Apple Samsung SM0512G (note: G-Type! Model IDs MZ-JPV5120/0A4 and MZ-JPV512S/0A4). Apple Samsung SM0512F (so again F-Type Model ID MZ-JPU512T/0A6) - sudden shutdown pattern on each of them. Did blank out after a few seconds, fans spun up, followed by shutdown shortly thereafter. The MacBook had an Apple Samsung SM0256F (so an F-Type Model ID MZ-JPU256T/0A6) installed when bought. but then of course lacked the Thunderbolt Ethernet).

I bought a bunch of 512 GB Apple Samsung SSDs last week for resale, of which one was intended to be an upgrade for a 'random-shutdown' MacBook Pro Retina (15' Mid-2014 it worked OK with the Thunderbolt-Ethernet-Driver removed. Mine has seen very heavy use for 3 years. I'm not replacing the logic board! I'll much sooner sell this thing for parts on eBay and buy another lightly used one. I'm not optimistic that either of these will be the solution that works. I am trying to meet deadlines for my Master's Thesis, which is why I'm posting this now, instead of waiting until after my Apple Store appointment, or waiting until after my battery cycle experiment. ran D diagnostics at startup, it found no problems discharged battery to 1% twice using Safe Mode.Д¤.

reset NVram/pram and reset SMC through various methods, including the official method (10 second hold with charger unplugged), and including disconnecting battery and holding power button for 2 full minutes.ДЈ. erased hard drive, reinstalled OS X, updated completelyДў. It seems I was reading solutions that maybe don't apply to my particular MBP. So I'll try it again in not-safe-mode after I get it to 100%, but I'm not optimistic that the problem will be fixed. seems I had a couple shutdowns while using Safe Mode too, but I can't really remember. Sorry I don't remember if Safe Mode completely fixes this problem. I was able to discharge the battery twice to 0% using Safe Mode.

Temperatures look fine using Hardware Monitor. Sometimes it happens once every hour, sometimes it won't even let me log in. Sometimes it happens at 100% battery, plugged in or not plugged in to the original Apple recharger. Seemed to happen a lot around 60-70% battery. When using the battery, it seems to happen more often, but it doesn't always happen when using the battery. The keyboard light stays on for maybe 10 seconds, and then the computer turns off.

The screen goes dark, but there is still a glow to the screen. It isn't really going through a shutdown sequence I don't think, as there is no 'dial'. About 5 days ago, I started getting random shutdowns.
