Using the Battery

2
The computer comes with a 14.4 Watt-hour, 7.2V, replaceable Lithium-ion
(Li-ion) battery. You must fully charge the main battery before you can use
the computer. When you change the main battery, a backup battery
maintains your status, memory, and real-time clock for at least 10 minutes.
To view the status of the battery
1 Tap Start > Settings > the System tab > Power.
2 Tap ok to exit.
If your computer shuts down because of a low battery condition, your
computer will not operate. The computer shuts down to make sure that
your data is protected. Although the battery protects the data against loss
for several hours, you should connect your computer to a power source
when you first detect a low battery condition.
Note: In addition to protecting data for up to 10 minutes, the internal
backup super capacitor shuts down the computer if the main battery is
removed from the computer. Depending on the processes running, it may
not have adequate power for a graceful shutdown. If so, the computer
performs a cold boot the next time you apply power.
Make sure you put the computer into a suspend (sleep) mode before
you remove the main battery.
If you have at least one device in your 741 or 751 (radio, scanner, or
imager), the battery power fail level is set so that after the system shuts
down in a low battery condition, there is still sufficient charge to allow the
unit to remain configured, keep proper time, and maintain DRAM
(Dynamic Random Access Memory) for at least 72 hours at room
temperature if the main battery remains in the computer.
The configuration and time are lost if:
• The battery discharges beyond the battery power fail level.
