The following computer components consume a lot of power when in use.
- Hard Drive
- Floppy Drive
- Modem
- Network Interface
- The Display
When the computer is not being used, there is obviously scope for reducing power usage by partially turning them off.
We can do the above by choosing appropriate time outs in the power options properties dialog box. For this, we open the Control Panel and then the power options. We can also disable certain laptop features.
After the power options dialog box opens, we can select “Turn Off” option for the monitor and hard disk, so as to send them into the desired mode. This will stop the spinning of Hard drive after a few minutes and also put off the monitor.
This action will result in constant savings of laptop battery. The devices will go in sleep mode and can easily be brought back to life simply by pressing any key or moving the mouse.
We can also choose other hibernation or sleep options from the dialog box. Whatever scheme one chooses, it can be saved under an appropriate name which can be applied again latter on if the scheme somehow gets disturbed.
