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 can extend the battery life by taking advantage of the available energy saving functions.
Charging, caring for and maintaining the battery
BatteryBattery
The notebook’s rechargeable battery can only be charged when the amb ient temperature
is between 5°C / 41°F and max. 35°C / 95°F.
You ca n charg e the battery by conne cting the notebook to the m ains adap ter
(see "
Mains adapter connecting", Page 20).
Please note that the battery will not be charged if the battery state of charge is
between 90% and 100%. If the battery sta te of charge is less than 90% and the mains
adapter is connected, the battery will be charge d to 100%.
When the battery state of cha rge is low, a message from the op erating system appears.
If you do not connect the mains adapter within about 5 minutes of the message

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 lowe r the rate of self-discha rge.
If you will be s toring batteries for a longer period (more than two months),
the battery charge level should be approx. 30 %. To p revent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at regular intervals.
To be able to make use of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharged.
If you do not intend to use a battery for long periods of time, remove it from
the notebook. Never store a battery in the device.
If the device will not be used for a period of more than two days, remove the
batteries from the device so that their state of charge is maintained.
