Is there a liquid contact indicator (LCI) underneath the G key?

I recently bought a defective aluminum Apple Wireless Keyboard for experimentation.

Model A1314 with Dashboard key on F4

Some keys spread over the whole keyboard did not work.

I put it in the dishwasher (with soap and rinse aid at 45°C for 40 minutes) and rinsed it generously with isopropyl alcohol while it was still hot after the wash.

(right now it is still in the drying phase.... keep you updated how it worked....)

->update: The keyboard turns on and I can connect to it and type, but the non working keys still don't work.... no succes here.<-

Right now I discovered a red spot underneath the G cap and took it apart.

I did not look before the wash, so I cannot tell if it was like this before.

Is this thing you can see on the photo a LCI like Apple mentions?

I could not find any other information that there are LCIs built into these keyboards. Maybe somebody else can check on a non defective/liquid spilled keyboard.

In my case the red dot can be spotted with the keycap on.

But you can take the caps of quite easily with lifting the caps up very carefully starting at the upper right or left corner. It comes loose with two or three clicks and is quite easy put back into place with clicking it back in in reverse order.

This in an old thread but I have kinda the same problem so thought to refresh it a bit. I bought an iMac with it’s accessories more than a year ago. Well I didn’t have luck with them, turned out the guy f***ed me over big time and sold me a half dead iMac and keyboard (at least the mouse works haha). But that’s the end of the story.

On my keyboard (A1314 ) Tab, Caps lock, Fn, and Space keys aren’t working. I took off these keys yesterday and I saw a nice red dot under the Caps lock key. So after I saw this thread I took off the G key too and saw the same indicator (LCI) kinda white. So I guess you were right 2000one and those are indeed Liquid Contact Indicators. I gonna take apart the whole freakin’ keyboard today and check out if I can do something and also check out first if there are other LCI-s underneath the keys so I’ll know which part of the laminate I have to “resolder”. Fingers crossed, it’s gonna be a tough job…

There is a guide on this site about how to take apart and fix a A1314 keyboard without destroying it, I gonna follow that one.

Thank you Transistor Girl! Now we know that liquid damage could be spotted before purchase of a keyboard like that. Hope your project goes well! Take care :-)

You too 2000one ;) I haven't found any more LCIs, so if anyone buys this one, check the dots under Caps Lock and G! You can avoid what happened to us ;) Because this keyboard...I know why it's called Magic keyboard now :D It's a Magic that they can sell these for this amount of money :D Engineering of the century LOL.

Thanks. Did I miss something about the LCIs in your teardown??

Your answer is not referring to my question or the A1314 model --> not helpful...
