    Pointer (mouse or trackpad) never falters, clicks and keystrokes do


    Hello there,

    I installed a clean version of Win 10 Pro 1909 on a HP laptop EliteBook 8770W. At the same time, I replaced the HDD with a new Samsung EVO 860 SSD. Most drivers came with Win 10, the rest from several HP sites. The wireless mouse is a plain Logitech M325.

    Every time I'm trying to do something, I'm randomly interrupted. Let's say I need to move some windows around: I set the pointer on the window, then click and drag it. But the click doesn't register and the focus stays set where it was. If I used the mouse, just clicking with the pad gets the mouse working again. And vice versa.

    Now, I want to rename a file: click click to select, then type another name. Right? Not always. Sometimes keystrokes don't work and/or are interpreted as KBD shortcuts to lauch some app (Mostly Cortana).

    I successfully tested the KBD with an HP tool, where you have to type successively on each key. Some keystrokes randomly did not work, sometimes once only, or several times in a row. I noticed that when a keystroke was not working, a symbol shows above the pointer to disappear with the next working stroke: 2 opposite arrowheads separated by a dot inside a circle, what you get when pressing a mouse middle button.

    So the physical equipment is working (the mouse was tested on another machine). The issue seems to lay with the interrupts handling.

    I tried reinstalling Windows to no avail.

    Windows is up to date, Device Manager shows no ! and all drivers have been checked for new versions. All HID, mouse & KBD drivers are from Microsoft, except one from Logithech and one from HP.

    Thank you.

    Hi,
    I successfully tested the KBD with an HP tool, where you have to type successively on each key. Some keystrokes randomly did not work, sometimes once only, or several times in a row.
    - that doesn't sound like a successful test ??

    Most drivers came with Win 10, the rest from several HP sites.
    Did Win 10 not provide all the drivers needed? Why did you have to search for them?

    This PC seems to date from 2013: it appears to have limited support for Win 10:

    The latest BIOS appears to be May 2019 - is this up to date? Drivers appear complete for Win 8

    History:
    (most posters omit this)
    * Which build of Win 10 was running before you did a clean install?
    * Were you previously running 32 bit Windows and now 64 bit, or the same?
    * What led you to wanting to do a clean install- were you experiencing particular issues?

    Suggest you make a comparison when
    a. in Safe Mode
    b. booted from a live boot disk

    Hi dalchina,


    The KBD test was successful in the sense that all keys registered OK. Granted, some only after having to be pressed one or more times. I ran the test 3 times and problematic keys were random (Except that they were only letter keys).


    It's a rather old machine (2003). The machine had been running Win 7 Pro x64 with no issue since then.


    The BIOS is F.40 from 2013, the latest at the time. I know a newer BIOS was posted to address some security vulnerabilities, but, strangely, only for Win 7 and 8.x. So I didn't bother.


    I had to do a clean install since there was no upgrade path to Win 10. That's also why I had to search for drivers.


    I'll try your 2 suggestions and report here. I was also planning to test with another mouse and kbd.


    Thank you for your time.

    If Win 10 wasn't offered via Windows Update, that suggests there are known compatibility issues. There are no guarantees whatsoever of it running Win 10 successfully, of course. (I got the 2013 date from the date when it was reviewed... I searched for

    If 2003, maybe it's a different machine?

    Still, I would be very interested in getting an explanation as to how devices ' pointers could work seamlessly but not clicks. Or how using the other device could always restore usability to the first.

    Because not being able to understand a problem always blocks the path to finding a solution.

    You could be looking at very low level analysis of code behaviour for that if you were to do that analytically. You would need development debugging tools and access to the code.

    We are mere users, alas.

    By deciding to run Win 10 on a machine for which it was not designed, you take the risk, and it primarily rests with you to try to find a solution- if there is one.

    I'm not trying to pass the buck. But that's the 4th HP rig I'm forcibly converting to Win 10 + SSD, and it would have been nice to learn something new out of that failure.

    A day without learning is a day lost, they say. I fully agree with that.

    Maybe you know about some more hardware-oriented forum.

    Thank you for your time.

    You can still try this as I first suggested:
    Suggest you make a comparison when
    a. in Safe Mode (basic drivers used)
    b. booted from a live boot disk (proven Windows installation independent of anything you have installed- also Kyhi's as given is based on an older Win 10 build).

    I already ran a Partition magic Unix-based boot CD on it. No problem at all.

    I'll try Safe Mode out of mere curiosity and report back.

    Not surprisingly, Safe Mode didn't correct anything...

    Thank you for your reply.

    Of course Safe Mode would not fix anything, that's not the point at all. The question is how the mouse behaved by comparison in Safe Mode.

    I understand you're saying the mouse worked ok with a live boot disk.

    Now please try a clean boot and compare. (Google clean boot if unsure or see tutorial).
