I've got the same MBP here, same exact problem as these folks MBP turns off Randomly Without Warning Anyone been able to actually nail down the cause and permanently fix the issue? Mac os x lion amazon.
Or is this possibly something that Apple should legitimately be covering under a recall?

I'm on my laptop right now trying to reply to this thread - and it's shutting down on me just the same.
- Nov 08, 2018 Reset NVRAM or PRAM on your Mac If your Mac has issues related to settings stored in NVRAM or PRAM, resetting it might help. NVRAM (nonvolatile random-access memory) is a small amount of memory that your Mac uses to store certain settings and access them quickly.
- I remembered that the in most cases resetting the PRAM ( Parameter RAM ), PMU ( Power Management Unit ) and the NVRAM ( Non-volatile RAM ) usually resolves most issues when you think it might be something larger. In case you’re a long time users and forgot what the PRAM controls here’s a run down on how to reset Mac PMU.
If you’re having trouble with your Mac, resetting the PRAM might help. It is one of the most common troubleshooting techniques on the Mac. This article tells you how to reset the PRAM and also tells you more about what it is. You can reset the PRAM by restarting your Mac and holding down the keyboard combination Command+Option+P+R. How To Reset PRAM: To reset the PRAM, reboot the computer and hold the options-command-P-R keys at the same time. The computer will chime, and then continually reset and chime while these keys are held. Allow it to cycle a couple of times and release the keys and allow the computer to boot normally.
Sometimes I can't get more than 45 seconds after it boots up before it shuts off again. It's quite embarrassing when I go on site to a client and I'm constantly saying 'Hold on, gotta boot up again.'
I have also reinstalled, reset SMC, done everything I can aside from tear it down and check for any issues ..
Apple also says no problems at all. That's obviously not the case.
Unfortunately there's no diagnostic issues at all. We ran through everything mentioned above (except PRAM reset, see below), not one single anomaly. It's just, when the MBP decides 'it's time to die', I can't keep it running for more than probably 2 minutes without it completely shutting off. Typing seems to facilitate the problem, but even when I am using the unit through an SSH session, it still exhibits serious system failures.

2009 Mac Pro Manual Pram Reset Manual
As noted above, I had not reset the PRAM (only the SMC), so I did that this morning, and I am still waiting to see whether or not that is actually going to provide me with a solution. I only use the MBP when on site with clients. So I will know soon whether or not I have any success with this.
But it gets quite embarrassing in front of clients when I'm like, 'Yea, sorry, my $2,000 MBP doesn't work for more than 45-60 seconds at a time. Please excuse me while I reboot. Manual mac youtube. Also, for your recommendation regarding new workstations .. Probably, uh, I want to say Apple but I'm going to go with Dell.'
(No, I would never go with Dell, especially if they want Apple. But I embarrass myself, my company, and my Apple products when they perform at an embarrassing level.)
With our MBP from late 2013 (manufactured in 2014), we never had this problem until upgrading to OS 10.10. And since 10.11, and 10.12, it has become progressively worse. At my most recent client meeting I had to hard shutdown my laptop 17 times, lost vital notes from client discussions each time, and this was all within a 75 minute period.
Please reference my previous interactions with Apple regarding an issue I didn't believe was the cause/problem of the consumer, G4 PowerBook Memory lawsuit: https://laz.paravis.net/apple_complaint. Apple has a tendency to blame consumers before they actually acknowledge a problem that was a result of their own engineering deficiencies. Maybe it's to see what they can get away with, or maybe it's that their quality control needs a bit of a refresh. But the bottom line ..
Three years old (my MBP is about 2.8 years old) is not a legitimate period of time for a consumer product to exhibit 'normal wear and tear' and become completely unusable. That's just a joke -- barely outside of the hardware warranty .. https://newor663.weebly.com/mac-extendable-aluminum-trailer-repair-manual.html. And I take VERY good care of my hardware.
What are your thoughts?
I'm definitely going to update my post with my results after resetting PRAM, but to be honest, I don't expect that to be a fix. Anyhow, there are attorneys out there drooling from the mouth to sue Apple for the way they treat their customers. I love Apple, and always (probably always) will .. https://newor663.weebly.com/manual-martin-mac-250-krypton.html. But I'm not one who appreciates getting blamed for their own engineering mistakes.
Sometimes, that extra $0.04 per unit for a bump in quality for a particular metal alloy is really the difference between a product success and product recall.
I love your analogy about the cars. It really is like that. But my poor little laptop is used so rarely, I couldn't see it even needing a tune-up. I'll get the thermal paste and sort that out, as well as the potential dust-bunnies and see how it goes. I ordered the proper screwdriver but they sent me one that was far too small instead of the right size.
Thanks again for your reply, Dan. Have a wonderful weekend.
Update (12/04/2016)
I seem to have spoken too soon about a fix! Typing this from my phone, since the laptop won't stay working long enough to finish a proper sentence.
So back to square one .. Going to get the right size pentalobe screwdriver and check for dust bunnies and reapply thermal compound to the CPU heatsink.
Big issue though, but at least we have a new symptom! When I put it to sleep earlier this morning, the fans stayed on indefinitely (until I hard-powered off). They just kept blowing and blowing - and it was COLD air, not even warm. So overheating seems to be a bit of a long shot at this point.

