- Power Management
Your Tablet PC’s system memory typically stores the file on which you are working, open application information, and
any other data required to support operations in progress. When you resume operation from Sleep mode, your Tablet
PC will return to the point where it left off. You must use the Power/Suspend/Resume switch to resume operation, and
there must be an adequate power source available, or your Tablet PC will not resume.
Hibernation Feature
The Hibernation feature saves the contents of your Tablet PC’s system memory to the hard drive as a part of the
Suspend/Resume mode. Hibernation is enabled by default.
Defining Power Button Action
To determine what occurs when the power button is pressed, follow these steps:
1
From the Start menu, select Control Panel, then select the Power Options icon.
2
Select “Choose what the power button does”, then make your selections (Do Nothing, Sleep, Hibernate, or Shut
Down).
Windows Power Management
The Power Options icon located in the Windows Control Panel allows you to configure some of the power
management settings. For example, you can use the Power Options to set the timeout values for turning off the
display and hard disks whether you are running the Tablet PC on battery power or one of the adapters.
