A1466 00165 missing pm_slp_s5_L

[donnos]

Unit came is as dead, no light on magsafe
Found smc shorted, and pp3v42_g3h 8.7V
replaced SMC, U7090,R7095,R7096. and now get orange light on charger.
Still does not boot.
RTC voltage and pch signal all good but missing pm_slp_sus_l. This needed for pm_slp_ s5_l signal? or dead CPU

Do you get 3V3_S5 now?
Post exact PPBUS_G3H and 3V42_G3H voltage.

 

[donnos]

PPBUS - 8.57
3v42 - 3.41
and yes i get 3v3_s5

 

[2informaticos]

Post SMC_ADAPTER_EN, PM_BATLOW_L, PCH_DSWVRMEN, PM_DSW_PWRGD.

 

[donnos]

SMC_ADAPTER_EN - 3.4
PM_BATLOW_L - 3.3
PCH_DSWVRMEN 2.6v - Diode mode 0.796
PM_DSW_PWRGD 3.4

All these look good.
Post now all PCH's RTC signals.

 

[donnos]

PCH_SRTCRST_L - 3.3
PCH_INTVRMEN - 1.8 / 3.3
PCH_INTRUDER_L. -1.8 / 3.3
SYSCLK_CLK32K_RTCX1 - 32KHz on o-scope

but i find the reading abit inconsistant in the sense sometimes i get low reading about 1.8V for INTVRMEN and INTRUDER but when reconnect magsafe it goes to 3.3.

Steady 3.3V at PPVRTC_G3H?
PCH_INTVRMEN and PCH_INTRUDER_L are influenced by voltmeter impedance; measured voltage can drop until 2.4V.
These signals cannot drop under 2.1V, or the machine will not work properly.

 

[donnos]

yes steady.
I used the o-scope and got consistent 3.3v from it. bye bye CPU

Did you check RTC_RESET_L too?