I'll update again after I have a chance to open it up.
Bummer!
Is this a good question?
Comments:
Can you supply us some diagnostic data that would help. Go to the top Answer there you find a few different URL's to useful tools that can help in locating whats happening here.
Given the age of the system I would recommend doing a good clean and re-doing the thermal paste. Its quite a bit of work as you can see here in this IFIXIT guide: MacBook Pro 15' Unibody Mid 2009 Heat Sink Replacement we're reusing the heat sink only cleaning off the old paste and applying a fresh coat.
As to an Apple recall not likely to happen as this is a vintage system which Apple is not offering service any more (independent repair shops still are and parts are still available). Just like cars older ones need some TLC to keep them running as things do wear out and dry up.
Hey there Dan, thanks for the quick reply!
See my comment of my comment for more info (there is not enough characters allowed.)
Thanks again. This place rocks, by the way. :-)
I don't read legalize that well ;-}
Can you give us a synopsis what it was about. Also do you know the outcome of the lawsuit?
Is this the issue you where facing?: PowerBook/iBook lower RAM slot failure (revisited)
I also remember some people were confused on how the video used part of the RAM (which by the way was the common practice even with the IBM PC world).
The legal deal was back in 2005. Bought the last-generation G4 PowerBook, and after about a year or so, the second memory slot completely stopped working. They kept telling me I had caused the problem.
I think that's it in the link you sent. Apple agreed to issue a global recall of the mainboard without litigation.
It was actually pretty crazy though, because I didn't mean to even get involved in that lawsuit. I just posted on a forum somewhere (just like this), and the attorneys contacted me. And Apple sent me a first generation Intel MacBook Pro instead of just replacing the faulty hardware.
For my current issue, I reset the PRAM yesterday and, oddly enough, it has been working normal - no shutdown! Crossing my fingers it stays like this! :-)

