During mobile use, the notebook runs on its built-in battery. You can increase the
service life of the battery by caring for the battery properly. The average battery
service life is around 800 c harge /discharge cycles.
You can extend the battery service life by taking advantage of the available energy saving functions.
Charging, caring for and maintaining the battery
BatteryBattery
The notebook battery can only be charged if the ambient temperature is between
5°C / 41°F and a maximum of 35°C / 95°F.
You can charge the battery by connecting the noteb ook t o the AC adapter
(see "
Connecting the AC adapter", Page 21).
Be aware that the battery will not charge when the battery charge level is between
90% and 100%. If the battery charge level is less than 90% and the AC adapte r
is connected, the battery charges up to 100%.
If the battery is running low, an alert is triggered. If you do not connect the AC adapter within
¿ve minutes after the alert tone, your notebook will automatically sw itch off.

The battery should be stored in a dry environment at a temperature between 0°C / 32°F and
30°C / 86°F. T he lower the storage temperature, the lower the rate of self-discharge.
If you will be storing a battery for a longer period (more 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 a ble to make use of the optimum capacity of the battery, you should allow
the battery to fully discharge and then recharge it.
If you do not intend to use a battery for long periods of time, remove it
from the notebook. Never store batteries in the unit!
