A1534 No Power, But 14.5v At Fuse
Hey guys! So I recently picked up a a1534 for cheap. Previous owner said she spilled water on it a while back, let it dry out and it worked. After a few days the computer would only work plugged into a charger, so she attempted a battery replacement. She said after the attempted battery replacement, it wouldn't boot back on. So I opened it up and the first thing I noticed was bent pins on the type C connector to the logic board. I I unbent those assuming it would be smooth sailing from there, and that I probably fixed the problem. Wrong. I tested the fuse beside the DC in portion of the logic board and I'm measuring 14.5v and the LED beside the battery also lights up, however the machine is not powering on. Supposedly that fuse should be getting 20v, but I'm only getting 14.5? Anything I should check for specifically?
EDIT: I decided to pop off the CPU “heatsink” and the CPU gets warm! I'm so stumped on what to do.
EDIT#2: I downloaded board view + schematics and It seems like im getting no voltage on PP5V_S0 , could that explain my issue? 14.5ish + my missing 5V rail would get me to 20ish? Does that make any sense? I downloaded a board view software and i'm exploring around.
EDIT #3: I’m getting a similar problem here: https://www.youtube.com/watch?v=F-sTAO9B... . Depending when I measure, I’m able to catch fluctuating voltage, sometimes its a steady 5v, then drops to almost nothing. Unfortunately I have no way to inject current and find out where it’s shorting..
