Using the TOSHIBA Sleep Utility

The TOSHIBA Sleep Utility is pre-installed in some models. It is used for

changing settings of "Sleep and Charge function" and "Sleep and Music

function". It also displays the remaining battery capacity.

Sleep and Charge

Your computer can supply USB bus power (DC5V) to the USB port even

when the power of the computer is turned OFF. "Power OFF" includes

Sleep Mode, Hibernation Mode or shutdown state.
This function can be used for ports that support the Sleep and Charge

function (hereinafter called "compatible ports").

Compatible ports are USB ports that have the ( ) symbol icon.
You can use the "Sleep and Charge function" to charge certain USB-

compatible external devices such as mobile phones or portable digital

music players.
However, the "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.

■

When Sleep and Charge function is enabled, 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 sleep and charge function to charge external devices will take

longer than charging the devices with their own chargers.

■

If Sleep and Charge function is enabled, the computer’s battery will

discharge during hibernation or when the computer is turned off. It is

recommended that you connect the AC adaptor to the computer when

enabling the 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.

■

When Sleep and Charge function is enabled, the USB Wakeup function

does not work for compatible ports. In that case, if there is a USB port
that does not have the Sleep and Charge function-compatible icon ( ),

attach the mouse or keyboard to it. If all USB ports have the Sleep and
Charge function-compatible icon ( ), change to disable Sleep and

Charge function. The USB Wakeup function will now work, but the

Sleep and Charge function will be disabled.
