any idea why PM_SLP_S3_L 1.753V

noticed PM_SLP_S3_L light pulse 1.753V to 1.816V No pulse at all at PM_SLP_S5/4_L :/ ALL_SYS_PWRGD : 0.014V

PM_BATLOW_L : 3.304V PM_RSMRST_L : 3.277V PM_PWRBTN_L : 3.386V PCH_DSWVRMEN : 3.209V PM_DSW_PWRGD : 3.390V When trigger SMC_ONOFF_L, voltage drop to 0.346V while 3sec and up to 3.386V PM_SLP_S3_L : 1.753V PM_SLP_S3_R_L : 0.023V PM_SLP_S4_L : 0.000V PM_SLP_S5_L : 0.000V PM_SLP_SUS_L ...

History little liquid damage U7840 area and U5110 orange light present tried good audio board, cable, magsafe know SMC_ONOFF_L 3.391V PP3V3_S4 0.080V PP3V3_S0 3.305V PP3V3_S3 0.023V PP5V_S5 5V PPVRTC_G3H 3.304V PPBUS_G3H 8.53V PP3V42_G3H 3.395V SMC_ADAPTER_EN 3.39V SMC_RESET_L 3.363V...

PM_PWRBTN_L drop 3.402V to 0.300V no pulse when SMC_ONOFF_L pressed

PM_PWRBTN_L : 3.406V SMC_ONOFF_L : 3.415V no pulse stable How use Bypass mode ? short R5115 or plug keyboard on power button many seconds while plugging charger ? (if i remember)

thank you for information RTC_RESET_L : 3.290V PCH_SRTCRST_L : 3.290V PCH_INTVRMEN : 3.201V PCH_INTRUDER_L : 3.017V

PM_RSMRST_L : 3.265V sorry for check signals i don't have oscilloscope, page 12 i've PCH Decoupling

for rtc signals i check all point of PPVRTC_G3H i've got 3.298V Original and correct charger sure U8130 voltages : 1: 3.295V 2 : 3.295V 3 : 0.243V 4 : 3.269V 5 : 0V 6 : 3.265V

checked all RTC signals : 3.298V PM_BATLOW_L : 0.035V S5_PWRGD : 3.387V PM_DSW_PWRGD : 3.415V PCH_DSWVRMEN : 3.201V SMC_ADAPTER_EN : 1.048V PM_RSMRST_L : 0V

History no liquid damage, just stopped working pins of U7100 : 17/18 : 3 Ohms 27/28 : 20.7 Ohms PPBUS_G3H : 8.534V PP3V3_S5 3.295V and PP3V3_SUS 3.294V SMC_RESET_L steady high 3.387V

Board no power on green light and orange light present but after few seconde return to green light and orange light again Tried good magsafe 45w, io board and cable good know PPBUS_G3H 8.53V PP3V42_G3H 3.42V PP3VRTC_G3H 3.29V ALL_SYS_PWRGD 0V replaced R7121, 7122 of U7100 because value too...

hello i need to know pin to shorted on ssd for bypass fan full speed after ssd upgrade please for this board

so SMC_ODD_DETECT 0.056V when odd plugged, if unplug odd i've 3.3v

exactly i will get new one odd for test ;)
