Monitor Keeps Going Into Power Save Mode – How To Fix

We have all been there, spending hours on our desktops and often dozing off while watching movies with or without our loved ones.

Whatever circumstances that might be, you may have noticed your monitor screen going all black all of sudden as if it has been turned off by a possessed soul.

Don’t worry, your desktop isn’t haunted, well, at least, as far as we are concerned because there is another phenomenon that is happening to your monitor right now which is called Power saving mode.

And if by any chance you, yourself are going through the fiasco of Monitor keeps going into power save mode, then you might be pandering about why is it even happening in the first place and how could I possibly fix it.

Luckily, we have an explanation and a solution, so fret not, and keep on scrolling to find out detailed information about this situation.

First Thing First, What Is Power Saving Mode?

As the name suggests, Power saving mode is a kind of protocol that is keen on saving you from ending up having an exorbitant amount of electricity bills.

As we all know that almost all electronics require some sort of power running in their electrical circuit in order to keep them in optimal working order.

Although it is quite evident that these electronics don’t really get tired from performing their task all day long and as a matter of fact are designed to do it non stop, sometimes are needed to take a quick nap, when they aren’t operated by a human being.

This “Nap” is often monitored and governed by Power saving mode protocol that turns off the display or similar components to save power until it is needed back again.

However, Power saving mode can also be triggered through other means, such as 

  • Inactivity 
  • Windows Power Profile Modes
  • Partially Or Completely Drained Cmos Battery
  • Lack Of Power 
  1. Inactivity 

As explained above, when a desktop isn’t given any task to perform or isn’t governed by an external stimulus i.e Human being in general, often goes into a power nap which results in the triggering of Power saving mode.


Although, this could be prevented by simply performing tasks on your computer by moving its cursor or simply changing the timer that enables your monitor to go to sleep through the Power saving protocol.

Although each Monitor model has its own unique User interface, they often have the same method in order to access their settings by pressing the buttons on your Monitor and navigating to Power settings and toggling off the sleep option.

So that you won’t have to worry about annoying Power naps while you are reading a digital book or watching a movie, handsfree!

  1. Windows Power Profile Modes

Windows also has a unique Power Profile which lets your CPU cores and other components act accordingly depending on the type of profile you set it in. 

However, since most operating systems such as windows, especially the ones on laptops are tweaked to be power efficient and have their Power Profile set to power saving resulting in them turning off the display every now and then.

This could be extremely annoying especially if Windows wants you to log in every time you wake your desktop/Laptop from your deep slumber.


To change it, simply type in “Power management” where you will be welcomed with three default profiles, simply change it to Ultimate Mode, in order to “Monitor wake time” for the longest.

However, if that’s not enough, you can simply turn off the “sleep” option for your monitor by clicking on the said profile and toggling off the Sleep Mode timer.

  1. Partially Or Completely Drained CMOS Battery

A complementary Metal Oxide Semiconductor or CMOS is a small coin-shaped battery that is often installed in a computer motherboard that keeps track of things and provides power while your PC is shut down.

It often charges itself while your PC is turned on, however, sometimes, due to some sort of malfunction it won’t charge itself, resulting in incorrect or abnormal behavior because of a lack of power from the CMOS battery to your monitor.

As a result, your monitor display will be turned off indefinitely or even periodically, depending on the type of situation your CMOS battery is in.


Simply, replace the CMOS battery in your Motherboard by purchasing a new one, or take it to a repair shop and you will be good to go.

  1. Lack Of Power 

Hope for the best that you aren’t facing this issue because it could be some sort of serious underlying problem in your power supply or even your motherboard.

However, if you have tried every method above, here is the solution


If you are suspicious that your power supply hasn’t been performing up to the mark, turn off your computer and check if any cable isn’t loose, that is connected from your PSU to the motherboard.

Try pushing them gently yet firmly into your motherboard to make sure they can establish a connection.

Moreover, if none of this helps, invest in a decent branded Power supply with at least Gold efficiency and check if the issue persists.

Final Word

So that’s all the possible solutions I could provide regarding Monitor Keeps Going Into Power Save Mode, if none of these helps, you can always try taking your computer to a repair shop or even the original manufacturer and apply for Return Merchandise Authorization (RMA) and hope for the best.

As always, thank you for reading, and have a lovely day.
