Hibernation Mode

In Hibernation mode, all power shuts off (the computer does not consume any power). The computer saves all system information onto the hard disk before it enters Hibernation mode. Once you turn on the power, the computer restores this information and resumes where you left off upon leaving Hibernation mode.

There is one necessary condition for the computer to enter Hibernation mode:

  • The Hibernation file created by PhDISK must be present and valid. In this situation, there are four ways to enter Hibernation mode:
  • Pressing the Hibernation hot key Fn-F4
  • Allowing the waiting time specified by the S2D Time-out value to elapse without any system activity
  • When a battery low condition occurs and the Battery Low Suspend parameter in Setup is set to [ENABLED].
  • Invoked by the operating system power-saving modes

Note: If the computer beeps but does not enter Hibernation mode after pressing the Hibernation hot key, it means the operating system will not allow the computer to enter the power-saving mode.

To exit Hibernation mode, press the power switch. The computer also resumes from Hibernation mode if the resume timer is set and matched. The computer also resumes via the network if the Wake on LAN Access parameter is enabled.

Warning: Do not change any devices (such as add memory or swap hard disks) when the computer is in Hibernation mode.
