■
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 BUTTON 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
.
■
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
.
■
IFYOUR 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
.
