Using the Tablet PC
If you are replacing the battery, wait until system operation is suspended and the power
indicator is flashing before you remove the battery. Failure to do so could result in loss of
your unsaved data.
(Note: If the
Resume On LAN
function is enabled in the
BIOS Setup
, you should not remove
the battery unless the system has been shut down. When Resume ON LAN is enabled, the
buffer battery is disabled in order to optimise battery life.)
!
The power indicator either flashes (Suspend-to-RAM) or is not displayed (Hibernate) when
system operation is suspended, depending on how your system is configured. At this point,
programs that were running are stopped, active data is saved, and the system enters one
of two different low-power modes, or suspend modes, as explained in the following
paragraphs
Refer to the "Resuming operation" section in this chapter to resume system operation. Also, note the
following with regard to suspending system operation:
● You can remove the battery while the system is in Suspend-to-RAM or Hibernate mode in order
to install a charged battery. To prevent losing unsaved data, wait until system operation has
been suspended before you remove the battery.
Note: After removing the battery, you have approximately five minutes to replace it with a new
battery or to plug in a power supply before the buffer battery is depleted.
● Your system may be configured to suspend operation automatically after a period of inactivity.
● If the battery charge drops to a Low Battery warning level while the system is running, the
system will beep periodically. If this happens, suspend system operation, shut down the
system, or connect an external power source, such as the mains adapter, to the Tablet PC.
● If the battery charge drops to a critically low level while the system is running, the system is
forced into a pre-selected mode (Suspend-to-RAM or Hibernate). If this happens, you must
either install a charged battery, or connect an appropriate external power source such as the
mains adapter before you can resume system operation. If the battery charge drops to a
critically low level while the system is in Suspend-to-RAM mode, the system stays in Suspend-
to-RAM mode until power is restored or totally dissipated.
● The suspend function on the On/Resume/Suspend button may be disabled to prevent
accidental interruption. If this is the case, pressing the On/Resume/Suspend button will not
suspend system operation as described here. (In this case, suspend mode can only be
activated using the system software.)
