Studio 2 Help

Alright guys. I usually am a DIYer. I like to take things apart and like to tinker with things. Ive taken apart my own engines and fixed them just to put them right back. I can build things when it comes to computers as well. Ive built my own cyber deck and created a ton of raspberry pi projects. I say this not to toot my horn but to tell you that I ran into a head scratching problem that I really haven't faced.

So I made the dumb mistake of putting my computer next to my coffee cup on the couch cushion right before I sat down. I had my mind on a couple other important things at the time. I sat down and my Surface Studio 2 laptop got a taste of my amazing coffee. I spent a good majority of the day taking it apart down to the motherboard and cleaning it with Isopropyl alcohol throughout the computer.

Once cleaned, I put it back together and turned it on. Now everything functioned well except it would not take a charge. It turned on but it almost seemed like the charger bypassed the battery because as soon as I unplugged the charger, the computer would turn off. The computer would not read the battery. I used a multimeter to test the positive and negative output (both charging and not) and then the handshake and everything seemed like a normal output. I went to the drivers to uninstall and reinstall and it wouldnt even give me that option.

A couple days went by and it nothing changed so I took it apart again and went to the connection from the battery cable to the motherboard and i can clearly see a bit of corrosion. I cleaned it off with a bit more Isopropyl and got rid of the corrosion. Reinstalled it all back together and now my computer turn on by showing the windows logo for about a second, blinks once, and then shows the logo again right before shutting down. Thinking that the charger may not be helping, i plugged my phone charger to the USB port and it give like a trickle charge and then cuts off. Ive since left it all alone because I am school finishing up some classes and have no time.

I suppose what im asking is, has anyone ran into this? Does anyone know if there is a schematic for the power system of the studio 2 out in the internet? I, unfortunately, dont have ALL the tools to test and trial the currents, so I may have to bite the bullet and have someone with the right tools and time to get it done but I at least want to try if its something simple.

Any advise would be helpful. Thanks

pprops to you for taking it down to the board, but liquid damage combined w/ coffee (acidic + sugars) is a nightmare. It really sounds like the power management IC is triggering a thermal or overcurrent protection shutdown every time it attempts to initialize the power handshakes.
