    Some keys not working on Lenovo|W540

    Esc , Num lock , Up arrow , Num4, F4 , F5 , F6 , ' , G , H and Left Alt are not working on my device.
    I do not know what is the issue. I tried updating my driver, turning off and on filter keys and restarted several times but the keys still do not work. Please help.

    Hi, could you explain why you think this might be a software rather than a hardware problem please?
    What's the story? E.g.
    - It was fine until yesterday, and when I started my PC I suddenly found the keys didn't work.
    - I've just upgrade to build ? and now these keys don't work.
    - my dog knocked my coffee over and it spilt on my keyboard


    Have you confirmed this by using a different keyboard, if available?

    You could also try using a boot disk, e.g. a Win 10 bootable disk, or a live boot disk created using Kyhi's iso, available from the top of the Software and Apps section here, for example. If the keys work when you use that, then it is presumably a Windows problem rather than hardware.

    Thanks for answering!
    I am pretty sure that this is a soft problem as it appeared after an update and that I had not any incidents with my keyboard. I did not check the boot disk because I do not know how to use it.

    Can you specify which update please (Settings, Update History), and what is the build of your current Windows? Windows key + R, winver

    If you have received the latest major upgrade (1809) you would also have received a new set of drivers, which might be related to your problem.

    Boot disk: download ISO, create bootable external drive (e.g. flash drive) - or if you have a DVD drive burn iso to DVD. Tutorials available.

    Insert flash drive/DVD setting boot priority in BIOS appropriately.

    Boot PC.

    E.g. to clean install Win 10 you need a bootable flash drive /DVD with Win 10 on it.

    I got this problem after a Lenovo system update( I don't know specifically which one, and it was one year ago since I have this problem).
    After some hours of a headache, I tried the boot method and my keys doesn't work in this thing.
    My winver is 1803 (OS build 17134.345)

    What is your exact laptop model?
    Have you tried asking on Lenovo's forum?

    What happens if you boot to Safe Mode? Do you have the same problem? (Basic drivers are used in Safe Mode).

    Try this boot disk:
    Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums
    or a Win 10 bootable medium

    Create Bootable USB Flash Drive to Install Windows 10 | Windows 10 Tutorials
    - follow from Option 1 to create a Win 10 boot medium
    - follow from Option 2 using Kyhi's iso

    Sorry for replying so late.
    My exact Lenovo model is ThinkPad W540.
    I tried a Linux live boot to see if it is a windows related problem, apparently, it is not because my keys did not work in Linux.
    I will try asking this problem on Lenovo forums, if I do not get a solution there I think I will buy a new keyboard.
    Thanks for your time!

    Yep, unfortunately sounds like a hardware problem.

    You could try a USB keyboard etc if you can borrow one, but doubt you'd learn more.
