SUMMARY
After your computer returns (or &quot;wakes up&quot;) 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.



MORE INFORMATION
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
