Followup: New , to me, MBP in the house, but ... - nwyaker - 02-03-2017
Mid 2012 15 MBP, 2.7 GHz, 16 GB, 1 TB nearly pristine cosmetically, but SD card slot and mic port not functional. Yeah, I know I can use external USB card reader and a USB iMic as workarounds.
I have visually inspected and cleaned the ports with air, tried different working SD cards and headphones, reloaded OS, etc.
Card slot is seen in Profile. Internal mic works.
Since those two ports are adjacent, I'm wondering if a bad solder or wire connection in that area on the logic board ?
Will be disassembling to install an SSD and taking a look then.
Any ideas ?

Reset SMC?

Frankly, I'd sell it right now. Adjacent ports not working is good sign of liquid damage. Corrosion tends to get worse over time.
If the price was low enough then keep it, but be wary. But that is such a rare thing you have there... demand on the 2012 2.6GHz is HIGH - there aren't very many 2.7GHzs.

"liquid damage"
I didn't want to go right there, but yeah.

We'll see when I get inside. Have worked on some with liquid damage, but this doesn't feel like it.
I hear you about the 2.7's.

If the device shows up in the System Profile, then my immediate suspicion would be the driver.
Did you install a clean OS on that Mac when you got it?

One of the first things I did.

Device-detection is more likely a PRAM issue than SMC. I assume that you've zapped PRAM, too...
Is there drop-damage on that Mac's case?

PRAM reset also. No drop damage - not a scratch on it, anywhere.
