Does anyone have solutions to fix this error of AXCFN not working. Only works sometimes if I repeatedly press on each individual key several times. I’ve tried battery reset and uninstalling then reinstalling the keyboard it still didn’t fix the problem. Been happening for about a year now and laptop is about 1.5 years old only.

    Do the keys work correctly with an external keyboard plugged in?

    Then it's likely a hardware problem with the keyboard. The keyboard has multiple layers of film with contacts under the keys. When you press a key it pushes the contacts together and he matrix formed by that contact tells which key is pressed. If there is a crack in the traces that run between contacts you won't see any of the keys that use that trace. It typically show as several keys not working. If you are still in warranty contact Acer support for a repair. If out of warranty let us know (include your full model number) and we'll look up the part number for the keyboard. I the mean time, the external keyboard is a work around.

    Was reading this article which had the same issue, should I attempt to fix it to this solution?  https://community.acer.com/en/discussion/572185/swift-3-sf314-54-keyboard-problem-potential-solution

    Also the same keys not working (a x c f n) do work if I repeatedly press down and at other random times

    It certainly wouldn't hurt to try that solution. My next step was going to be trying to reseat the cable in case one contact was fighting a little corrosion.

    Can you please provide some more explanation maybe step by step with visuals. I am completely new to this and would like some further guidance given I have no experience

    Let me see if I can condense it a little:
    You might be able to skip the actual battery pack removal if you can access the keyboard connector after removing the adhesive tape. Reverse it all to put it back together...

    Thank you for providing a detailed explanation, how should I go about removing the battery cable?

    Once you have the tape holding it in place off you should be able to just pull it off. I usually use a couple of the picks used to disassemble phones and laptops to pull on each side of the connector, but fingernails would likely work as well.
