If you are attempting to charge a device without an AC adaptor 
connected to the computer, the computer's battery power may 
be below the limit specified in the TOSHIBA Sleep utility or 
the battery may be depleted. Lower the limit in the TOSHIBA 
Sleep utility to enable charging at the current battery power 
level, or, if battery power is running low or is depleted, connect 
the AC adaptor to your computer.

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, power on the computer to charge 
the device or use a different charging device.

When the “USB Sleep and Charge function” is set to Enabled 
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 (

), if you have a non-Sleep and 

Charge USB port available or disable the “USB Sleep and 
Charge function.” For more information, see 

A connected eSATA device may not be recognized if it is connected 
to the computer’s eSATA/USB combo port (available on certain 
models) while the computer is in Sleep or Hibernation mode. If this 
occurs, disconnect the eSATA device and then reconnect the device 
while the computer is turned on.

Before connecting the eSATA device to your computer and external 
power source, read the documentation that came with the device and 
follow the manufacturer’s instructions.

If you have followed the recommendations in this chapter and are 
still having problems, you may need additional technical assistance.

Since some problems may be related to the operating system or the 
program you are using, it is important to investigate other sources.

Review the troubleshooting information in your operating 
system documentation.
