MBP 16" 2019 CRASHES WHILE SLEEPING

I have this problem ONLY when MBP is connected with docking station via Thunderbolt cable. Docking station is used for Ethernet cable, external disk and monitor. I suspect it could be somehow depended.

I spoke to Apple yesterday via chat. The person I spoke with made me run a first aid checkup on all disks. Then they recommended that I re-install the OS (BigSur). I said the OS was a fresh install. She said to then monitor and should it happen again to bring it in to an Apple store. In the meantime, Apple stores ae closed her in Montreal due to Covid. So, to try to remedy this I searched Google. If found this https://www.imore.com/some-16-inch-macbook-pros-are-restarting-when-asleep-after-installing-macos-10154-heres-fix. I will monitor and see if this helps as the computer crashed again this morning after sleeping all night (Sidenote: My 2012 MBP i7 & 2015 MBP i7 can last days w/out having any issues close to this!).

Hope this can help some of you that are having this issue. I'll keep you all posted.

node_pl you are right. I turned Power Nap off yesterday. Used the Mac as I normally would, which was not very much considering it was New Year's Day. Opened the lid this morning and it was (as it is too often) frozen. It proceeded to lock up with the keyboard then trackpad becoming unresponsive then the fans kicked in with a high whizzing sound, then it shut off and restarted.

Upon restart, I had the famous "Your computer restarted because of a problem...".

I will proceed with Apple now to see what they can do. Most of you should have these under Apple Care still...you ought to bring them in to local Apple stores to let them know there is an issue.

Thank you guys for the update above!

Here is some updates from my part.

After trying to enter safe mode, it seemed that the problem was solved on my case. Nonetheless, after a few days after upgrading to Big Sur 11.2, the same error happened again when I countered crashes when trying open Epic Store apps (everytime I tried to open it, it crashes) . Thus I had hold the power button again to force shutdown then re-entered Safe Mode again. Will try to see in the next few days whether the app Epic Store is the reasons behind the crashes as I have uninstall the programme.

Will keep you update as soon as I see the results.

Crash returned even with a fresh install (only happen if it is plugged in to an external monitor, in my case). We have to wait for a patch to fix this, hopefully ( MacOs Catalina 15.5.5 is coming)

turning off seems to ”help” the problem. I was having crashes every single time it went to sleep. Now its more like 1/5 times. Still annoying, but slightly better...

The only thing you can do now, I’m afraid, is to remove any screen/Mac standby timer in power settings.

And shutdown overnight.

Really disappointing for such a premium device...

Did anyone of you tried this in safemode? I tried safemode and had no crash. But I had a crash in normal mode even with just a usb-c dongle and a canon camera on it...

Seems like you are having hardware issues, not software problem.

have you tried with the Apple USB-C to hdmi adaptor, then directly to the monitor, without passing through an hub?

Im on MacBookPro16,1 2019 macOS Catalina v 10.15.5 (19F101)

with power nap disabled for both battery and plugged in power profiles

Yes. I con confirm above. In my case it only happens when I leave my Mac connected to the Lenovo docking station. It is now happens not very often but still I have this problem.

OK thanks.

Mine crashes with or without an external monitor. Mine seems related to any USB-C accessory being attached. I am using a Caldigit TS3 dock. I moved the monitor from the dock, to its own direct USB cable and port. Still crashes. Removed external monitor entirely, still crashes.

Ive disabled Graphics switching, Power Nap, neither of those things have had an effect.

Without any USB-C accessory attached it seems fine - but ill need to retest that again today been a week or so since I tried removing every device.

10.5.5 had a second beta released 16th April but no idea if this is being addressed in the update. Personally I cant install a beta i need my machine for daily work so cant risk testing it.

I have the same issue on the my Mac book pro 16. During the first two months it wasn’t quite often - maybe 1 crash in a few days, maybe once a week, but now it happens 1 or 2 times a day. I took my Mac to the service center and they made hardware tests and ensured me that problem was with the software. They did reinstall the software and told me to drop power or nvram to solve the problem. Most often Mac crashes when exiting the sleep mode with by the mouse move, or on any keyboard event, but now it’s been lagging , and then crashing while I’m working. The Mac support advised me to reinstall OS but it didn’t help.

The cable coming from the 20" Cinema Display is fixed from the Display. I did try changing the USB-C to DVI adaptor to another one and yielded the same results. I agree to always check cables but in this case, all is well until the external monitor is attached and the MBP16 lid is closed. I don't know the absolute solution but this is what I've done to eliminate the sleep-crash-reboot routine.
