When not plugged into a power outlet, the notebook runs on its built-in bat tery. You
can increase the life of the battery by caring for the battery properly. The average
battery life is around 500 charge/discharge cycles.
You can extend the battery life by taking advantage of the a vailable energy saving functions.
Charging, caring for and maintaining the battery
BatteryBattery
The notebook battery can only be charged, when the ambient temperature is
between 5°C / 41°F and ma x. 35°C / 95°F.
You can charg e the battery by conn ecting the notebook to th e AC adapte r
(see "
AC adapter con nectin g", Page 17).
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 w ill automatically switch off.
Monitoring the battery charging level

Windows also has a "Battery status meter" in the taskbar for monitoring the battery capacity. W hen
you place the mouse pointer on the battery symbol, the system displays the battery status.
Battery storage
BatteryBatterySelf-discharge,batteryChargingc apac ity,battery
Keep the battery pack between 0°C / 32°F and 30°C / 86°F. The lower 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 two months),
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 make use 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, remove them from the
notebook. Never store t he batteries in the device.
