84 - Lithium ion Battery
Low Battery State
When the battery is running low, a low battery notification message will appear. If you do not respond to
the low battery message, the batteries will continue to discharge until they are too low to operate. When
this happens, your Tablet PC will go into Sleep mode. There is no guarantee that your data will be saved
once the Tablet PC reaches this point.
Dead Battery Suspend mode shows on the Status indicator just like the normal Sleep mode. Once your
Tablet PC goes into Dead Battery Suspend mode you will be unable to resume operation until you provide
a source of power either from an adapter, or a charged battery. Once you have provided power, you will
need to press the Power/Suspend/Resume switch to resume operation.
In the Dead Battery Suspend mode, your data can be maintained for some time, but if a power source is
not provided promptly, the Power indicator will stop flashing and go out, meaning that you have lost the
data that was not stored. Once you provide power, you can continue to use your Tablet PC while an adapter
is charging the battery.
