MBP 15" 2015 random shutdowns

[Marcus592]

Hello,

I have a 2015 Macbook Pro 15" with MacOS 12.6.8 and I have been experiencing some problems for some time. When I finish using the Macbook, I close the lid and disconnect the two external monitors. The problem is that the next day I always I find it turned off, but it is at 100% battery. Also, sometimes while running, it freezes and I have to force it to shut down. Is there any way to diagnose if it is a software or hardware problem?

Thank you.

I saw that in the Console there are some logs in the minutes the last crash happend, something that i can check there?

First, I would try to update Monterey OS to the latest 12.7.6. Your version 12.6.8 is a bit old and if I remember correctly, 12.6.8 had a few issues with sleep & shutdown that caused kernel panics.

Now updated and still crashing

If you disconnect BOTH displays, and run the MBP that way, will it still crash?

If no, reconnect ONE display and try that for a while.

Then, substitute with the OTHER display.

Process of elimination to see if the displays/cables are impacting things...

Issues such as drive and heat can cause intermittent shut downs or crashes. Are you able to keep an eye on the temps within and health of your drive? If the frequency is high, with the older OS you could have gone into safety mode and with patience check to see crashes occur by running possibly some scripts to engage the drive and CPU. The latter is see possibly if some app is causing an issue. Other item, being an older laptop, as related to temp - fan should be checked and is the problem happening with the laptop open or shut and hooked up to a monitor? If the latter, sometimes heat can build up and more so on older systems with air flow slowly deteriorates due to dust and more collecting. Try leaving it open and see if it happens with the same frequency.

Sometimes, i leave the macbook without any screen attached and the lid closed, and when i open it the next day, it has shutted down due to a crash.

I'm always monitoring the temp with 'Macs Fan Control' and i recently opened the laptop and cleaned the dust inside. The temperature when it crashes is not so high. I think maybe it's an app but i don't know if there is a log that can be interpreted in order to know who causes the crashes.

Thanks to both!

As painful as it sounds, make a copy of all your data then reinstall the OS and start there then add applications back in slowly (you may need to make sure they are engaged). Also have you checked your mem with the activity monitor to see what is active?

Marcus...

I realize this reply won't "solve" your problem, but...
... have you considered just turning everything OFF at night, and rebooting in the morning for "a fresh start" ???
