16.5.4 Battery Pack Calibration
The battery pack contains a micro controller that monitors the battery pack characteristics and
maintains an internal “fuel gauge”. The internal fuel gauge may lose some accuracy after many
cycles of partial discharge and charge. Should this happen, the fuel gauge can be calibrated with
the following procedure:
z
To calibrate the battery pack fuel gauge:
1. Fully charge the battery pack.
2. Fully discharge the battery pack at a steady rate.
IMPORTANT:
The battery must be completely discharged! Operate the diagnostic tool until it shuts down by itself
due to a lack of power. Continue operating the tool when the “low battery” warning displays, do not
begin charging until after the tool has automatically shut down.
3. Fully charge the battery pack.
NOTE:
i
It is not recommended to perform the calibration procedure more than once within 30 days.
The optional Smart Battery Charger automatically cycles the battery pack to calibrate it.
16.6 System Restore
The diagnostic tool contains Snap-on System Restore software that returns the tool to original
factory condition following a catastrophic failure. Use the procedure below to restore the system if
your diagnostic tool does not start the Windows operating system, or if the hard disk drive or other
system files have become corrupted.
IMPORTANT:
All data on the hard disk drive C is erased during a system restore. If at all possible, make a back
up copy of any personal or saved data before proceeding.
It is highly recommended that the diagnostic tool be connected to an AC power source when
performing a system recovery. If AC power is not available, make sure the internal battery pack is
fully charged.
z
To restore the system software:
1. With the diagnostic tool turned off, connect an external keyboard to the USB jack on top of the
diagnostic tool.
2. Select and hold the
Left ALT
key on the keyboard, then press the
Power
button.
A dialog box warning that all data on drive C will be deleted and replaced with original factory
data displays.
3. Select
OK
to proceed with the restore, or
Cancel
to abort.
The system restore begins and the time remaining until completion displays if OK is selected.
The operation typically takes from 10 to 20 minutes.
