2. Disconnect the AC adapter and power on the tablet. Let the
batteries run down until the system automatically enters the
Suspend/Hybernation mode and shuts down.
3. Reconnect the AC adapter, let the batteries fully charge
(so both battery indicators glow green) and then run the
computer with the external power still connected for at
least a few hours before unplugging and running on battery
power.
The battery packs should now be properly calibrated. If you
find that battery life doesn't correspond to the battery status as
reported by your operating system, repeat steps 2 -3 again.
If after performing a calibration for a second time you still find
you are having a problem with the battery life, you will need to
go into the BIOS and perform a battery calibration.
1. To enter the BIOS, power on or restart your Sahara Slate PC
and press the L2 (Screen Rotation) button as soon as you see
the TabletKiosk logo.
2. Once in the BIOS, use the L3 button to navigate over to the
Advanced menu screen.
3. Use the L4
button to
go down to
the Battery
Calibration
item.
4. Press the R2
button to enter
the Calibration
routine. Make
sure the Sahara
Slate PC is attached to the AC Adapter and that the AC
adapter is plugged into an external power source and then
press any function button (except L1 and R1) to begin the
calibration.
