    My Computer screen keeps turning off but turns on when I plug in the power cord


    So I have a Lenovo Laptop and whenever I unplug the power cord the screen fades out as if my brightness is changing. Whenever I put in the power cord it returns to normal. But when I type or press anything it is still going through.

    Plugging in power cord turns off screen in Windows 10. Please Help!

    I have an Acer Aspire E15 laptop, I've been using it with Windows 8.1 until I did a clean install of Windows 10 recently. Normally, when I get the warning notice that I have 10% power left, I plug in the power cord and continue work. But now when I plug
    the cord in, it turns off the screen (goes black). I still get audio but no video. If I unplug the cord, the screen comes back. What's going on? I've never had this issue with Win 8.1 or any other OS version before.

    Unplugging power cord and holding the power button. PC won't turn on

    Okay so I attempted to fix a Windows 10 usb problem by following a month old forum. The instructions were:

    1. Unplug the power cord from desktop computer.
    2. Hold in the on/off button for approx. 10 seconds until the light goes off. This kills the reserve power.
    3. Unplug all of your USB cords from the back of your machine as well as any flash drive or any other USB
      device that is plugged into your computer.
    4. Insert the power plug back into your computer and power it up. Allow it to completely load everything
      that it needs to before you do anything else.
    5. Now start plugging your USB devices back into your computer one at a time while waiting for them to
      indicate that they are recognized. Do this with each one of your devices until all have been recognized.
    6. Now right/click on computer or This PC and choose Manage / Device Manager /USB Serial Controllers and
      check to see if any of them have the yellow tag. They should not have if the problem is corrected.

    Unfortunately I only got to Step 4, when I press the power button nothing turns on. So now I'm at a complete loss. The only thing that seems to turn on though, would be the lights to my led keyboard when I plug it in. Anyways, how do I fix/turn on my PC again?

  4. My Computer screen keeps turning off but turns on when I plug in the power cord

    Plugging in power cord turns off screen in Windows 10. Please Help!

    You can control the brightness separately for "battery" versus "plugged in". And it sounds like the "while plugged in" brightness is set to 0%.

    Here's what I'd do:

    • Type "Power Options" in your Search box
    • Next to your current power plan, click the blue "change plan settings" link
    • Under the "plugged in" side, drag the slider up to increase the brightness for while the cord is plugged in.
    • Be sure to click Save Changes when done

    After that, try plugging it in again.
