operation:

•  The time set on the resume timer elapses.  

Note:

The computer does not accept any input immediately after it enters sleep mode. Wait a few 

seconds before taking any action to reenter operation mode.

Hibernation mode

In hibernation mode, the following occurs: 

•  The system status, RAM, VRAM, and setup data are stored on the hard disk.

•  The system is powered off.
