ok now i have PPBUS_G3H=8.18 3V42_G3H=3.42 3V3_S5 3,3 no voltage for PP3V3_SUS (no shorts on u8020 i have 0v on P3V3SUS_EN no shorts 0v on R1464 no shorts

even changing u8100 no luck... :(

i don't know the history of this motherboard...i've found in diode mode a super low value on pp3v42_g3h...removing l7095 and l7090, i've injected voltage on the line and found that u5000 become hot (3v 0,0100 amp) should i reball it? should i change it?

so it was unusefull to buy another u8100? (50 Euro🥲)

What do you think

i've check on all 6 big coil...all ok except P3V8AON sw1/sw2/sw3 shouls be 0.350, i have 0.150 reflowed u8100...no luck so you think about u8100.....but why you give me a link about wifi chip ?

PPBUS_AON 12,2v stable and 3V8_AON 3,7 stable on u8100 PP1V2_S2 0v floating 1,2 PP3V3_S2_UPC floating 3v/2,5/1,6/0 PP1V8_AON_MPMU 1,7 MPMU_VREF_ADC is 0,020v on u7700 PP0V72_S2_VDD_LOW 0v PP1V2_AWAKE_PLL 0v PP1V8_AON_SPMU 1,7 stable PP0V855_S2SW_CIO 0v PP0V805_S1_VDD_FIXED 0v PP1V2_S2_CIO 0v

P3V3S2_EN fluctates...from 1,7 1,4, 0,8 0 in loop

soldering an 1.5UH-20%-12.5A-0.01OHM (just for test) in the place of lc710, i have 0,430 diode mode and higher resistence (i'm not able to read the value because it change continously...like from M to K) THIS IS REAL

why you say that? on PP3v3_S2.i've no short anymore...if i go with power supply on that line, nothing happen....so i think this line is fixed?! soldering an 1.5UH-20%-12.5A-0.01OHM (just for test) in the place of lc710, i have 0,430 diode mode and higher resistence (i'm not able to read the...

you mean comparing with opernboardata? now i have 0,200 / 0,600k resistence to ground openboard data says 0,400 /40m :( PP3V3_S2_WLBT_ISNS is 0,025 in diode mode,47 ohm resistence to ground

i dont understand: is this problem related to the fact that i have unstable ldo and macbook cant switch to 20v?

So it Could be a Wi-Fi problem? In This case, doing the “cut mod” i should use a Wi-Fi adapter right?

i can clearly see that above wifichip become hot removing rd810, short is gone...so now what?

Do you think it’s a short Line? how is it possible that i have floating voltages even if i have disconnected lc710 where the short is?

i've removed lc710 (to isolate the line but removing it i've broken it...) I have 47 ohm resistence and 0,023 in diode mode on pp3v3_s2 Line.. If i inject some voltage, the Line takes 0,050A but I can’t find anything under termal camera

PP3V3_S2_UPC3 3,3v floating PP1V25_S2 0v PP3V3_UPC0_LDO 3,3 PP1V8_S2 1,7 floating USBC0_3V3LDO_EN 1,7 floating UPC0_SS 0v PP1V5_UPC0_LDO_CORE 1,5v PPVBUS_USBC0 5v PPHV_INT0_AONSW 5v

on u7700 i have only one ldo output: PP1V8_AON_SPMU and it is 1,7v all others ldo are 0v

pin 17, 18, 5, 4, 24, 12. 12, 5, 5, 5 3,3 3,9 3,3 on l77100v on l7750

removing d3302 and d3322 i've not short anymore.... now how can i substitute those components?
