Operating Basics
However, the USB Sleep and Charge function may not work with certain 
external devices even if they are compliant with the USB specification. In 
those cases, turn the power of the computer ON to charge the device.
How to enable/disable USB sleep and charge function
You can set enable/disable USB sleep and charge function in HW setup. 
Please refer to the USB Sleep and Charge function in Chapter7.
Using optical disk drives
The full-size drive provides high-performance execution of CD/DVD-ROM-
based programs. You can run either 12 cm (4.72") or 8 cm (3.15") 
CD/DVDs without an adaptor. A Serial ATA interface controller is used for 
CD/DVD-ROM operation. When the computer is accessing a CD/DVD-
ROM, an indicator on the drive glows.
The USB Sleep and Charge function only works for compatible ports. 
This function is disabled in the default setting. To enable it, you must 
change [Disabled] to [Enabled] in the HW setup.
When USB Sleep and Charge function is set to [Enabled] in HW Setup, 
USB bus power (DC5V) will be supplied to compatible ports even when 
the power of the computer is turned OFF.
USB bus power (DC5V) is similarly supplied to the external devices 
which are connected to the compatible ports. However, some external 
devices cannot be charged solely by supplying USB bus power 
(DC5V).
As for the specifications of the external devices, please contact the 
device manufacturer or check the specifications of the external devices 
thoroughly before use.
Using the USB sleep and charge function to charge external devices 
will take longer than charging the devices with their own chargers.
If external devices are connected to compatible ports when the AC 
adaptor is not connected to the computer, the battery of the computer 
will be depleted even when the power of the computer is turned OFF. 
As such, we recommend that you connect the AC adaptor to the 
computer when using the USB sleep and charge function.
External devices connected to the USB bus power (DC5V) function that 
interfaces with the power ON/OFF of the computer may always be in 
an operational state.
When there is a current overflow of the external devices connected to 
the compatible ports, USB bus power (DC5V) supply may be stopped 
for safety reasons.
Metal paper clips or hair pins/clips will generate heat if they come into 
contact with USB ports. Do not allow USB ports to come into contact with 
metal products, for example when carrying the computer in your bag.
