43 - 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.
• IF RUNNING YOUR TABLET PC ON BATTERY POWER, BE AWARE THAT THE BATTERY CONTINUES TO DISCHARGE WHILE YOUR TABLET PC IS IN SLEEP
MODE, THOUGH NOT AS QUICKLY AS WHEN FULLY OPERATIONAL.
• DISABLING THE POWER/SUSPEND/RESUME SWITCH PREVENTS IT FROM BEING USED TO PUT THE TABLET PC INTO SLEEP OR HIBERNATION MODE.
T
HE BUTTON RESUME FUNCTION CANNOT BE DISABLED.
• IF YOUR TABLET PC IS ACTIVELY ACCESSING INFORMATION WHEN YOU ENTER THE SLEEP OR HIBERNATION MODE, CHANGES TO OPEN FILES ARE NOT
LOST. THE FILES ARE LEFT OPEN AND MEMORY IS KEPT ACTIVE DURING SLEEP MODE OR THE MEMORY IS TRANSFERRED TO THE INTERNAL HARD
DRIVE DURING HIBERNATION MODE.
• THE MAIN ADVANTAGE OF USING HIBERNATION IS THAT POWER IS NOT REQUIRED TO MAINTAIN YOUR DATA. THIS IS PARTICULARLY IMPORTANT IF
YOU WILL BE LEAVING YOUR TABLET PC IN A SUSPENDED STATE FOR A PROLONGED PERIOD OF TIME. THE DRAWBACK OF USING HIBERNATION MODE
IS THAT IT LENGTHENS THE POWER DOWN AND POWER UP SEQUENCES AND RESETS PERIPHERAL DEVICES.
