Sure no pulse at PM_SLP_S4_L
RTC_RESET_L = 3 v
PCH_SRTCRST_L = 2.9 V
PCH_INTRUDER_L = 1.5 V
PPDCPRTC_PCH = 1.1 V
PM_DSW_PWRGD = 3.3 v
PPV0PCH_REG_R = 0.9 V
PP1V_PCH_REG_R=1.5 V
voltage on big coil L7030 Cant detected changed from 25 to 31 TBA phase 2
update
after trigger SMC_ONOFF_L and check for drop pulse at PM_PWRBTN_L at same time.(from 3.3volt to 0.3 volt)
PM_RSMRST_L remains high all the time. (3.3 volt)
nothing change on the usb meter ( 20.1 volt - 0.06 A)
i dont understand what do u mean by trigger SMC_ONOFF_L and check for drop pulse at PM_PWRBTN_L at same time.
smc_onoff_l is high 3.3 volt
PM_RSMRST_L high all the time

smc_onoff_l is high 3.3 volt
PM_RSMRST_L high all the time
the Amp meter shows 20v- 0.06A
Resistance To Ground for the big coils:
L7030 = 292
L8410 = 1074
L7660 = 341
L7600 =409
L3500 = 150
PPDCIN_G3H_CHGR = 20 V
PPVBAT_G3H_REG = 13 V
PPBUS_G3H = 13 V
PP5V_S4 = 0 Volt
PP3V3_S5 = 3.3 Volt
P3V3G3h = 4.9 V !!!!
3V0_G3H = 3 V
the macbook start normal untel i put the password stay 1 min and restart with black screen
if i turn it off and start it again the mac work normaly and after 1 min repeat the problem.
i change the pasta under the heatsink but nothing change.
i dont know from where can i start to measure in this...
direct also 52 volt
my question about the j8300 connector
i use one from a1466 -is it the same connector?
what about important signal to the screen need to measure also?
