LOW BATTERY ALERT
When backup battery drops low, the mobile computer prompts for recharge with a dialog.
And Title Bar
shows an icon.
Backup battery is rechargeable by external power (through power adapter) or main battery
pack.
Low backup battery puts DRAM data in great danger. Always save data from time to time or
keep a fully charged battery at hand for replacement.
Once backup battery drains out completely, the data in DRAM is gone. Any data yet to be
saved is lost!
2.4.4. POWER MANAGEMENT
The mobile computer features “suspension”, a “soft-off” state allowing the mobile computer
to consume less power and quickly to wake up.
The mobile computer auto-enters “suspension” when one of the following happens:
 When placed face-down, which suggests the mobile computer isn’t actively used.
 When battery door isn’t in place.
And it wakes up from the following events:
 Power button or scan key pressed
 WWAN ringing signal
 USB cable plugging
Note the mobile computer is also manually suspensible through Power button. See Suspend
Mobile Computer.
