I've been trying to figure out what's wrong with my 2012 13" MacBook Pro. It has proceeded strangely. For a while, I had...

This question is not specific to any particular device, unless bits of fabric are devices. I ended up answering it myself...

I get this sensation from everything electronic. It’s normal that replies to posts like yours will say “that is not possible,” but it is. I get it from corded and cordless mice, cell phones, iPads, all keyboards, all laptops. Charging, disconnected, grounded, not grounded. I haven’t tried grounding myself or discharging static electrcity as if starting a sensitive repair. I’ve seen posts in various online forums by other people with this odd and unpleasant problem, but never an explanation. To the best of my knowledge, it started in 2015. FWIW, I used to get a burning hot sensation inside my temple when talking on a cell phone. I don’t hold them anywhere near my head anymore.

This answer might or might not help. Unfortunately I will refer to a document I read online recently but failed to bookmark, so consider this is more of an introduction to a unicorn than an answer. Facing a similar problem with forgotten pattern and no clue which of many gmail accounts the phone was associated with, I tried every gmail account I could think of and admitted defeat. I halfway think there was a bug in my old Motorola's software that meant I couldn't have recovered access even if I did know the gmail address, but that's neither here nor there. Defeated, yes, but still breathing. I hate nothing quite as much as destroying data, so I did not want to do a hard reset. I decided to find out if smudges or fingerprints on the phone's screen might somehow carry a memory of the pattern I routinely used to log in to the phone in the past. I entered various search terms into Google and eventually found that some security researchers, possibly in Israel, had published a white paper on the topic. I was...

Thanks for videotaping this repair. Do you have a version that does not look like abstract are, though? I hate to complain but it is hard to make out exactly what's going on in this video.

were you vacuuming the solder that had to be removed?

What is the spec for the wire?

thanks for any illumination you can provide on these topics.

Here’s some “low hanging fruit” to get out of the way before considering the more mysterious possible causes. Do you have any Bluetooth input devices like a mouse, trackpads or keyboard in the vicinity of the computer? If such items are powered on, they can interfere with even wired mouse clicks. Remove their batteries and wait a few seconds and then see if your mouse works.

Dear Pierre:

I’m not able to envision a successful implementation of this step. I don’t have a bench vise handy so I can’t just mess around until it works. If the needle-nose pliers is just sitting on the vise, and I’m holding the adaptor, what forces the pliers to pry the case open instead of clattering to the bench? Got photos?

Steven, could you elaborate on your suggestion? I think you’re suggesting we use a spanner bit, which looks like a a flathead screwdriver with a notch in the center of its straight edge. But spanner also means wrench in British English, so clarification would be helpful.

Where is the near corner of th space below the clips. Could that also be described as “one of the side seams, right where it terminates and the depression that accommodates a tidy hook that’s not in use not in use begins”?
