They bypassed the AppleID and sped through setup and ran hardware tests. Next I made an appointment with the Genius Bar. Coming back in to re-do the setup it started crashing when setting up the wifi connection. During the re-install setup steps it would crash when I would enter in my AppleID information. Next I reformatted and re-installed High-Sierra. He had me re-install High-Sierra over the top - no fix. Anyhow, I hope this saves someone a lot of hassle. I think that is why on a cool start it would certainly last me longer, but in the end I could tell it was overheating, but buy no means would I believe the board was bad as the computer always returned to good working condition once it cooled. But with dry paste the heat can’t displace properly causing it to overheat. I believe the machine is shutting down because it is overheating, it has a built in safeguard to stop it from becoming damaged. So because I needed to get back to work and was tired of ordering parts, I cleaned it up, put the paste on and installed the old board.
The paste on the old board was dry and cracked. The more I thought about it I realized one major step in replacing the board is to remove the thermal paste clean it up real well, and apply new paste. Frustrated I put the whole computer in the closet and decided to give it a break. I got my matchbook pro 15” 2.3 dual graphic 16 gm ram all taken apart to realize I had accidentally ordered a logic board with integrated graphics. Got the board and opened up the guide to start the tear down. Read through all your past posts and figured I Best Buy me a new logic board. Why even bother to offer that kind of service? This means I'll have go with (an independent) logic board repair (350€ max). I found some independent site which replaces RAM only for 100€, let's see how that turns out.Įdit3: Well, big surprise: They'll actually return my device right away, since RAM is (very obviously) soldered onto the logic board. Treatment is the same though: Replacing the whole logic board for 650€.
They found out that the crashes relate to a defective RAM module. Great job, guys! Now I have to decide whether to sell it broken or repair it before selling.Įdit2: Brought it to an Apple Store for a second opinion. So, they offered to replace the logic board for 800€, uncertain that it will even resolve the problem. Even when they replaced the AirPort card with a new one, the crashes would persist, suggesting they had something to do with the logic board.
They couldn't reproduce crashes when connected over Ethernet. They diagnosed this to be an issue related to WiFi. In fact, my MBP crashed twice while writing this answer.Įdit: Brought my MBP to an ASP. Fixed the issue and the notebook has been working with no problems so far. It was dry and cracked, so I bought some Arctic Silver MX-4, cleaned the old paste and put the new one. For example, if I ran an html game on Chrome (with hardware acceleration enabled) and that switched to the discrete GPU, after 5 minutes and closing the tab I would get the freeze almost every time.īefore going to the Apple Store again and be told that the logic board needed to be replaced, I removed the heatsink to see the state of the thermal paste. Things got worse and I noticed the crashes were happening when the notebook switched from the discrete to the integrated GPU (used gfxCardStatus for that). I installed smcFanControl and that seemed to alleviate the problem. I needed the machine and the freezes weren't that often. Took it to the Apple Store for a diagnostic and everything seemed normal to them, although they offered a continuous test during several days, which I declined. I had the same problem, notebook freezing and after a few seconds a black screen (most of the times a regular shutdown).
Short story: check and replace the thermal paste over the CPU and GPU.
