I get the amber light, I tried to start the machine with charger and battery but no changes.

@2informaticos yes R1410 has the correct value, compared to a known working board

@2informaticos, 3V3_S5/SUS is steady, R1410 has 3.3V on pin 1 but less than 1V on pin 2, when I disconnect the resistor from the PM_BATLOW_L line , i got 3.3V and there's no short to ground

@Gurmon am using an 85watts charger

Good day guys am currently busy on a board, and I am struggling to get the PM_BATLOW_L signal, I have replaced the known good SMC but no changes, the same SMC works okay on a different board and I get PM_BATLOW_L, but on this board, I don't have it, other SMC output signals are present and my...

@Gurmon thank you

@Gurmon, what else can I do?

thank you for your time, on the current machine I have at hand for the T2 error, what else can I do?

Am sorry, but am lost, so does this mean my CD3215s are working? I only have to worry about either the T2 or SSD? SOMETHING ELSE PLEASE: please do help me correct my understanding of fan issues, ((( when I start up the machine and the fan immediately becomes loud I attribute this to a fan...

I HAVE BUT NO CHANGES

PP3V3/5V_S0SW_LCD voltages are present DP_INT_HPD =3.3V And I am unable to spot any presence of image

Also forgot to mention that am using a fully functional screen, works on a different board. L8420 stays at 0.032V DIODE MODE WITHOUT SCREEN 1.272 DIODE MODE WITH SCREEN 1.270

BKLT_EN_R IS 0V

Good day guys, have got this board that displays fine on an external display but a black screen on its the internal screen. unit is not liquid damaged, below are some of the screen connector measurements EDP_PANEL_PWR_BUF_EN =3.2V DP_INT_HPD= 3.2V I2C_TCON_SDA_CONN=3.2V PP3V3_S0SW_LCD= 3V...

good day, guys, have got an 820-00840 that works okay, but when it goes to sleep, the machine would not display unless the battery is disconnected and reconnected, though the trackpad would be active during this time. even when I attempt to forcefully shut the machine down, it does not respond...

SSD_CLKREQ_L is 0V and the traces C3710-17 caps are good

I checked, with a known good SSD, also used its SSD on a different machine, I also cleaned out the connector, booted with a USB macOS , but the drive Is still not detected

Good day guys. please I need your help, have got 820-3476 that does not detect the SSD, at first would detect the SSD, but the machine would freeze once its booted to the desktop, then it eventually stopped detecting the SSD completed, below are the measurements I have of the SSD connector...
