Calibrating a Battery Pack
When to Calibrate
Calibrate an in-use battery pack whenever battery charge displays
seem inaccurate or whenever the battery pack has not been used
for one month or more. It should not be necessary to calibrate any
battery pack, even if it is heavily used, more than once a month. It
is not necessary to calibrate a new battery pack before first use.
How to Calibrate
Calibration requires three steps:
■ “Charging the Battery Pack”
■ “Discharging the Battery Pack”
■ “Recharging the Battery Pack”
To initiate an unattended calibration in an optional Battery
Charger or Multibattery Charger, follow the instructions included
with the charger.
To calibrate a battery pack manually, follow the instructions in
the following sections.
Charging the Battery Pack
You can charge the battery pack while the tablet PC is on or off,
but the battery pack will charge faster while the tablet PC is off.
To charge the battery pack:
1. Insert the battery pack into the tablet PC.
