Padlock symbol in Middle of Screen

  • I have a white padlock (which keeps opening and closing) in the middle of my screen. It is on a square blue background edged in white 3.5cm by 3.5cm. I can't click on it or move it and I have run all my virus and spyware programs to try and remove it. Can anyone shed any light on what it is and how to get rid of it.
    Thanks for your help
  • I found this by searching the forums: <ADMIN NOTE: Broken link has been removed from this post by Dell> Seems to be a monitor setting.

  • It's not spyware, adware or a virus.

    It's a monitor glitch.

    Change the resolution and it goes away then change back to your original resolution.

    I wrote step by step instructions on this page -

    I hope that helps, that padlock drove me CRAZY for an hour.
  • I tried changing the resolution and changing it back and it doesn't make any difference.
    It seems to be a hardware problem with the menu set up keys as the only key that responds is the power key.
    Is there anyway to reset the monitor by holding down some combination of these keys or to replace key pad logic board inside the monitor?  It says that it is a BenQ board?
    Any help would be appreciated as the lcd itself is fine.
  • Well believe it or not, I solved my problem with a penny.  I'm not kidding. A real Lincoln Penny. 
    After messing around for a while I found that if the key with the "X" was held in continuously the blinking padlock went away. 
    I tried to figure out a way to keep this key depressed continuously and nothing seemed to work.  So, what I did was remove the back cover.  You need to take out about 10 screws. Then I took a penny and I put it in front the button for the "X" and I put everything back together and it's working like a charm.
    None of the other keys work except for the power key but they didn't work anyway so I fixed my monitor for a penny.  You can't beat that.:smileyvery-happy:
  • I'll save you a penny.
    The problem appears to be caused by dirty contacts in the buttons. The result is a short circuit, which fools the monitor into thinking that the button(s) are being depressed. If you have a simple understanding of electronics, you can fix this in a matter of minutes (at you own risk, of course).
    Unplug the monitor
    Open it up by removing any screws and/or snaps
    Get access to the button panel
    Clean the contacts with a brush and some isopropanol
    Put everything back together
    Say goodbye to the annoying padlock. :smileywink:
  • Before you do all the things listed above, check your monitor cable.  If it is stretched to tight it will cause this.  Simply move your monitor to release the tension.  Quick and easy fix!
