- Power Management
• Selecting “Sleep” after clicking [Start] then clicking the small arrow at the bottom right of the
window.
• Timing out from lack of activity.
• Allowing the battery to reach the Dead Battery Warning condition.
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.
n
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.
n
DISABLING THE POWER/SUSPEND/RESUME SWITCH PREVENTS IT FROM BEING USED TO PUT THE
T
ABLET PC INTO SLEEP OR HIBERNATION (SAVE-TO-DISK) MODE. THE BUTTON RESUME FUNCTION
CANNOT BE DISABLED.
n
THE SLEEP OR HIBERNATION MODE SHOULD NOT BE USED WITH CERTAIN EXPRESSCARDS. CHECK
YOUR EXPRESSCARD DOCUMENTATION FOR MORE INFORMATION. WHEN EXPRESSCARDS OR
EXTERNAL DEVICES ARE IN USE, HIBERNATION MODE CANNOT RETURN TO THE EXACT STATE PRIOR TO
SUSPENSION, BECAUSE ALL OF THE PERIPHERAL DEVICES WILL BE RE-INITIALIZED WHEN THE SYSTEM
RESTARTS.
n
IF YOUR TABLET PC IS ACTIVELY ACCESSING INFORMATION WHEN YOU ENTER THE SLEEP OR HIBER-
NATION 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.
T
HE 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.
