Connecting external devices
USB connection with charging function
USBchargingfunction
If you connect USB devices to this USB port, you should operate your
notebook using power from the mains adapter, otherwise the battery will
discharge when the notebook is switched off.
The power supply unit must already be connected when the notebook is
switched off, as otherwise the USB charging function will be disabled and
the connected USB devices will not be charged.
Some USB devices (e.g. mobile telephony) 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 switched off, as no drivers are active when the notebook 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 mobile phone or to connect a USB lamp), even if the notebook is switched off.
The USB port with charging function has its own status indicator. If a USB device is connected
to this USB port, this will be shown by the status indicator as follows:
Mains adapter connected:
•
Indicator lights up green: The notebook is switched on.
•
