When not plugged into a mains socket, the notebook runs on its built-in battery. You
can increase the life of the battery by caring for the battery properly. The average
battery life is around 500 charge/discha rge cycles.
You c an extend the battery life by taking advantage of the available energy saving functions.
Charging, caring for and maintaining the battery
BatteryBattery
The notebook batte ry can only be charged when the ambient temperature is
between 5°C / 41°F and max. 35°C / 95°F.
You can charge the battery by connecting the notebook to the mains adap ter
(see "
Mains adapter connecting", Page 17).
If the ba ttery is running low you will hear a wa rning alarm. If you do not connect the mains adapter
within five minutes of the warning alarm described above, your notebook will automatically switch off.

Windows also has a "Battery status meter" in the taskbar for monitoring th e battery capacity. When
you place the mou se pointer on the battery symbol, the system displays the battery status.
Battery storage
BatteryBatterySelf-discharge,batteryChargingc apac ity,battery
Store battery packs in a dry environment at a temperature between 0°C / 32°F and 30°C / 86°F. The
lower the temperature at which the batteries are stored, the lower the rate of s elf-discharge.
If you will be storing batteries for a longer period (longer than two months),
the battery charge level should be approx. 30 %. To prevent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at regular intervals.
To be able to ma ke use of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharg ed.
If you do not use the batteries for long periods, remove them from the
notebook. Never store the batteries in the device.
