Panasonic Toughbook PC Laptops usually have
very reliable battery pack. When your unit is plugged-in
but the Power is OFF, you should see an LED light as follows:
RED FLASHING: Means the battery needs replacement.
Orange/Yellow Solid: Means battery is charging.
Solid Green: Means battery is fully charged.
NO Light AT ALL: Means that Battery Pack is missing.
There is also a battery calibration utility on all Panasonic
Toughbook PC's manufactured since 2004. This is a factory
installed software and is only present in factory units.
This software may also be downloaded as a driver from the
Panasonic Toughbook website as follows:
Check also in the bottom right hand corner under
Windows for the battery Icon. This will indicate if
the battery is charging, present or not present,
and under Windows 7+ will indicate if the battery
needs to be replaced or not.
