke up and used almost immediately. In Sleep mode, the power load reduce considerably, saving a lot of energy. However, the power must not be cut off, and must be continue to supply to the computer. Once out of power, the system will have to start again just like a newly boot computer just started from power off state.
Hibernate:
Hibernate, or S4 in ACPI, meanwhile will save the data in physical memory to hard disk drive (HDD), and then power off the computer. In Hibernate mode, a file named hiberfil.sys which has the same file size as the amount of system memory will be created on the local disk. When user wants to use the computer again, the computer will boot up and load back the state at the last hibernation. The advantage of Hibernation mode is that no power is wasted for maximum saving of power.
There is also Hybrid Mode
In Hybrid Sleep mode, system saves any open documents and programs to memory and to your hard disk, and then puts your computer into a low-power state as in normal Sleep/Standby state. An advantage of hybrid sleep is that if a power failure occurs, Windows can restore your work from your hard disk. If a power failure such as power outage occurs when your work is saved only to memory (as in Sleep mode), all work is lost.

on to the problem, would you happen to have a SHARED folder and are connected to a network? or have an attached USB drive? if so, then unhook the drive and unshare the folder, for testing...

PS: I just found a thread on CNET, that talks about disabling the Power Settings for WiFi cards and Ethernet Cards, through the Device Manager, and that it helped others with the same problem on their laptops...

Open Device Manager (type Device Manager into the start search box) and modify the properties for the

"Wireless WLAN Mini-Card".

Leave the device enabled, but open its properties, go to the Power Management tab, and uncheck the "Allow the computer to turn off this device to save power" checkbox. The reboot problem should disappear.

Thanks for the information! More good questions but I know of no shared files or folders unless Windows itself shared them when it was installed recently from the factory image. I'll look to be sure. There are no USB devices connected at all.

However, you may have hit the nail on the head with the LAN devices. I know I checked those setting before but apparently I missed the one for the wired LAN adapter since, at the time, it was not being used. It is probably not the checkbox that your quote suggested but the other one that allows the LAN adapter to turn ON the system. I am still testing after unchecking it so will post back when I know more.
 
That was it! On the LAN card's settings was one in the Power Management tab to "Allow device to wake the computer". It was checked and unchecking it seems to have solved the problem. It actually remained hibernated until I turned it back on. I knew the setting was there but I thought I had already checked it!

Thanks everyone for all your help and especially to Ben for finding the solution so quickly!
