This was liquid damaged and been to another shop. as its been cleaned its hard to tell whats been damaged but looks like area around smc, bios and u7090.

820-3437. Was liquid damaged around u7200. pin 30 testpoint was corroded out. i replaced the chip and ran a wire to r7280. i now get fan spin for 15 seconds turns off then back on full speed. no led flashing on pen drive.
00165 it boots up and gets stuck on full progress bar.
tried with known good ssd and fresh os. os installs fine, but will not boot.
randomly will boot all the way but will be really slow inside 10.15.
no damage to the laptop nor any liquid.

board is stuck on 5v
diode readings on
ppv3v3r3vo_AON - .02 (beeps)
