Question

Macbook Pro shutting down. Hardware error code 4MEM/62/40000000:0x7f537f90

Macbook Pro shutting down. Not the same action making it shutdown. Anywhere from being online to attaching a photo to an email to working in Word or Photoshop. Even after it's closed and not being used. I come back to it being shut off and saying it had to restart because of a problem. I ran the Hardware check and got the Hardware error code 4MEM/62/40000000:0x7f537f90.

I must say I am quite disappointed. I have used Mac for work but had a PC since day one, and I JUST got this Macbook Pro in Dec. I was delighted that Mac usually didn't have as many problems with viruses etc as PC. And now last couple days, constantly shutting itself down. The closest store to me is a few hrs away. I am in South Dakota, store is in Minnesota 😟 Any help would be appreciated.

MacBook Pro, OS X Yosemite (10.10.2)

Can you run Apple Hardware Test? You may have bad RAM.

I Did online chat just now. They said same thing. And to first try a reset by doing Command+Alt+P+R at startup. Does that do anything? If not an hr trek to the closest certified repair shop. How does RAM go bad on a new machine anyway???

On newer Macs, the RAM is soldered and it could be that there is a bad solder, or could be loose.

Apple Support is asking you to run an SMC reset - Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support . If ti is a hardware issue, SMC Reset will not help, but it is worth trying at least once.

Does bad RAM cause weirdness like this? It kept starting and shutting itself off repeatedly. Then I opened it up to this. After restarting it went back to normal. Just wondering if there are other issues besides bad RAM. Taking it in tomorrow 😟 I switched to MAC from PC to get away from problems darn it!

Can you post a screen shot of About This Mac -> (More Info) -> System Report -> Memory and click on each DIMM and post the bottom right pane. You can also do the same without a screen shot using just text version using the following highlighted command in OSX Terminal. The output is also listed.

This is Hynix memory - HMT451S6AFR8A-PB. It is very unlikely that the RAM is bad.

Can you look at https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Unibody+Mid+2012+RAM+Replacemen t/10374 and re-seat your RAM?

If you connect an external display, does it also show similar behavior?

II'd love to try that, but since I just bought it a few months ago and the hardware warranty is still good. I don't want to mess with it. it would void the warranty 😟 if it isn't ram any ideas? Since,the code it's showing says a ram issue? Could it be more than just that?

This looks like a hardware issue. You may want to make a Genius Bar appointment with Apple.

Upgrading your RAM should not alter AppleCare. Apple has their own instructions for it - MacBook Pro: How to remove or install memory - Apple Support. If you do not want to make changes or open the case, an Apple Store or an AASP can help.

Apple support was asking you to reset the NVRAM, not the SMC:

https://support.apple.com/en-gb/HT204063

If no success, take out the modules and clean the contacts and reset them. Make certain that they are well seated. Check to see if the RAM is recognized.

If still no success, download Rember from Kelley Computing and run it overnight (assuming that the MBP allows you to do that). That way sufficient loops will be executed.

Last option is a visit to an Apple store genius bar for a free evaluation.

Ciao.

OKay took it to get looked at. They did a quick scan as they were checking me in. Said hardware is showing fine. But if the hardware test shows the above code, and Apple support said possible RAM, how is it showing up fine? I'll find out the verdict Monday. :/

OOk here is the latest. They had it all weekend. When I talked to them last night it hadn't shut off. But when I picked it up this morning they said it did crash and that they replaced the RAM. I get it home, and now I can't get it past the load screen. It gets halfway and shuts off. Are there any commands to get me past this point? Contacted the repair guy. He said it was fine this morning. I picked it up, drove the hour home and turned it on. So not sure what is happening.
