    Default FN / CTRL-Key Switch Mod

    Hi!

    I finally did it. In Hardware. Switched the positions if the FN and CTRL key.
    Here's a little how-to:

    Things you need:

    Silver conductive paint/lacquer
    Sharp knive
    a little bit of clear sticky tape
    small paper clip



    The key on the down left should be CTRL/STRG and not FN. Don't know why Zepto did that.

    So lets begin... first take out the keyboard from the notebook (use search in this forum, was already discussed)



    gently pull out the key caps (just lift em up at the front a little bit - be careful, its just small plastic!), then use a small paper clip to disassemble the key-"mechanics".

    i disassembled the following keys: FN/CTRL/Win/ALT/SHIFT/CAPS LOCK/A/Y

    reason why i did this is, you need space for lifting the keyboards layers.

    you should end like this:


    as i am always pissed with hitting the caps lock key by accident (instead of shift) i just disabled this key (i never used this key in my whole life, so what!)



    i just sticked a small piece of tape between the 2 contact layers (my keyboard has 5 layers)



    now lets go deeper and take a look at the different conductive layers:





    as you can see, 2 contacts/keys are going to one circuit path, i call it GND. now take the other conductive layer.



    now here comes the tricky part, cut off the 2 circuit pathes, as shown. do NOT cut the plastic itself, just scratch the circuit path off the plasticlayer.



    now gently remove the greenish cover, to get to the circuit path itself. once again be careful! do not cut the path itself, just the green protecting paint.



    now its time for the silver conductive paint (shake before use!).
    draw a thin line of silver conductive paint as shown on the pic (red line).
    let it dry. let it dry. let it dry. its only conductive if its dry, if you go on too early you will easily smear the silver around (i know what i am talking about )

    then, after drying, use sticky tape to protect the new circuit path (just put some tape over the silver line, to make sure it has no contact to other layers). after that, you'll have to repeat this step with the other 2 conductive pathes (shown as the green line). once again, let it dry and then protect it with a small strip of sticky tape.

    do not cover the wholes, you need them for reassembling the keys! i painted the "green" silver line directly on the protective tape of the "red" silver line (not shown).

    now reassemble your keyboard and put it back into your laptop. keep your fingers crossed that all neccessary conductive paths have "contact".

    turn on your laptop, wait for booting up and if you did not make any mistakes you finally end up like this:



    nice and clean, working perfectly, as it should always have been.

    note:
    i am not be responsible if you destroy your keyboard when trying this!!!

    hope this doc is helpful.

    this mod should work on any keyboards with plastic layers. its not just zepto related.

    if you have any questions, feel free to ask

    bye,

    Thank you for this update.

    I am impressed. I've never gone that far in disassembling a keyboard. However, I don't think all keyboards are build the same way. I have just looked at an old Fujitsu notebook keyboard and that has a plastic layer below the keys which is fixed through holes in the metal base.

    The Fn key in the corner is an atrocity, I think we can all agree. You are a man among men for righting this wrong. I salute you!

    this trick works on some desktop keyboards too. sure, not ALL keyboards are suitable, but i think most of the el cheapo ones will work.

    yeah, it could be done in software but in hardware it has only advantages... no need for software, you can easily reinstall windows/linux/whatever. no need to fiddle around with key switching software.
    i still don't get it why zepto has switched the keys...
