    Strange Keyboad Problem - Selective Remapping?


    Iíve been experiencing some strange keyboard problems on my laptop.

    Technical background info:
    Windows 10, Version 1909 (OS Build 18363.778)
    Trekstor C11 Laptop (The laptop is a German model with a German keyboard)
    Keyboard layout on the laptop is German QWERTZ
    Windows Display Language is set to English (United States)
    Windows Preferred Language is set to English (United States) with the German keyboard layout
    German is set as a secondary preferred language
    Region is set to United States

    Now to describe the problem.

    Regardless of what program is running Ė it could be LibreOffice, Word, or Firefox Ė the cursor will spontaneously start to move up through the document. I first noticed the problem in Firefox, when the problem manifested itself with the webpage scrolling upward for no reason. The problem has even happened in Paint, where the cursor or selected area will spontaneously start to move straight up through rest of the image.

    Another problem that has been occurring is that the control key will act as an up-arrow key. So, for example in LibreOffice, if I hit Ctrl+v to paste, the cursor first gets moved up one line before the paste event occurs, so the clipboard item is pasted one line higher than expected.

    A similar problem is happening with the shift keys. They too are being remapped as up-arrow keys. So for example if Iím typing in Word, and want to type a capital letter, pressing shift will cause a selection to appear from the original cursor location and up one line (just like making a selection manually where you hold down shift and use the arrow keys to create the selection area.) (See attached screenshot)

    None of the keys on the keyboard are damaged or stuck. The arrow keys, the shift keys, and the control key are all fine, with no physical damage, food deposits or anything else that would cause the keys to act strangely. I have never before had any problems of this sort. Windows updates have all run smoothly.

    To be 100% sure that the keys themselves are not the problem, I attached an external USB keyboard to the laptop. At the first instance when the problem re-occurred, I stopped using the laptop keyboard and started using the USB keyboard. The external USB keyboard causes the same exact problems!

    A few further technical notes:

    The problem is by no means constant. After turning on the computer, it takes about 20 minutes before the problems start. Then sometimes the matter resolves itself and all seems well only for the issue to recur a few minutes later.

    When the problem is occurring, pressing caps-lock will cause the caps-lock LED to flicker as if the button is being pressed repeatedly several times per second. When this happens, the OSD on-screen icon showing that Caps-Lock has been pressed also repeatedly flickers between caps-lock-on and caps-lock-off.

    When the problem is occurring, and Iím using Word or LibreOffice, Iíve noticed that pressing and holding down the delete key results in a very sluggish deletion of words. Itís as if itís busy doing something else. When the problem isnít happening, holding delete is really quick to delete a line of text. Also, the left or right arrow keys don't respond when being pressed and held down. You have to click them for each left or right as needed.

    The left shift key is more badly affected by this problem than the right shift key. The right shift key is sort of usable as long as I donít hold the shift key down too long.

    Sticky keys are not enabled.

    None of these problems occurred before Windows was updated to Version 1909.

    One thing that I have noticed is that when this problem manifests itself, the area of the laptop keyboard around the left shift key is hotter than normal.

    Iíve tried uninstalling the keyboard via the device manager, but with no effect.

    Can anyone suggest a way forward to solving this problem? Itís as if the keyboard (both the laptop keyboard and the external USB keyboard) are being selectively remapped and then being restored to their default setting when the problem subsides.

    Hi when did this issue start happening? Could you try a restore point before the issue started.

    Have seen folks, including my wife and I, having difficult in paying attention to where their thumbs and fingers are when using Notebooks, seems some things are quite sensitive to motion detection. Wife turns her touchpad off and uses a USB mouse instead, the neuropathy in my fingers is another issue.

    oscer1 -- Unfortunately, I don't have system restore set up on the machine. The problem only started about two weeks ago and a few days before I noticed the problem, I recall that Windows completed a major update.

    Berton -- I was thinking the same thing when the problem first began, like maybe I was brushing the touchpad area. Disabling the touchpad was one of the first things I did, but it had no effect on the problem. And the problem persists even with an external USB keyboard, so I can definitely rule out unintentional touchpad input as an issue.

    I suspect it has something to do with keyboard mapping, but so far I've not be able to figure it out. I hope someone can shed some light on this. It's sure annoying having to watch when I use shift when typing and having pages scrolling upward automatically!

    oscer1 -- thanks for the link. The link mentions that the file Windows.old will be created. I've got very limited space on the machine, so this may not work out, but I will look into it in more depth. It may be the only thing I can do at this point.

    In the meantime, if anyone has any further suggestions, I'd be grateful for any input.

    Hi W 10, welcome to Ten Forums.

    My money is on hardware. Software would usually create a more consistent type fault where-as what you're describing is bordering on erratic.

    I have a few questions;

    1 - Do you have a scroll lock key, does toggling the scroll lock key change any of this behavior?
    2 - Do you use a wireless mouse with a USB transceiver, have you tried removing the dongle or changing USB ports?
    3 - Have you tried logging in with another user or create a new user for testing to see if the scroll behavior changes?

    W10 Tweaker -- I don't have a scroll lock key, so I used the on-screen keyboard to engage scroll lock and unfortunately, there is no difference. The problem persists.

    I use a wired USB mouse. I've tried unplugging the mouse, but also no change in circumstances.

    I've only got one user on this, so I will set up a new user and get back to you as soon as I can.

    Could you please also try disabling the on-screen keyboard and test results?

    So, I disabled the on-screen keyboard, but to no avail.

    I set up a second user account, but even during the setup of the other user account, there were indications that the problem was still present. On setting up a user account, you have to set up the privacy settings, and on all the sliders, I kept having the problem that as soon as I deselected a particular feature (slide to left), it would almost instantly slide back to the right. So the arrow keys were again active.

    I finally got through it, and logged into the second account and the problem persists. Shift and Ctrl cause upward movement and if I open a large text file and place the cursor at the end of the file, the cursor starts moving up.

    When I attached an external USB keyboard to the laptop, and used the shift and control keys on the USB keyboard, they created the exact same problem as if I were still using the laptop keyboard. Would this in any way change your view that it is a hardware problem? If an external keyboard produces the same problem, it seems that the root must be software-based, or am I missing something?