I'm surprised to not really see a 'fix' for this problem. Quite a few posts about it, but no actual 'Ok, so here's the fix!'
I'll update in a few days as to whether or not I'm still good to go. But it's weird the PRAM may have something to do with it?!
I'm going to 'answer' the question, prematurely, as it's been MONTHS since I've been able to use the laptop this long before shutting off. I haven't even been able to get through sending an email or even writing a post on a forum ha ha ..
When your Mac starts acting up, you’ll probably run through some common troubleshooting procedures, such as restarting it, running Disk Utility, and perhaps performing a Safe Boot. Your repair repertoire should also include a couple of additional procedures that can occasionally eliminate otherwise inscrutable problems—zapping the NVRAM and resetting the SMC.
Zap the NVRAM (or PRAM)
2009 Mac Pro Manual Pram Reset Instructions
Back in the day, the standard list of quick fixes for random Mac ailments always included “zap the PRAM.” The P in PRAM stood for parameter (the RAM was just RAM—random access memory), and it referred to a small amount of special, battery-backed memory in every Mac that stored information the computer needed before it loaded the operating system. If the values in this memory got out of whack for one reason or another, your Mac might not start up correctly, or might exhibit any of numerous odd behaviors afterward. So you could press a key sequence at startup to reset (or “zap”) the PRAM, returning it to default, factory values.
Modern Macs no longer use PRAM; they instead use something called NVRAM (NV for non-volatile). NVRAM serves approximately the same purpose as PRAM, but instead of storing a dozen or more pieces of information, it now contains just a few: your selected startup disk, speaker volume, screen resolution, time zone, and—if your Mac has crashed recently—details of the last kernel panic.
NVRAM corruption is fairly uncommon, but if your Mac seems to take forever to figure out which disk to boot from, if it starts up with the wrong screen resolution, or if you have weird audio problems (like there’s no sound whatsoever, or the menu bar’s volume control is grayed out), it doesn’t hurt to reset the NVRAM—it’s quick and harmless.
To reset your NVRAM, you use exactly the same procedure you once used to reset PRAM.
- Shut down your Mac.
- Press the power button, and as soon as you power up the laptop, hold down Command-Option-P-R.
- Keep holding down those keys for about 20 seconds. Then let go and allow your Mac to continue starting normally. If you have an older Mac that chimes at boot, hold down the keys until you hear a second startup chime.
- Then check the Startup Disk, Display, and Date & Time panes of System Preferences to make sure they’re set the way you want them.
If you hold down Command-Option-P-R at startup and you see nothing but a gray screen that doesn’t change for several minutes—no Apple logo, no progress bar, no second startup chime—don’t panic. The most likely cause is that your Mac isn’t registering the key presses due to wonkiness with a USB device. Disconnect all USB devices (except your keyboard, if it’s a wired keyboard), hold the power button down until the Mac shuts off completely, and then press it again and immediately hold down Command-Option-P-R.

If that doesn’t work and you’re using an external Bluetooth keyboard, try plugging in a USB keyboard instead. If you’re able to reset the NVRAM successfully with the wired keyboard, you can disconnect it and go back to your normal Bluetooth keyboard.
Reset the SMC
Yet another component of your Mac’s hardware that stores crucial settings is the System Management Controller (SMC), a circuit that deals with power management, temperature monitoring and fan control, status lights, keyboard backlights, and a few other components. If your SMC becomes confused, you could experience problems like excessive fan noise, slow performance even though Activity Monitor doesn’t show the CPU being overtaxed, apps that take forever to launch, batteries that don’t charge correctly, problems with sleep or wake, and so on. (You can see a longer list on this Apple support page.) As with zapping the NVRAM, resetting the SMC to factory defaults may resolve these problems.
2009 Mac Pro Manual Pram Reset Key
Apple says you shouldn’t reset the SMC without first trying other troubleshooting tasks, such as force-quitting problematic apps and restarting your Mac. However, Apple doesn’t mention any negative consequences of resetting the SMC, nor any way to determine for sure if the SMC is glitchy without resetting it and noticing that the problem went away. I’ve reset my Macs’ SMCs many times with no apparent ill effects, and on occasion that did in fact turn out to be the solution to a problem.
Before you can reset your SMC, you must shut down your Mac. After that, the procedure varies depending on the type of Mac you have.
- Desktop Macs: Disconnect the power cord (either from the Mac or from the AC outlet). Wait 15 seconds and plug it back in. Then wait another 5 seconds and turn the Mac back on.
- Portable Macs with non-removable batteries: Shut down and unplug your Mac. On the built-in keyboard, press and hold the Shift, Option, and Control keys on the left side and press the power button and hold all of these down for 10 seconds, then release the keys. Connect the power adapter and then turn the Mac on normally.
- Portable Macs with removable batteries: Shut down your Mac. Disconnect the power cord and remove the battery. Press the power button, hold it for 5 seconds, and then let go. Put the battery back in, reconnect the power cord, and turn the Mac on normally.
Although neither of these procedures is a guaranteed cure, both of them can solve a number of odd problems, and are worth a few minutes of your time before hauling your Mac in to see the local Apple Genius.
