Chapter 03: Battery Usage and Care
If the computer is left without a power source for long periods of
time, this battery can be exhausted and system information can
be lost. This will not affect any of your data stored on the com-
puter’s hard drive, but rather the settings in the BIOS that tell the
computer how to operate. It is recommended, therefore, that if
you plan to store the computer for a long time you periodically
attach the battery packs, plug in the computer to an external
power source and allow the battery to recharge.
If you receive a BIOS error when booting the system for the
first time after removing it from prolonged storage, it probably
means that the battery’s level got too low and the BIOS settings
were lost. Enter the BIOS and choose to restore the settings to
default. If this does not correct the error, contact your dealer or
visit TabletKiosk’s website at
nd submit a
support request to obtain proper BIOS settings.
Storing a Battery
When storing your computer for an extended period of time, it
is recommended that you remove the battery packs and store
them in a dry, cool location.
Ideally, store a battery with a 50 - 75% charge. Even when not
plugged into the system, over time the batteries will slowly lose
their charge.
For optimal longevity of the battery packs, it is important to
periodically charge them in order to keep their electrons mov-
ing. Even charging the batteries for ten to fifteen minutes every
60 - 90 days should be sufficient to keep the batteries in good
condition.
Since a battery will slowly discharge during prolonged storage,
you should fully charge it before using it again.
