How To Fix “Power Button Lock Out” On Monitor

If you’re getting this message on your monitor then you might not be able to turn your screen off. Here is how to fix it quickly and easily.

Many users have reported this problem with HP monitors and I’ve had a few in my shop over the past few years.

Fix #1:

Disable the monitor’s Power Button Lockout Function by pressing and holding the power button for 10 seconds.

Fix #2:

If the first fix doesn’t work then you can do what is called a factory monitor reset.

Simply unplug the monitor from power (unplug from the wall). Then press and hold the power button for 40 seconds.

Then plug the monitor back into the wall and turn it on.

  1. Thank you for the help! Fix #1 and Fix #2, in that order, did not work, but after completing both, then running Fix #1 again, solved the problem. Thank you, again.

  2. Does not solve problems. Is this a monitor or video card issue? What is third solution, a new monitor?

  3. At first I thought it was possibly my J3 Galaxy mobile phone. But … no luck. Then I tried doing a web search for “Power Button Lockout” and followed a comment solution for holding the monitor power button for a few seconds until the message disappeared. It worked. Thanks!

  4. I had the same issue. After further investigation, I found that the resister labelled RV3, which is in parallel to the power button was faulty. I removed it and my menu is now accessible

  5. Your solution worked—-HP’s solution failed—thanks for keeping ahead of the manufacture.

  6. I am talking about a NEW HP Z38c 72″ Monitor in use 2 weeks that does not render startup screen when I “restart”. I must turn MAIN power switch OFF/ON right after powering on PC after having to turn OFF PC as restarting renders no screen, only input messages telling me my HDMI is connected! Would this be the same?
