MacBook Pro mid 2015 starts and shuts down immediately

Hi,

I have an issue with my Mac where it shuts down automatically within 5-10sec of boot. It started out very randomly. There is no physical damage or water damage.

One thing i noticed is that as soon as i press the power button, if i press and hold any other key(Enter/command/option/control/ESC) the laptop boots and works as usual without any issues. However, the key must held/pressed down through out the session. If we stop holding the key down, machine turns off automatically within 5sec. I have tried reinstalling OS, disk utility, safe mode and nothing fixed the issue. I visited an apple store and the technician ran all diagnostics and confirmed that the machine seem to be running fine and the issue and its workaround are something he never encountered before. He mentioned the issue 'could' be the logic board and replacing the board might fix the issue.

I was wondering if any of you have encountered this issue before or even have an idea of might be causing this?

Device info: MacBook Pro mid 2015, Monterey

Thanks

MacBook Pro 15″, macOS 12.6

Hello reneklol,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are unable to get your Mac to startup as expected, as it shuts down after a couple of seconds. To help with this, please make sure you follow these steps:

"1. Check power connections

Make sure that your power cable is undamaged and plugged securely into your Mac and a working electrical outlet.

If your Mac has no built-in display, make sure that your external display is connected to power, connected to your Mac, and turned on.

2. Press and hold the power button

Press and hold the power button on your Mac for about 10 seconds. (Every Mac has a power button. On laptop computers that have Touch ID, press and hold Touch ID.)

Then press and release the power button normally.

3. Unplug accessories

You could have an issue with one or more accessories or their cables. Unplug all accessories from your Mac, including printers, drives, USB hubs, and mobile devices. Then repeat step 2, above.

4. If you see something on your screen

If your screen shows a flashing question mark, circle with a line through it, or anything else, your Mac is turned on but isn't starting up:

If your Mac turns on but doesn't start up all the way

5. If you see nothing on your screen

If your Mac seems to be turned on but the screen remains blank, the issue could be software related:

If your Mac starts up to a blank screen

6. Reset the SMC (Intel-based Mac only)

If you're using an older, Intel-based Mac, resetting the SMC might help:

Reset the SMC"

And those steps are from If your Mac doesn't turn on - Apple Support

Cheers!
