Hi! In the guids of the macbook retina 2012 I cannot find a guide to repair some keyboard issues. Since some days some single keys (the 'm' for example) don´t react anyore. First I thought a RP-reset can help - the reset didn´t help, so it seem to be a mechanical problem and not a software issue. Maybe dust or something else.
Does anyone have some experience with that??
Thanks for your help!

Hi!
My batterie seems to be ok - what do you think?

Hi!
You never believe..! I found the problem! It´s not the batterie and not the keys are damaged. It was/is an software issue - so nothing to fix in this case.
It seems to be a high sierra problem I earned when I told my OS to ignore the built in trackpad when a mouse is connected. (I did this because of some Logitech mouse issues - suddenly no scrolling, because of safari safe mode on login sites..) This option caused in NO mouse as I was on the road..so my trackpad was ignored even if no mouse was connected..so I had to lend a mouse and switch of that option. What I didn´t recognise, that the option 'enable mouse keys' was switched on - not by me, but turning my 'm', 'L' and some other keys into mouse keys..thats it. This option should turn the nummeric pad into mouse keys and not the m, L,.. ;-) - i recognised this because the cursor was moving a very little when pressing the non working keys. Is adobe owned by apple.
Thanks for your help!! Nothing to fix, but good to know!
