07.Energy saving settings
Here is how to activate PC and Mac energy-saving features.
Windows XP
To enable energy saving settings in Windows XP, right click the desktop, then Properties (or click Control Panel in the Start menu, then Display).
Now click the Screen Saver tab, and under 'Monitor power', click Power. Here you can choose to put your monitor or hard disk to sleep when idle for certain amount of time, and activate your computer 'standby mode'. Standby mode turns off your monitor and hard drive, consuming just a small amount of power in order to save your work into the internal memory (or RAM) of your computer.
Windows Vista
Energy settings are set up differently with Windows Vista. Right-click the desktop, then Personalization (or click Control Panel in the Start menu, then Classic View, then Personalization).
Now click Screen Saver, and then under 'Monitor power', click Change power settings. You can now select one of three preset power plans.
To view or alter the amount of time until Windows switches off your monitor or hard disk, click Change plan settings. To wake your computer, press any button on your keyboard.
Mac
To access the energy saving settings on your Mac, click the Apple menu in the menu bar, then System Preferences, then Energy Saver.
Here you can decide to put your computer, display and hard disk to sleep after a period of inactivity.
For those using notebook Macs such as the MacBook, MacBook Pro or MacBook Air, a separate set of energy saving settings can also be applied when using your notebook battery, allowing you to conserve battery life by pushing energy saving settings even further.
