Plt_rst_l = 3.3v

I pulled the U1930 and keep the R1931 nothing happen. J1800 area is clean. The board is pretty much super clean, actually. No make much sense to me right now....

When i pulled the R1931 I got back all the missing rails, however, i dont have CPU_VCCST_PWRGD. When i put back the R1931 the board going back to NO pp5v_s4rs3. I do have PP1V05_S0 Present (without R1931). I replaced U1930 already. I thought that was the issue.

PM_SLP_S5_L = 0V no Pulsing PM_RSMRST_L = 3.2V PPVRTC_G3H = 3.3V RTC_RESET_L = 3.3V PCH_SRTCRST_L = 3.3V PCH_INTRUDER_L = 3.0V

Pm_pch_pwrok = 3.2v pm_pch_sys_pwrok = 3.2 pm_sysrst_l = 3.2v

The board is pretty much clean, however, won't turn on. Here is some measurements: Without LIO FLEX: PM_BATLOW_L = 3.3V PM_PWRBTN_L = 3.4V PCH_DSWVRMEN = 3.22V PM_DSW_PWRGD =3.31V SMC_ONOFF_L Trigged: PM_PWRBTN_L = 3.4V Dropped! PM_SLP_S3_L = 0V no Pulsing PM_SLP_S4_L = 0V no Pulsing BYPASS...

cpu_vccst_pwrgd_r = 0.99v pm_sysrst_l = 3.3v pm_pgood_cpuvcc = 3.3v

PPVCCCPU_S0G = 0.7V and goes 1.5V after 10Sec and Comeback to 0.7V PLT_RST_L = 0.65V

I Tried with a flash drive (OSX) and doesn't work (no flashing).

Yes, i have USB/MOUSE activity.

Yes, the OSX Recognized the headphone. Everything looks fine. But no audio at all.

The Board is Pretty Much Clean. No external video as well. Here is some measurements: With Screen: PP3V3_S0SW_LCD = 0V PP3V3_S0SW_LCD = 0V DP_INT_HPD = 0V Without the screen: BUF_EDP_PANEL_PWR_EN = 0V PPVOUT_S0_LCDBKLT = 0V BKLT_SD = 12.85V PP5V_S0_BKLT_A = 5V PP5V_S0_BKLT_A = 5V PP3V3_G3H...

U1930 Removed. Still.

Its perfect - Internal and external.

CPU_VCCST_PWRGD = DM = 0.724 J1800 Clean R18000 Removed U1930 Replaced (twice)
