Hibernation Mode This feature lets you turn off the power to the
computer without exiting from your software. The
contents of main memory are automatically
saved to the hard disk drive so that when you
next turn the power on again, you can continue
working right where you left off. Refer to the
Turning off the power section in Chapter 1,
Getting Started, for more details.
Sleep Mode If you have to interrupt your work, you can use
this feature to allow you to turn off power to the
computer without exiting from your software.
Data is maintained in the computer's main
memory so that when you next turn on the
power, you can continue working right where you
left off.
USB Wakeup function This function restores the computer from Sleep
Mode depending on the external devices
connected to the USB ports.
For example, if a mouse or USB keyboard is
connected to a USB port, clicking the mouse
button or pressing the keyboard will wakeup the
computer.
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.
