USB Sleep and Charge Function and USB Wakeup Function

Troubleshooting

External devices connected to the compatible ports do not work when connected to a compatible port.

❖Some external devices may not work when connected to a compatible port when the “USB Sleep and Charge function” is Enabled in the BIOS setup. Reconnect the external device after turning ON the computer. If the external device still does not work, connect the device to a USB port that does not have the

USB Sleep and Charge function-compatible icon or change the “USB Sleep and Charge function” setting to Disabled in the BIOS Setup.

USB Wakeup Function

This function restores the computer from Sleep Mode depending on the external devices connected to the USB ports. The “USB Wakeup function” operates under Windows VistaTM OS and it works for all USB ports.

NOTE

“USB Wakeup function” will supply USB bus power (DC5V) to all

 

USB ports, including compatible ports, even when the computer is in

 

Sleep Mode. USB bus power (DC5V) will not be supplied if the

 

computer is in Hibernation Mode or shutdown state.

 

When “USB Sleep and Charge function” is Enabled in BIOS Setup,

 

the “USB Wakeup function” does not work for compatible ports. The

 

Wakeup setting (function to allow the Wakeup) check box will be

 

displayed on the Device Manager and even though you can change

 

the settings the USB Wakeup function will not work. If you want to

 

use the USB Wakeup function, attach the mouse or keyboard to a

 

USB port that does not have the USB Sleep and Charge function-

 

compatible icon

.

 

 

 

Troubleshooting

❖When “USB Sleep and Charge function” is Enabled in the BIOS Setup, the “USB Wakeup function” does not work for ports that support the USB Sleep and Charge function. In that

case, use a USB port that does not have the USB Sleep and

Charge function-compatible icon or disable the “USB Sleep and Charge function” in BIOS Setup.
