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.
