⛔★ Key letter E not working right, lags 1sec :-(

[supak111]

Letter E on my keyboard only works if I push it down and hold for about 1/2 second but then it type like 15 E's: eeeeeeeee. I can also clearly see that it lags, so even after I let go of key E it will continue typing it for a second or so after. It does however always work I just have to hold it for 1/2 second leading mee to believe that it is not hardware reeelated.



All other keys work perfect with no lag. Everything else works on my late 2013 MBPr 15", no water damage, never been dropped, no new software, OS X up to date. Tested in SAFE mode, and in GUEST user but problem still there. Also did a SMC and PRAM reset :-(



HEEEEEEEEEEELP

Try turning the MBP upside down and tapping gently with 2 or 3 fingers on the base, and at the same time turning the computer left/right, and forward/rearwards. This may release a crumb or some other foreign body which has become trapped under the key. Also try a blast of air from a cleaning aerosol.
Failing that can the key not be prised up with a finger-nail, cleaned out and re-fitted? Must confess never tried the latter with my MBP.
Edit: Just seen that the keys on MBP can easily be removed by pulling down from the top with a finger nail, until it snaps out. Check out the on-line link "How to remove and clean MB Pro keyboard keys" which details the procedure, especially how the plastic underkey feature unhooks and it's re-fitment.

Just tried moving in all positions and tapping all over, still nothing. Also just cleaned the keyboard really really good with an air compressor too and it actually got worse.

I even took off the E key and cleaned under, and cleaned under the little rubber cup thats under the key part that actually push down onto the circuit board of the keyboard but still same issue. I don't get it. Could by keyword be bad? I just dont understand why only E

After reading about others having similar issues with other keys after even a slightest amount of water getting on their keyboard i think that i might have a damaged keyboard.

Do not recall ever getting even a few drops of water on it however. Keyboard is $20, I'm confident I can replace it myself.
