The notebook battery can only be charged if the ambient temperature is between
5°C / 41°F and a maximum of 35°C / 95°F.
You can charge the battery by connecting the notebook to the AC adapter
(see "
Connecting the AC adapter", Page 22).
Be aware that the battery w ill not charge when the battery charge level is b etween
90% and 100%. If the battery charge level is less than 90% and the AC adapter
is connected, the battery charges up to 100%.
If the battery is running low, an alert is triggered . If you do not connect the AC adapter within
five m inutes after the alert tone, your notebook will automatically switch off.

The battery should be stored in a dry environment at a temperature between 0 °C / 32 °F and
30 °C / 86 °F. The low er the storage temperature , the lower the rate of self-discharge.
If you will be storing a battery for a longer period (more th an 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 make use of the optimum capacity of the battery, you should allow
the battery to fully discharge and then recharge it.
If you do not intend to use a battery for long periods of time, remove it
from the no tebook. Never store batteries in the unit!
