Power Management
The Mesa 3 runs on battery power, using a rechargeable, Li-
Ion battery pack. A non-removable, internal battery pack is
an option.
Charging the Battery Pack(s)
For instructions on how to insert and charge the removable
battery pack, refer to Chapter 1, Install the Battery Pack.
For tablets that have both a removable battery pack and
an optional internal battery pack, the intelligent internal
battery charging circuit first charges the battery pack with
the least amount of energy. When this battery pack comes
to the same level as the other battery pack, then both
battery packs are charged at the same time until they are
both fully charged.
Battery packs are charged most efficiently at room
temperature (68°F or 20°C). They will not charge if it is too
hot or too cold.
!
CAUTION: Only use the battery charger that came with your
Mesa 3 tablet. The Mesa 3 requires a 30W or higher power
supply with a 12V output to power the tablet and charge
the batteries at the same time within the specified 4-6 hour
time frame. Anything less will not allow the tablet to operate
as specified.
Battery Status and Management
To find out how much battery life you have left, tap on
the battery icon at the bottom of the desktop screen. The
amount of charge left as a percent and the status of each
battery is shown. The cumulative amount of battery life left
for installed batteries and the approximate amount of time
battery power will last is also shown. The amount of time left
varies depending on what you are doing with the unit.
Battery Life
Battery life on a full charge can be 12 hours or more. This
varies depending on whether or not you also have an
optional internal battery, the applications used, backlight
usage, and radio usage. The optional internal battery adds
5-6 extra hours of battery life.
