MacBook Pro mid not responding to Power button

Hard to say, but may be a problem with the internal drive, but there are other possibilities such as bad memory (or bad memory slot), or a power issue (battery, charger, etc.). Try running the Apple Diagnostics to see if any hardware issues are detected. Unfortunately the diagnostics rarely detect issues even when one exists, but it never hurts to check.

Are you actually booting into Internet Recovery Mode? Try to force Internet Recovery Mode by using Command + Option + R immediately after hearing the startup chime.

I do have another option for creating & using a bootable Linux USB stick. I can provide instructions if interested if none of the previous suggestion help or provide any clues.

Yea I have all most the same problem I have the same MacBook and I think that the EFI is coruptes because the fans are in full speed and is so so slow... In the Administrator Task There is a process that it consumes all the computer try to do a NVRAM Reset and a SMC Reset...

The disk and the ram are from a laptop with a good history and a good record. It worked when I removed it from it. It’s the exact type of ram which is needed in this model of the MacBook. I will try the SMC and PRAM reset and update you if that works. Thanks

Was that memory from another Mac or a non-Apple PC? Memory from a regular PC may not be compatible with a Mac even though the RAM speed is the same since there are a lot more memory timings that are not usually listed on the memory modules and Apple certainly does not list those other memory timings in any documentation that I am aware. I have personal experience here and have seen numerous posts on this forum as well. I will only ever use memory that is actually listed as Mac compatible and then I will go with memory from Crucial or OWC.

As I mentioned in my first post within this thread, there are a lot of possibilities for the problem, but people must take the first step & start troubleshooting by trying my earlier suggestions to start gathering information that may help to narrow down the problem. I have a lot of simple tricks in my bag to figure out the problem, but we need to start gathering information by answering the questions in my earlier post so I know where to focus next.

Did you try to change the disk? And the ram?
