Pc Entering Power Saving Mode ?

Power saving mode is installed to do a number of things, firstly to help us to be a little bit greener, save a few cents on electricity, or literally hundreds of thousands of pounds for larger corporations.

A power saving mode also helps to increase the lifespan of our pc hardware, after all what’s the point in having a screen powered on all of the time, or a hard drive that’s spinning permanently.

But sadly many people look upon their pc entering power saving mode as a bad thing, it’s going to slow my pc down, is it really? If you have a pc that’s properly configured to use a power saving mode, it’s really the opposite.



A pc that’s left on with no power saving will inevitably get hot, and the hotter a pc gets, the slower it will run.

Think of a pc using power saving as giving it a little break, and once you need to use it again it’s components will be cooler and thus run faster for you.

It’s impossible to setup a pc for someone else when it enters power saving mode, everyone uses a pc differently so it’s better to set it yourself, it’s pretty straight forward.

Firstly many PC’s have two power saving modes, one is part of the operating system and the other is within the BIOS.

To access the BIOS power saving mode simply watch for a setup key when you start your computer, it will usually say something like – press F2 for setup – When your in the BIOS look for the power saving section, the main thing here may be the processor, and other system devices such as the screen brightness if you are using a laptop generally the power saving mode in the BIOS is very limited and will only take a few minutes to configure.

Here you’ll find processor power saving, laptop screen lighting, you can sometimes even disable things such as the onboard LAN port and video ports if needed.

Within Windows select the start menu select Control Panel and then Power Options, under Power Schemes choose the amount of time before a hard disk turns if’s self off, a hard disk will only take a few seconds to come back to life, this will happen as soon as you use the mouse or keyboard, around 15-30 minutes is generally adequate.

The monitor can be set to power off after about 10 minutes, again it only takes a few seconds to return to life, but remember an LCD Monitor has a limited life, normally it’s the back light that fails, the image will still be there but much harder to see, so the longer it’s left on the sooner it will fail.

By setting the power saving it will help prolong its life.

Another great little feature is hibernation, this will enable your computer to boot up much quicker, you can even leave files open and it will retain this when you power on.

Hibernation should not be confused with standby, In standby mode your pc will still use a small amount of power, you should still see a flashing light when in standby, usually the power button.
