Chapter 3: Getting To Know The WORKABOUT PRO
Safely Swapping The Main Battery
36 WORKABOUT PRO Hand-Held Computer With Windows Mobile 6 Classic & Professional User Manual
The Suspend Threshold feature allows you to determine the battery capacity at
which the hand-held will be shut down. If left at the default value, Maximum
Operating Time, the unit will run until the battery is completely empty; the RAM is
only backed up for a short period of time. If you choose Maximum Backup Time, the
hand-held shuts off with more energy left in the battery so RAM can be backed up
for a longer period of time.
(Refer to “Suspend Threshold” on page 125 for details about reserving battery
power for data backup purposes.)
3.2.3.1 Safely Swapping The Main Battery
There are a few steps you need to take to ensure that no data is lost during a battery
swap. First, you need to make certain that the backup battery is holding at least 80%
of its charge capacity. This information is displayed in the Battery tab.
• Tap on Start>Settings>System tab and then tap on the Power icon.
Check the Backup battery gas gauge to determine the battery charge remaining.
If the backup battery charge capacity is less than 80%:
• Insert the WORKABOUT PRO in a docking station or cradle to top up the
power supply before removing the main battery from the unit.
Important: Before opening the battery cover on your WORKABOUT PRO to
remove the battery, you must turn off the hand-held. If the battery
cover is opened while the hand-held is still powered on, the unit
may reboot.
3.2.4 Charging The Battery
Batteries shipped from the factory are charged to approximately 40% of capacity.
They must be fully charged prior to use.
Keep in mind also that, along with the main battery, the WORKABOUT PRO is
equipped with an internal, backup battery that preserves data stored on the unit
while the main battery is swapped.
Important: The backup battery is trickle charged from the main battery. To
maximize battery life, avoid excessive discharging and recharging
of the backup battery by keeping the main battery fully charged.
