automatic hibernation

by dmehling Jan 26, 2009 4:38AM PST

I'm trying to figure out an issue with the hibernation setting on my laptop and desktop computers. There appears to be some kind of automatic setting which will put the computers into hibernation after a period of inactivity. I have checked the power settings under the control panel for both computers and I cannot seem to find any setting enabled that would cause this. They are both set to be always on unless of course I choose to hibernate or shut them down. Are there other setting somewhere that would cause this odd behavior?

The only thought that came to mind are complaints about sleep or hibernation failures with wireless mice, keyboard USB sticks. Ring any bells?

Your post is so light on detail my guess may be so far off that it's a dud. Maybe you can try at least the details asked by the RED words and tell who installed that OS.

Return from hibernation sets inactivity timer to five minute
by avm888 Feb 6, 2009 4:23PM PST

After your computer returns (or "wakes up") from hibernation, it may hibernate again after five minutes of inactivity, regardless of the settings you have configured in the Power Options tool in Control Panel. Inactivity is defined as the absence of any user input via keyboard or mouse.

When your computer wakes up from hibernation, its BIOS performs a full boot and clears any wakeup signals that may be active. Therefore, Windows cannot determine why the computer woke up from hibernation. After approximately five minutes of inactivity, Windows hibernates again to avoid situations such as an application waking up the computer and causing the battery to drain when the computer is not being used.

Note
Some events can reset the system idle timer extending the resume to Hibernate. These events include the following. These events are not limited to the following.

* Paging operations
* When Windows Update examines the system state
* Event logging
* Network detection, such as Dynamic Host Configuration Protocol (DHCP) or Automatic Private IP Addressing (APIPA)
* Third-party services, such as an antivirus program
* Scheduled tasks
