Transport Mode
The laptop is in secure transport mode after being unpacked; this prevents accidental
switching on and discharging the battery.
− Before switching on for the fi rst time, you must connect the AC adapter and wait
around 8 seconds before activating the on/off switch.
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 signifi cantly longer.
The charging process is interrupted if the battery temperature gets too
high. Left-click on the battery symbol in the taskbar to display the battery
status, and, if necessary, use the
F1
key to open Windows Help.
Discharging the Battery
Operate the notebook on battery power until it turns itself off due to low battery
charge.
NOTICE!
Loss of data!
A sudden power failure may result in the loss of data.
− Be sure to save your open fi les promptly to prevent any data
loss.
Battery Life
The actual operating time varies depending on the confi guration of the power-
saving functions. Note: your notebook consumes more power when running certain
applications.
The battery life will be reduced if the processor or graphics components of the
notebook are used to capacity over an extended period of time. This can occur in the
case of games with elaborate graphics, videos, music editing or graphics editing.
If you ignore the low battery warning, your notebook will shut down.
