It's somewhat random. Doesn't matter where its plugged on, its temperamental, sometimes the monitor doesn't turn on at all. Sometimes after changing plugs it works. Sometimes after replugging power cable works. Sometimes waiting works. Sometimes its cold, sometimes hot, doesn't matter. Mashing power button nonstop doesn't work. Tried finding something over the internet for this, but there's nothing, it seems like only me have this issue. Still not able to find a pattern where I could tell if it would work or not without trying turning it on, because its so random. Sometimes I lose like 20 minutes on this, sometimes 1, depends. Thanks in advance.

tried with unplugged and re plugged doesn't resume in normal ?.ok check loose connection in the power adapter.if still doesn't resolved the problem, at this time you will need to check the power supply if it is working.you can use a digital tester or an analog to make a voltage checking.
If your monitor doesn't turn on, and you are sure of the power supply (some plug directly into the wall and some use a power adapter), then you can assume that the monitor has failed. You can fix it (replace the power supply in the monitor itself or possibly the on/off switch), have it fixed by someone who knows how to do this, or buy a new monitor. First, of course, be sure the problem is your monitor and not the computer. If the monitor light turns green and then yellow, you can assume it's the computer. If the monitor light doesn't go on at all, it's the monitor.
First I would check to make sure it was still plugged in, you never know, things come loose sometimes. After that check and make sure that the cable that runs from the back of the monitor to the back of your computer is still plugged in. If it's loose push it back in. If that's still not working, try turning the monitor off and restarting your computer, and then turning it all back on. If all that doesn't fix it, then it's probably just gone bad. So either get a new one or if it's still under warranty send it in for repair/replacement.
I absolutely despise monitor and computer sleep or hibernation modes. Before I started routinely disabling this on all the computers I supported my users were always having problems no matter how computer literate they were.
I know this sounds simplistic and you may have already done it but have you just unplugged the monitor?
If that doesn?t work maybe the PC itself has gone to sleep as well. Try moving the mouse, hitting a keyboard key. If that doesn?t work try pushing the power button on the computer to turn it on. If all else fails pull the power plug on the computer itself, plug back in and it should start up. I would suggest disabling all of this via Windows Power settings in the control panel.
