HP 2311x Monitor Keeps turning on and off periodically. Unable to use.

[Steve-Waltin]

The HP recently started to show this weird activity where I would be using and it would completely turn off, not sleep, just go off. Then it comes on after about 10 seconds, then goes off again after about 10 secedes. This cycle just keeps repeating. 

But if turn it off completely, that is off the power switch at the socket, then turn it on after a while, the monster stays on continuously for about a few minutes. Then it proceeds to repeat the same cycle.

@Steve-Waltin Welcome to HP Community!

I understand that the HP 2311x Monitor Keeps turning on and off periodically.

1. Cycle the power on the monitor as follows:

   1. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.

   2. Unplug the power cord.

   3. Wait 5 seconds.

   4. Plug in the power cord.

   5. Press the power button on the monitor to turn on the monitor.

      One of two things happens:

      • The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode on the computer. For some computers, updating the BIOS can correct these types of suspend problems.

        OR

      • The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps.

2. If the computer is on, wait until the hard drive activity light on the computer is not lit and then press and hold the Power button on the computer case until the computer turns off.

3. If the monitor has a factory reset or restore option, set it. Press the Menu button on the front panel and select Factory Reset.

4. Wait 5 seconds and then turn on the computer by pressing the Power button again

Please update the windows update on your computer.
