MacBook Pro 15'' touch bar A1707 4 ports 2017 Not tuning on

Also broken keyboard

Ok long story, many things went wrong at the same time please help!

I have an old Macbook pro 2017 with touch bar. 15 inch A1707. 4 ports, bought in UK in 2018.

It was one of the models with problematic keyboards Apple had recalled, but I totally missed the memo since I had already a newer mac I was using for work. So I had the old one for movies and photo editing and was using with a wireless keyboard so I never bother fixing it!

Now a few months ago, I was watching a movie while also running out battery and I had just started charging it. Somehow I managed to drop the laptop while it was playing a movie on low battery and with the charger on, I dropped it from the sofa to the floor about 40cm height. After that it turned off and never turned on again

I have tried charging with various chargers, connected to external screen nothing. no backlit, no sound when I connect the charger and no other sounds and signs it's alive.

The bad news I guess is that something broke / the good news is that it might just be a cable or software issue.

The first thing I would try normally is a hard reset and all the other keyboard combinations - if I had a working keyboard! Now that my keyboard is not working what else I can do?

From what I understand when the mac is turned off there is no way to connect a wireless or cable keyboard to it. Or am I wrong?

The touch bar was working before drop but now it is also black. And I don't see any physical damage after the drop

Is my only option sending it to service? I also live in a country without an applestore so FML

should buy a bunch of ifix it screwdrivers and try to disassemble it myself and check if unplugging the cables can make it turn on again? I never disassembled a mac myself but I can I can read online and do it step by step I guess.

Is it too risky to try it first time myself?

Is not worth the money to fully repair but I do want to turn it on to access the files I had in that hard drive.

Please help with any ideas what I should check first. From what I have read so far, There might have been a failure in the cable?

Not really enough info to isolate out what is damaged. Ideally I would plug in a USB-C meter in-line with the charge to see what the charging logic told us.

Sorry to say this is not a software type of problem. While a bit of a Hail Mary, the Power Pads won't likely help you here. Unless the upper case got damaged around the power button. If you feel a small resistance as you press that's the blister button depressing which is what the Power Pads emulate.

Here's the backside of the power button with the blister marked

As far as possible issues, the first would be the USB-C port assembly your charger was plugged into (left and right are the same dual port part) I assume you tried charging on the other sides ports, if you did that rules out a damaged port assembly unless it is shorted out. The next would be a deeper issue within the main logic board which would take a bit more skill and access to the schematics and board view drawings.

As far as accessing the files. There is a special port on the logic board which with the data recovery tool and a second Mac you can gain access to the files. You might find an independent repair shop which still has this tool, sadly Apple no longer supports this system and only the bigger store repair shops offered the service when you bought a new system (of course).

I would reach out to an independent shop to see if they can at least get the system going one more time to fetch the files off to an external drive.
