the battery automatically, no matter if the notebook is turned on or off. If the notebook is
switched on, the charging process takes a significantly longer time.
Note
The charging process will be interrupted if the temperature or the
voltage of the battery is too high.
Discharging the Battery
Operate the notebook on battery power until it switches off automatically.
Note
Remember to save your open files in time to avoid possible loss of data.
Battery Performance
The battery life time during a session will vary depending on the setting of the energy
saving function in Windows. You can adjust these to your requirements under
Energy
Options in System Control . Apart from this, your notebook will require more power
when carrying out certain tasks, such as playing back a DVD.
