Swift 3 SF314-54 keyboard problem potential solution

Problem description

Hi all, just wanted to share a potential fix for this infuriating issue where certain keys do not work (a,x,c,n). I had tried removing the driver and restarting multiple times which didn't work. Also tried changing settings (in the latest BIOS) and using the battery disconnect pinhole. This issue had persisted through Linux and Windows installs too so it obviously isn't an OS problem. The keys would sometimes randomly partially start working if I spammed the malfunctioning keys individually.

My solution:

With caution, press down firmly on the laptop, just in front of the keyboard, on either side of the touch pad such that the brushed metal flexes down.

This restored proper functionality for my keyboard. Not an ideal fix, probably not even permanent, but hopefully this can help someone who doesn't have the option of waiting/paying for a service.

    Hi all, just wanted to provide an update on this. Got sick of having to press down and bend the laptop and it seems I have found a permanent solution.

    I decided to open the laptop back up after reading the following threads: Swift 3 won't turn on. Swift 3 KB Degrades.

    Upon opening the laptop, like other times I couldn't notice that the keyboard cable was in any way damaged or inserted wrong, as the white line was as far in as I could get it, and seemed level/flush with the port. The user in the second thread I listed gave a good image, A and B are little plastic tabs you pull out to release the cable, while C is the battery cable:

    From my issue, it seemed that somehow, one of the pins for one of the conductors in the keyboard's flex/ribbon cable wasn't contacting properly in the port, and pushing down like I described in the OP made proper contact temporarily.

    I did the same as the user in the second thread, disconnecting the keyboard and battery cables, and then putting the battery cable through the keyboard cable (KB cable loops around 180), instead of over it. I then also got a small length of electrical tape and wrapped it up into itself to form a soft tube (adhesive on inside), but I'm sure some foam would do the trick too. I placed this soft tube inside the keyboard cable loop, such that it pushes the keyboard cable into the port firmly. I also added some electrical tape running horizontally from A to B (above) to hopefully hold the tabs and cable in a little better. If you use electrical tape you might want to consider using a type that won't leave sticky residue everywhere.
    As you can see, the electrical tape is putting upward pressure on the keyboard cable at point A. This seemed to fix my problem, hope it helps! Let me know if more explanation is needed.

    Have you tried opening the notebook to see if it is a badly docked cable? This is the inside of your notebook:

    I have poked around inside before, but couldn't recognise any cables that were improperly connected.
