During mobile use, the note book runs on its built-in ba ttery. You can increase the life of the battery
by caring for the battery properly. The average battery life is around 800 charge/discharge cycles.
You can extend the battery life by taking advantage of the available energy saving functions.
Charging, caring for an d m aintaining the battery
BatteryBattery
The notebook battery can only be charge d 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 adapter
(see "
Mains adapter connecting", Page 17).
If the mains adapter is connected when the state of charge of the battery is more than 90%,
charging will not be started. When the state of charge of the battery is less than 90%, the
battery w ill be charged to 100% as soon as the mains adapter is connected.
If the battery is running low you will hear a warning alarm. If you do not connect the mains adapter
within five minutes of the warning alarm described above, your notebook will automatically switch off.
Monitoring the battery charging level
BatteryBatterystatusmeter
Windows also has a "Battery status meter" in the taskbar for m o nitoring the battery capacity. When
you place the mouse pointer on the battery symbol, the system displays the battery status.

Keep the battery pack in a dry environment at between 0°C / 32°F and 30°C / 86°F. The lowe r
the temperature at which the batteries are stored, the lower the rate of self-discharge.
If you will be storing batteries for a longer period (longer than tw o months),
the battery charge level should be approx. 30 %. To prevent exh aust ive
discharge which wo uld perma nently damage the battery, check the level
of charge of the battery at regular intervals.
To be able to make u se of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharged.
If you do not use the batteries for long periods, r emove the m from the
notebook. N ever store the batteries in the device.
