Insomniac Laptop

How do I prevent my Vista laptop from spontaneously waking up from hibernation?

I have an HP tx1120us laptop running Windows Vista Home Premium. Whenever I put the thing into hibernate mode, it stays off for a few hours, but will then spontaneously "wake up " into sleep mode, and (usually) run down the battery before I return to it. This happens just about every time I put it into hibernate, and I have no idea how long actually stays off, but it seems to be about 3-4 hours.

I know that it is not just the power button being bumped because it does not spontaneously start up after being properly shut down, nor did it have this issue while XP Pro was installed on this system.

Am I stuck having to just shut the thing down? I really like being able to use the Hibernate feature. I also can't just put XP back on the system, because various doohickeys on the laptop (fingerprint reader, remote, touchscreen) are not supported under XP.

There are a few ideas here ranging from wireless mice to automatic updates or a network adapter set to Wake On LAN.

My laptop, a PowerBook, would wake up randomly and, as suggested by dhartung, it was the mouse, though not a wireless one-a standard USB model. I've since upgraded to a wireless Bluetooth mouse and I have turned off "Allow Bluetooth devices to wake up this computer" so it's no longer an issue. So I'd start with a mouse if a have one and then try removing any other USB devices like external drives or printers.

upon looking at my event log, it does appear that its automatic updates that wake up the machine at 3am. This does make me curious, considering (I thought) that hibernation was for all intents and purposes the same as being shut down.

Nevertheless, I am pleased that the problem is now solved, and my laptop can get a full nights rest.
