Charging, caring for and maintaining the battery
The notebook battery can only be charged, when the ambient temperature is between 5 °C and
max. 35 °C.
You can charge the battery by connecting the notebook to the power adapter (see "Connecting the
power adapter").
A notebook battery will fully charge in approximately three hours in a notebook that is switched off.
A notebook battery will fully charge in approximately 4.5 hours if the notebook is switched on.
It is a good idea to discharge the battery completely before recharging it, as this will extend battery
lifetime. Work in the battery mode until a warning tone indicates the need for charging. The
notebook 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 off.
Monitoring the battery charging level
Windows also has a "Battery status meter" in the taskbar for monitoring the battery capacity. When
you place the mouse pointer on the battery symbol, the system displays the battery status.
