Adjust the power settings on your laptop to conserve energy:
- Right click on the empty desktop background and select Properties.
- Select the Screen Saver tab and hit the Power button.
- Under Power Schemes, you should see two columns, one for Battery and one for Plugged in.
- You can change Turn off monitor and Turn off hard disks to be both the same as System Standby. (You can set them to Never also; not recommended for Battery mode.)
- Hit Apply or OK to save your changes.
