Using the Batteries for the First Time
Before using the Tablet PC on battery power for the first time,
the batteries should be fully charged.
On the front of the Sahara
NetSlate are two battery status
indicators just above the Tablet-
Kiosk logo. These indicators
will track the charging status
of the two Lithium-Ion battery
packs located on the back of the
tablet (see the chapter entitled
Touring Your Sahara NetSlate
for the location of the indicators
and battery packs).
Partially discharged batteries will cause the indicators to glow
orange when attached to an external power source. When each
battery is fully charged, its corresponding indicator will turn
green. Be sure that both indicators have turned green before
attempting to run the Sahara NetSlate on battery power for the
first time.
Calibrating the batteries
After using the system for a while, you may find that battery
performance diminishes. This is normal for Lithium-Ion batteries,
however if you see a large drop off in capacity, the batteries may
simply need to be calibrated.
NOTE: This can happen if the Tablet PC is mostly used while connected
in to an external power source. If this is your typical usage model,
you should consider calibrating the batteries every month or two to
maintain optimal capacity.
To calibrate the batteries, follow these steps:
1. Turn the computer off. Connect the AC adapter and let the
batteries fully charge.
