2 keys on keyboard not working
I have a early 2020 MBP where the A key and the D key do not work. I checked under key cap and theres no debris. What are other steps I can do so i dont have to purchase a whole top case just for these 2 keys. the top case that in there now looks to be in prestine condition. Ive heard of different methods including heating with blow dryers and contact cleaner.
After buying a 300$ whole new topcase, the issue of A and D keys persists. Its now clear to me its the motherboard. What options do I have? I vaguely remember this units screen having water damadge and didnt think it had got to the board because it booted up and ran no issues. Ultrasonic cleaner is all I can think of
