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

and 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.
