Battery
The battery supplies your notebook with the necessary power during mobile use. You can increase
battery life by enabling the system's power management features.
The battery charge is indicated by the battery symbol in the status indicator panel (see also section
"Indicators") When you switch on the notebook, it takes a few seconds before the battery status is
displayed.
The standard battery will last for roughly 500 charge/discharge cycles, this will vary according to
which battery pack is fitted.
Charging, caring for and maintaining the battery
!
Only use batteries released for your notebook.
Take care not to drop the batteries or otherwise damage their casing (fire risk).
If the rechargeable batteries are defective, they must not be used.
Do not touch the contacts of the batteries.
Never interconnect the positive and negative terminals of a battery.
Used batteries must be disposed of in accordance with local regulations (special waste).
Observe the information on battery storage in the "Important notes" chapter.
Information on the battery charging time is contained in the "Technical data" chapter.
You can charge the battery by connecting the notebook to the power adapter.
The battery can only be charged when the ambient temperature is between 5°C and max. 40°C.
Work in the battery mode until an acoustic warning or a message on the screen prompts you to
recharge and the battery indicator in the status indicator panel begins to flash. The battery should
not be charged before this point.
If you do not connect the power adapter within five minutes of the signals described above, your
notebook will automatically switch to the energy-saving mode or off.
Storing the battery
Store the battery in a fully charged state. Keep the battery pack between 0°C and +30°C (32 and
122 degrees Fahrenheit). The lower the temperature at which the batteries are stored, the lower is
the rate of self-discharge.
If storing for a long period of time (longer than two months) batteries should be fully charged before
storage.
To be able to make use of the optimal charging capacity of the batteries, the battery should be
completely discharged and then fully recharged.

store the batteries in the unit.
