BatteryBatteryServicelife,batteryRechargeablebatteryBattery
During use as a portable, the notebook runs on its built-in battery. You can increase
the service life of th e battery by ca ring for the battery properly. The average battery
service life is around 500 charge/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 ma ximum of 35°C / 95°F.
You can charge the battery by connecting the notebook to the AC adapter
(see "
Connecting the AC adapter", Page 18).
If the battery is running low you will hear a warning alarm. If you do not connect the AC adapter
within five minutes of the warning alarm described above, your notebook will automatically switch off.

Windows also has a "Battery charge meter" in the taskbar for monitoring the
battery capacity. When you place the mouse pointer on the battery symbol, the
system displays the state of charge of the battery.
Battery storage
BatteryBatterySelf-discharge,batteryCharge capacity,battery
The battery should be stored in a dry environment at a temperature between 0°C / 32°F and
30°C / 86°F. The lower the storage temperature, the lower the rate of self-discharge.
If you will be storing ba tteries for a longer period (more than two months),
the battery charge level should be ap prox. 30%. To prevent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at regu lar intervals.
To be able to m ake use of the optimum capacity of the battery, you should allow
the battery to fully discharge and then recharge it.
If you w ill not use batteries for long periods, remove them from the
notebook. Never store batteries in the device.
