I think its a bios issue as pin 1 have 1.4 instead of 3.3volts, i have u6101 and u6100(with clean me) but it still gets 1.5v. when i remove u6100, it will have 3.3v

Yeah there was bit of a liquid on lcd connector

Yes i have 3.3 on pin 8, sorry my bad

i didn't replaced those chips Yes all port are working, one thing i noticed that on working board pin 5,6 of u6100 don't have any voltage and rest of pins have 3.3v, but on this one pin 5,6 have .9 and .7 v and rest of pins have 2.4v. can it be a bios issue?

Have minor liquid damage around cd3215 chip cleaned it and tried to turn it on but nothing happening, board does goes to s0 state as l7210 is outputting voltage, one thing i noticed that whenever i plug usb c charger in, mosfet near cd3215 gets extremely hot for a brief second and then it cools...

No voltage at pin 6 and 11 of u8600 and no cpu vcore, but there is gpu vcore present

Previous repair attempt, every rails is present till ppddrvtt_s0, checked u7300 and found that pm_en_ldo_ddrvtt_s0(enable for ppddrvtt_s0) is missing, and that is memvtt_en which is also missing, traced it further and found that memvtt_en will come if u2110 have pm_slp_s3_l and plt_reset_l...

Checked data lines on cpu side and all have .300v drop to ground

No voltage across l7410,20,30. I have checked working board aswell, it also doesn't have any voltage on those coils, i will check data lines and see what they say.

Its a water damaged board, damage was mostly around vcore coils and u6100, cleaned everything and board boots up but there is no image or backlight on screen, there is usb activity when i connect external device and cpu also gets warm. Vcore starts from .9 volts and then drops to .6 volts after...

i think ram is not bound to bios or cpu, recently i replaced 16 ram chips on 2011 11" air and its working fine, i took those replacement chips from 2gb ddr3 ram stick for laptops.

i also got one board that was crashing and spent many hours try to figure what was wrong with it, nothing worked, then as a last resort i retinned all qfn chips and it has been 2 months and its still working fine.

Thanks man.....

no, that's how i got it from dealer through gsx parts exchange, its a brand new board.

this is a new board and its showing that serial number is unavailable i have removed and read bios, there is a serial number showing there, this is my first time writing serial number to this board, so i am getting bit confused, can someone write it for me...

checked them and they are fine, even reballed the smc, but still same thing

Got hold of asd, it shows sensor pcpt, tc0c, tc1c are failed

had minor corrossion on few chips, now it turns on, but takes too long to boot, fans are spinning fast and its lagging. hwmonitor says: cpu core 2, 3 = 128c cpu proximity 35c peci sa 128c peci gpu 128c cpu core 1 128c whar sensors are responsible for core tempratures? i can't find asd for this...
