Why Is My Monitor Entering Into Power Save Mode?
Entering power save mode after the preset amount of time elapses in the display settings is perfectly normal and means your monitor is working fine.
It helps your PC and external monitor to conserve energy and save power.
However, if you have followed our steps above and decided to never allow power save mode from activating and your system still chooses to enter power saving mode, there are a few common problems that may be the cause.
Here are a few common reasons for it and how to resolve them.
One of the most common reasons why you are having issues with power save mode is down to limited signals coming from a faulty connection.
- 1Unplug and replug your monitor connections to your computer, ensuring that they connect snugly once plugged in
- 2While you disconnect and connect these cables, inspect them for damage and try them in other ports or outlets to ensure that they are working.
- 3Replace any power cable that is no longer functional with different cables.
If it continues, you may need to power cycle your monitor.
- 1Turn off the monitor and PC at the power button and unplug the monitor and PC
- 2Wait for at least 30 seconds
- 3Plug in and turn your system back on again
- 4You may need to do this 1-3 times
Finally, more tech-savvy PC users with a Thinkvision monitor or another brand like Samsung or LG monitor may try to get stuck in.
To try a more hands-on method, you may want to inspect your RAM sticks and CMOS battery to confirm that they are connected and communicating effectively.
Users who experienced similar issues with stand-by mode or safe mode found that reconnecting these solved the issue.
- 1Power off your system by holding the power button and unplug everything
- 2Unscrew and remove your case panel
- 3Expose the motherboard and firmly press on the DIMM slots tabs to remove the RAM modules
- 4Gently wipe the modules clean with a cotton swab or dry microfiber cloth
- 5Replace the RAM modules
- 6Consider replacing your CMOS battery if you have not done so in a long time
- 7Replace the casing and peripheral connections to your PC
- 8Plug it in and turn it on to confirm if that fixed the power-saving mode issue
One of the most common problems can occur after changing your monitor.
Getting a new one or adjusting the monitor settings can cause your system to revert to power save mode to indicate a resolution error.
You can fix this by:
- 1Open Display Settings
- 2Go to Resolution
- 3Try lowering the resolution
- 4Keep adjusting until you find the right one for you
Many users find that a faulty GPU may be the case when it comes to troubleshooting their computer's Lenovo monitor.

- 2Go to your control panel
- 3Find your graphics card settings
- 4On the left-hand panel, click 3D settings>Manage 3D settings
- 5Choose Integrated Graphics in the Preferred Graphics menu
- 6Select Apply to save those changes
- 7Restart your computer to see if that helped
Another option to consider is to update all your software and, if you are a Dell monitor or PC user, update the BIOS from the Dell site.
Customize the settings to best suit you and see if that helps with the stuck-in-power problem.
BIOS settings can also be fixed another way.
- 1Shut down your system
- 2Boot it back up and click the F8 key on your keyboard
- 3Select Hibernation from the boot options
- 4Turn off Hibernation
- 5Click Apply

Another potential fix for your power saving mode issue is to adjust the integrated graphics card or GPU connection setup.
- 1Examine your monitor and PC’s ports carefully to ensure that you have the right cables and ports
- 2Connect your monitor to the DVI (Digital Visual Interface), DisplayPort, or the HDMI cable that came with the monitor.
- 3If you only have a VGA port to work with, you may need to get an adapter to convert the signal to DVI or DP/HDMI
After all of this, if you still find that you are having no video signal or limited signals that lead to power save mode, you may want to use Troubleshooter.
- 1Go to System Settings>Troubleshoot Settings
- 2Select Additional Troubleshooters
- 3Select Power
- 4Click Run
- 5Follow the required instructions suggested by your Troubleshooter
What Is The Purpose Of Power Saving Mode?
Power save mode was originally designed to save energy while your system was not in use. By letting your Dell monitor blackout, your Dell computer could use less residual energy.
By using less energy in the LCD and monitor itself, you can save money on your electricity bills and keep your system working efficiently for a long time to come.
So why is using power save mode and residual power a problem for some?
When power saving mode is activated, it takes longer to get back into your system and get back to what you were doing before.
Power save mode suspends these tasks, taking time to reload the software and re-establish communication with your monitor's driver.
This can cost you time but also data if you do not save before leaving your desk.
All of this adds up to compelling reasons for some to choose to delay or suspend power save mode entirely.
