Dell monitor entering power save mode, even sometimes on startup is a common issue with Dell monitors, and it occurs for a variety of reasons.
When this happens, the Dell monitor usually displays the message “Auto Detect Entering Power Save” or “Entering Power Save Mode“.
Before you troubleshoot, verify if your computer is responsive or not. An easy way to confirm this is by checking the keyboard buttons with an indicator light, such as Caps Lock. If the light works, your computer is fine.
You can fix this issue by disabling the Monitor Deep Sleep feature. Here’s how to do that:
- Open your Dell monitor OSD (On-Screen Display) Menu.
- Go to Others.
- Select Monitor Deep Sleep and then select Disable. See the screenshot below:
If the issue persists, check the power source and input cables to the monitor. Then, try removing/re-installing RAM or factory resetting your Dell monitor.
Check Power Source
Check the power cable of your monitor. If it is broken or faulty, it won’t be able to supply the appropriate power to your Dell monitor.
As a result, the monitor won’t work or in worst cases, won’t even turn On.
Also, ensure that the socket you have plugged in the monitor cable to is properly working. To confirm that, try plugging your mobile charger into it and see confirm if it is OK.
Check Input Cable (HDMI/Display)
If the power cable and the socket is alright, then check the HDMI or display cable which you are using to provide input to your monitor.
Try replacing the existing HDMI cable with a new one.
If the problem is with the HDMI cable, it will be gone after cable replacement and your Dell monitor will get out of power save mode.
Disable Power Save Mode from Windows Settings
Here’s how to disable power save mode:
- Open Control Panel from Start Menu.
- Type Power Options in the search box and click it. Click on Show Additional Plans and look for display settings.
- Change to option for Turn Off Display to Never.
- Make sure you select this setting for both On Battery and Plugged In options.
- Change the setting from Put the Computer to Sleep to Never.
- Click Save Changes.
If your computer is running on Windows 11, then instead of searching for Power Options, search for Power & battery. The rest of the steps to disable power save mode are the same as above.
Remove and Re-insert RAM
If both the power and display cables are OK, and disabling power save mode in the Windows settings also did not help, then try removing your PC RAM.
Before you do that, first ensure that all the cables attached to your computer and monitor are removed.
Once all cables are removed, unplug memory modules from your computer one by one from the motherboard.
Turn On your computer when all RAM modules are removed. It should give a beeping sound.
After 5-7 seconds, turn Off your computer and install the memory modules back.
Now turn it ON again.
Factory Reset your Dell Monitor
If you have tried all of the above solutions and none has worked, then there’s one more fix – factory reset the monitor.
To factory reset your Dell monitor, follow these steps:
- Press the 3rd button to open the On-Screen Display Menu.
- Press the last button from the left to open the Others options.
- Scroll and select the Factory Reset option in the menu and confirm the selection by pressing Button 3.
