Macbook Pro 2012 A1398 not turning on

My Macbook Pro 2012 has been running fine as a secondary device just for some testing etc for ages...battery died a long time ago so it's just been running off the plugged in power cord...no major dramas. I do normally just leave it running or in sleep mode...I rarely turn it off.

This last weekend, I had it switched off from Friday afternoon. Tried turning it on last night – nothing. Tried a few key combinations online but still absolutely nothing. Used a different power cord...no good. I also resorted to taking the battery out and seeing if it would start while plugged in...all no good.

My question is, if I bought a new battery, what are the chances it would boot up or does it sound like something more serious? There is some data on there I'd like to recover, but it's not super critical.

If there's no chance of it ever booting up gain, is it likely all my data is gone, or is it possible to take out the SSD and put in an enclosure?

Thanks in advance.

MacBook Pro 15″, OS X 10.11

Hi

If you can't get the machine to turn on then it seems you might need to get an Apple authorised service provider to take a look. I had the 13" mid- 2012 until recently and it was easy to get to battery, RAM and hard drive.

If it was me, and that SSD is accessible, I would take it out as you mentioned, get the data you need from it (unless the drive itself has failed?!) and then pop it back again if you want to try a repair.

I assume no Time Machine backup for this one?

Good luck

If your MacBook Pro is not turning on, here are some steps you can take to troubleshoot the issue:

1. Check the power source: Ensure that your MacBook Pro is properly connected to a power source, and that the power adapter is working properly. Try connecting it to a different outlet or power adapter to see if the problem persists.

2. Reset the SMC: The System Management Controller (SMC) is responsible for managing power-related functions on your MacBook Pro. Resetting the SMC may resolve the issue. The steps to reset the SMC will depend on the model of your MacBook Pro, but you can find instructions on Apple's website.

3. Reset the NVRAM: Non-Volatile Random Access Memory (NVRAM) stores settings such as volume, display resolution, and startup disk selection. Resetting the NVRAM may help resolve the issue. To do this, restart your MacBook Pro and hold down the Command, Option, P, and R keys until you hear the startup sound twice.

4. Try starting up in Safe Mode: Starting up in Safe Mode can help isolate the issue. To do this, restart your MacBook Pro and hold down the Shift key until you see the Apple logo. If your MacBook Pro starts up in Safe Mode, it may indicate a software issue.

5. Check for hardware issues: If none of the above steps resolve the issue, it's possible that there is a hardware problem. You may need to take your MacBook Pro to an Apple Store or authorized service provider to have it diagnosed and repaired.

If none of the above steps work, it's recommended that you contact an authorized service provider for further assistance.

I ran it 90% of the time in Bootcamp Windows mode...so no Time machine. I do have backups...there's some work from the past few weeks I'd like to recover if possible. Not life changing if I don't...but just trying to work out the cheapest way at this point...it would seem like this machine is probably dead?
