Hi all, working on a MacBook Air A2179 EMC 3302 stuck on Apple Logo. Came in dead. There was spillage on both of the USB-C Charge port connector. I replaced the cap 4.7UF 25V near the speaker connector as it was corroded. Replaced USB-C connector with a new one & now I get display. The problem is that gets stuck on the Apple logo & sometimes it even boots up into OS after a very long time & the CPU fan spins fast. Kindly any repair tips will be appreciated. Do these logic board have BIOS, so that I could do a clean up or load a new dump. Thanks in advance.

Re: MacBook Air A2179 stuck on Apple Logo
Just to update all... These models DO NOT work well if a known good battery is not installed. In my case the battery was dead & all eratic behaviours. Sometimes it was booting up & sometimes just stuck at the Apple Logo, fan spin was in full blast. As soon as I replaced with a Good New Battery, all worked fine, no errors.
