Operating Instructions, 12/2018, A5E43198909-AA
Battery operation
The battery (lithium ion) enables mobile use of the device, independently of an external
power supply. It also protects against data loss in the even of a power failure.
As soon as the external power supply is connected, the battery will start charging. In doing
so, the following conditions are important:
●
When the device is switched off the charging process takes around 3 hours.
●
When the device is switched on, the charging process takes between 3 and 6 hours
(depending on the system load).
●
The charging process is terminated as soon as the battery is fully charged.
●
A charged battery will discharge itself during storage (depending on the temperature, and
whether or not it is installed) over a few months. It will then have to be recharged.
●
The battery charging is terminated when the battery is fully charged or if, for example, the
upper temperature limit for charging is exceeded. You can check the battery charge level
in Windows.
When the power supply is connected and the status indicator of the battery lights up green,
the battery is full and will not be charged any further.
Current consumption in battery operation
You can reduce the off-state battery power consumption of your device to the minimum by
disabling the Intel® AMT and USB charging functions in the BIOS. You should remove the
battery from the Field PG if you are planning on not operating the device for several months.
Ideal storage conditions for the battery pack: Ambient temperature of approximately 20 °C
and battery charging state of approximately 50%.
Note
The battery pack may by completely or partially discharged (e.g. due to self-discharge)
during commissioning. Before full discharge, when only a residual charge remains, the
battery status indicator lights up red in battery mode as a warning. End your work and save
your data. There are now only a few minutes battery running time left.
Please note that for a complete disconnection from the mains the mains connector must be
removed.
