    The m, c and shift keys on my laptop keyboard intermittently stop working.


    The m, c and shift keys on my laptop keyboard intermittently stop working.


    This always happens when the computer starts up from being completely shut down or after it has been in sleep or hibernate mode.


    To make m, c and shift keys work again, I press the m and k keys at the same time over and over again until the m key starts working. Then, I hold the m key down and just let it run for a while. After the m key starts working, I press and hold the c key and just let it run as well.


    After the process I just described and after the computer has been running for a while, the m, c and shift keys work just fine. If I close the laptop, which puts it in sleep mode, and leave it that way for a while, the problem returns when I open the laptop and try to use those keys again.

    I have tried a number of suggested fixes I have found on the internet. Including:

    Running the Windows 10 Keyboard Troubleshooter - No problem found.

    Sticky Key changes in Settings - No help.

    Updating keyboard drivers to include Uninstalling Device - Didn’t help.

    Starting the computer in Safe Mode - The m, c and shift keys don’t work here either.

    Running Windows update – No help.

    Updating my BIOS – No help.

    Cleaning the keys - No help.

    Using a USB connected keyboard – this works, no m, c and shift keys problems.

    The on-screen keyboard works just fine.

    All of the other keys on my keyboard work just fine.



    Any ideas?

    :)

    Both shift keys

    Hello.
    I have problem with Lenovo Idea Pad 100 laptop (OS: WIN10). After replacing HDD into SSD I faced a strange problem. Both Shifts of the keyboard doesn‘t work .
    I have tried to:
    • Check if sticky keys are off. They are off.
    • Connect external keyboard via USB port. Shift keys on external keyboard works good.
    • Check the keyboard on online tester which indicates pressed buttons. It can‘t indicate press of the shift
    • Change several different input languages. The problem is on all of them.
    • Reinstall keyboard driver
    • Check if connection is OK. It is OK.
    • Tried to run computer without screws (I have read in one forum that screws could touch the keyboard from the bottom and it wouldn‘t operate normal)
    I believe that keyboard is not damaged because connector damage could cause just exact part of keyboard failure, while it is impossible to do physical damage for both shifts. Any solutions?

    random keyboard keys stop working?

    i went out today and everything was fine, i come home and three random keys stopped working, maybe more i havent noticed yet. the three key on the left side of the keyboard not working, the left shift stopped working, and the enter key stopped working, but the one on the numpad works fine. no one was home to use it, nothing spilled on it, i tried it on another computer and same deal. im gonna go buy a new one tomorrow but it makes me sad cause i loved this keyboard lol, microsoft ergonomic 4000. ill probably buy the same exact one if its in stock tomorrow, this one lasted or 4 years about. im just confused why three random keys spread out stopped working at the same time...seems very weird

    Some keyboard keys stopped working after windows 10 upgrade


    Has the Notebook been worked on? Do any of those keys work if holding down the Shift key? Have you used compressed air to blow out any crud that may be blocking the keys?

    It's not expensive nor hard to replace the keyboard, usually can find a video or step-by-step articles on the 'net.
