from the looks of the tear down videos. most of these models look fairly straight forward. if you do decide to tackle this. a few tips take your time. if something isnt coming apart, theres usually a reason. maybe you missed a screw or theres a tab to lift \ remove. if you find yourself getting frustrated. take a short break. get something to snack on and come back to it. i cant tell you how many times this will save you a broken component. document your disassembly. take pictures. or take a sheet of paper and place the screws on the paper where you removed them. it is pretty defeating when you get it back together only to find a screw or part laying on your desk lol. be careful where youre poking around when you remove the heatsink. ive tried prying up on one near the CPU and popped a capacitor off. thankfully it wasnt a cap that was needed to run and didnt have to, but did resolder it back in place. i guess this kinda goes back to taking your time :) any questions post up!

might wanna check and make sure there isnt anything in there like double sided tape or something to wedge the battery so it doesnt rattle around. can you shake it and make the noise at all? that might help you narrow it down.

great picture. this is a pretty nifty site. hopefully itll help you https://www.retrosix.wiki/board-scans-game-gear

if its an original Xbox it probably needs to be cleaned out! from the sounds of it appears to be over heating some where. get some compressed air and see if you can clean the dust and debris out. if youre feeling super adventurous you can open that thing up and do a deep cleaning heres a YT video for you to follow! https://www.youtube.com/watch?v=mpw4bwin-n8 if that doesnt work for you. come back and update the question so we can continue to help you!

if you do a google search or 2 you might find a yt video on this. i personally wouldnt recommend doing this unless you know what youre doing. and thats part of the reason i wont link the documentation lol good luck!

2-3 months its probably under warranty. send it back to the manufacture for replacement.

what is not working? typically Airpods arent repairable unfortunately. this is because they glue everything together and if you open these it would be beyond difficult to get them back together.

honestly, this might be the wrong place to ask for something like that in regards to the 3d print stuff. i use https://www.thingiverse.com/ for any 3d printed stuff! heres an article about the PCB https://www.wellpcb.com/ps4-controller-pcb.html#:~:text=In%20a%20PS4%20controll.... good luck

typically youd need to take the vehicle to a repair shop that has the equipment to align them properly
