Power supply mode settings

Your computer may provide two different charging modes, to
support various types of USB devices. If your computer provides
more than one charging mode, the charging mode you should select
depends on the USB device you want to charge. For example,
Typical Mode, which is the default mode, will charge a wide
variety of digital audio players. If your device does not charge in
Typical Mode, try using Alternate Mode. To select a different
charging mode, use the Power supply mode drop-down list in the
utility.
NOTE
With certain external devices, the USB Sleep and Charge function
may not work no matter which charging mode you select. In those
cases, disable USB Sleep and Charge in the utility and turn the
computer on to charge the device, or use a different charging device.
