It is re commended that the notebook be operated with the power s upply connected
whenever the USB p ort with charging function is in use, as this function will drain
the battery more quickly if an external U SB device is being charged.
The po wer supply unit must already be connected when the notebook is
switched off, as otherwise the USB charg ing function will be disabled and
the connecte d USB devices will no t be cha rged.
Some USB devices (e.g. mobile telephones) require a driver in order to utilise the
USB charging function. In this case the USB charging function will not work when the
notebook is switche d off, as no drivers are active when the no tebook is switched off.
You can use this USB port to charge or supply power to a USB device (e.g. to charge a PDA
or a mo bile phone or to connect a USB lamp), even if the notebook is sw itched off.
