During mobile use, the note book runs on its built-in battery. You can increase the
service life of the battery b y caring for the battery properly. The average battery
service life is around 800 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 m a ximum of 35°C / 95°F.
You can charg e the battery by conn ecting the notebook to th e AC adapte r
(see "
Connecting the AC adapter", Page 18).
If the battery is runn ing 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,batteryChargecapacity,battery
The battery shou ld be sto red in a dry e nvironment at a temperature between 0°C / 32°F and
30°C / 86°F. The lower the storage temperature, the lower the rate of s elf-discha rge.
If you will be s toring ba tteries for a longer period (more than two mo nths),
the battery charge level should b e approx. 30%. To p revent exhaustive
discharge which would permanently dam age the battery, check the level
of charge of the battery at regular intervals.
To be able to m ake use of the optimum capacity of the ba ttery, you should allow
the battery to fully discharge and then recharge it.
If you will not use batteries for long periods, remove them from the
notebook. Never store batteries in the device.
