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

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).

U1930 Removed. Still.

Its perfect - Internal and external.

That was the first thing i did.

Pretty Much Clean however, no AUDIO. 1- Audio codec recognized in the System 2 - Volume bar available 3 - No audio on the Headphones or speakers. Any hint?

Looks clean. However, i replaced and i got the same measurements: R1931 = 1 = 1.05V 2 = 0V C1930 = 1 = 3.3V U1930 = Pin 1 = 3.3V Pin 2 = 3.3V Pin 6 = 3.3V Pin 4 = 0V

Cpu_vccst_pwrgd = 0.34v

Plt_reset_l = 0v plt_rst_buf_l. = 0v
