I’m not sure I could find my 2015(?) MacBook Pro in the fix guides as it’s 13” I think and has no ports except one USB-C. It still turns on but the keyboard won’t work and the battery is basically dead if unplugged so I can’t use it at all. I spilled water on it and the speakers died in 2016. I can’t find this MBP with no ports on Ifixit.
You can replace these but it would cost a !&&* of a lot of money: Keyboard (You’ll only have to get the cover/keyboard part if you have the screws and the power adapter if you don;t have one) Battery Speakers are individual so you may fix the keyboard and battery first and then see which one isn’t working. Left Right I would suggest getting the battery replaced, then by using an external keyboard find the speaker that isn’t working and then order the keyboard and faulty speaker together.
