9.5. Battery Mode
PLEASE NOTE!
Batteries store electrical energy in their cells and then
release it again as required.
Please charge and discharge the new battery
completely two or three times consecutively to ensure
that it reaches its optimum performance!
9.5.1. Charging the Battery
The battery is charged using the AC adapter. When the AC adapter is connected, the
battery charges automatically regardless of whether or not the notebook is switched on
or not. A complete charge takes a few hours with the notebook switched off. With the
notebook switched on, the charging process takes significantly longer.
PLEASE NOTE!
The charging process is interrupted if the battery voltage or
temperature gets too high.
9.5.2. Discharging the Battery
Operate the notebook on battery power until it turns itself off due to low battery charge.
PLEASE NOTE!
Be sure to save your open files promptly to prevent any data loss.
9.5.3. Battery Performance
The actual operating time varies depending on the configuration of the power-
saving functions. Note: your notebook consumes more power when running certain
applications, e.g. when playing a DVD.
PLEASE NOTE!
If you ignore the low battery warning, your notebook will shut down.
