Using Power Saving Modes

This is the normal state of your computer when it is in use. The green power 
indicator light is on in this mode. To save power, you can turn off a specific 
device such as the LCD or the hard disk.

This mode is convenient if you do not need to use your computer for a brief 
period. The hard disk and video display enter a low power state, and the CPU 
clock and processor stop. The power indicator light is tan in this mode.

Press Fn+S. You can also use the PowerPanel utility to enter System Idle mode.

To return to normal Mode

The computer saves the current state of the system in RAM and switches off 
power to the CPU. The tan power indicator light flashes in this mode.

To activate System Suspend Mode

Press Fn+Esc. You can also use the PowerPanel utility to enter System Suspend 
mode.

To return to normal Mode

Press any key.

The state of the system is saved on the hard drive and power is turned off.
