after liquid damage, MBA starts up and then shuts down login attempt
So, I spilled a liquid on my late 2010 MacBook Air. Between the liquid and the age, i know its got no warranty. As soon as i spilled it, i shut down and let it dry out (big ziploc and rice) until i could get the pentalobe screwdriver to open it up.
before opening it up, i wanted to see if the non-invasive drying worked. it starts up, but not by pressing the power button. when i pressed that, i got no response. so i just touched all the keys just to test the keyboard and it randomly powered on.
when i got to the login screen, i picked the account and was able to enter 3 letters of my password, then it stops and a few seconds later, shuts down.
any ideas what part needs to be cleaned/replaced? the magsafe port seems ok, it goes bright green and then amber to indicate its charging. SSD seems fine since it boots and appeared relatively unscathed. my guess would be logic board, but for obvious cost reasons, i am hoping there are simpler/cheaper fixes i can attempt first
