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.
The battery will start charging as soon as the device is connected to the power supply. In
doing so, the following conditions are important:
● When the device is switched off the charging process takes around 2 hours.
● When the device is switched on, the duration of the charging process depends strongly
on the system load and can lengthen accordingly.
● 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.
● At high ambient temperatures the battery is protected against overheating by reducing the
charging current. The charging process can hereby extend accordingly.
● The battery protects itself at higher ambient temperatures by decreasing the charging
capacity. If the device is operated at lower ambient temperatures again, the charging
capacity of the battery increases again.
If, with a connected power supply, the battery LED 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 in the BIOS. As a precaution, you should remove the battery from
the device 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. Prior to completion of the discharge, when merely a residual charge
is existent, the LED battery in the battery operation lights up red 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.
