Power Saving for Computer

It is possible to save power even though your PC is ON, by using power saving options available. This green initiative will help do little green for the environment around and reduce your electricity bills a bit.

Please note that: All the power options mentioned used the last moment, when it detected inactivity (no mouse or keyboard usage) as reference.

This is the thing you need to do

Right click on the desktop and click on ‘Properties
Next click on the ‘Screen Saver‘ tab above
Click on the ‘Power‘ button at the bottom of the window
This will open a window with title ‘Power Options
Here you can create various power schemes for various requirements. (I have displayed my power schemes at the end of the post)

Power-management in Windows XP

Power-management in Windows XP

Description of terms used:
Turn off monitor: After the selected time limit, the CPU will put the monitor in standby mode. This helps in saving lot of power especially in case of CRT monitor. I will recommend all of us to use this option set to ‘After 3 minutes’.

Turn off hard disks: After the selected time, the power supply to hard-disk is turned off. This helps save a few tens of watts of electricity.

System Standby: This option put the system in a low power mode, turning off most of devices connected to the motherboard. This helps save a lot of power. To resume back to work after standby, just press any key on the keyboard.

Hibernate option in Windows XP

Hibernate option in Windows XP

System Hibernates: This option turns-off the computer completely. You can even switch off the computer after putting it in hibernate mode. To resume from standby mode press the ‘Power’ switch of your CPU. This mode saves maximum power and is equivalent to turning off computer, but it enables to get back to work faster, than turning off the computer and then start it again.

To manually put your computer in hibernation mode, Click the ‘start’ button. Then click on ‘Turn off Computer’. After that, hold down the ‘Shift’ key on the keyboard, the standby button will turn to hibernate. Don’t release the shift key before clicking on Hiberate.

This is how Hibernate mode works: Before turning off, the data in RAM is copied to the hard-disk. So the next time you start your computer, the data in hard-disk is copied directly to the RAM instead of verification process, and you get back where you originally were much faster.

Some of my Power  Management schemes are:

Scanning Power Management: For antivirus scans
Turn off Monitor:     After 1 min
Turn off hard disks:  Never
System Standby:       After 3 hours
System hibernates:    After 4 hours

Usual: For Regular Use
Turn off Monitor:     After 1 min
Turn off hard disks:  Never
System Standby:       After 3 minutes
System hibernates:    After 10 minutes

Movie Time: For use while watching movies
Turn off Monitor:     Never
Turn off hard disks:  Never
System Standby:       Never
System hibernates:    Never

You can create multiple power management schemes, by selecting the required settings discussed above and clicking the ‘Save As’ button and use them to as and when required. Using these measures will contribute to save our warming planet.
