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 develop a fault please stop using them immediately.
Do not touch the contacts of the batteries.
Never interconnect the positive and negative terminals of a battery.
Batteries are harmful to the environment. You should dispose of them following guidance
from your local District Council.
Observe the information on battery storage in the "Important notes" 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 begins to flash orange (1 second on / 1 second off). 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.
i
If you do not use the batteries for long periods, remove them from the notebook. Never
store the batteries in the unit.
Monitoring the battery charging level
Power management includes a "battery charge meter" located in the task bar. When you place the
mouse pointer on the battery symbol, the system displays the battery status.
