Managing Power Consumption

Managing Power Consumption
When you are running your notebook on battery power, you can maximize operating
time without compromising performance. Your notebook is designed to help you
reduce power consumption and extend battery life.
During idle periods, the notebook automatically enters power-saving modes after
specified timeout periods. You can adjust these timeouts to suit your working habits.

How the notebook manages power automatically

Your notebook enters Hibernation and Standby automatically, and turns off the hard
drive and display based on values set in Windows.
When this occurs
No keyboard, pointing device, or other
input activity occurs for the specified
interval
The hard drive is not accessed for a
specified interval
No pointing devices are used, no disk
drive is accessed, and no port (serial,
parallel, or infrared) is active for the
specified interval
The notebook stays in Standby for the
specified interval

conserve battery power and
extend the life of the display.

This is usually set to occur
shortly after the display is
turned off.
