3.3 volts at pins 18/19 of J8300 for a few seconds when machine chimes, yes. Connector looks good, continuity on all pins. l2c sda/scl lines check out too. DP_INT_HPD 0 volts

We have an 820-00165 that customer said was flickering all of a sudden and then it just went black. He said he didn?t drop, didn?t spill anything on it. No faint display when flashing a light over it. No signs of corrosion - completely clean. Tested a known working board and the display assembly...

Good news.. I came back to this and the CD3215's seem to be working better. Since I removed that resistor in place of NO STUFF C3120, I replaced the CD3215 chips and I now get 5V.. 20V steady on both ports. I am able to disconnect and reconnect and they do not blow. However, each port is drawing...

Removed re-driver, same behaviour. I found out last shop put a resistor in place of NO STUFF C3120 (for primary) which I removed. Also seen that R5322 (SMC_USBC_INT_L) not properly soldered on. Soldered new CD3215's, diode mode shows no obvious shorts. Plugged into secondary port, 5V.. 20V 0.08...

Volts on PPBUS and S0 rails?

Yes, I meant to say SMC from same model donor board. Not technically new. Tried reflowing CD3215?s many times as well as replacing. I?m 99% certain good solder. The USB-C redriver chip that isn?t on board view / schematic near the connectors is clean with no burn marks. I don?t have any...

Hello, I have a complicated 820-00840 that came from another shop. Many parts have been screwed with including CD3215C00 area, F7000 (only one side connected), C3000 was missing. Replaced secondary CD3215C00 because it was very hot. Still 5v on type C charger. SMC was shorting PP3V3_G3H...

I am not too sure what happened, but the ISL U7000 got reflowed and it started working. Didn't see any signs of corrosion here, but it did the job. Unfortunately, I don't have too many reliable suppliers for batteries... mostly Amazon. :/

Battery screwed tightly 100%. Without the charger connected, old battery shows 2v (most likely because it's dead and hasn't been charging) and new battery shows 11.5v. PP3V3_G3H is present with battery only only if new battery is put in. Old battery is probably just dead. How do AMON/BMON...

Hello guys, I have a 820-00239 running perfectly fine except that it doesn't want to charge the battery or run off the battery. Battery is detected and charging symbol shows. PPBUS_G3H = 13.1v Q7065 pins 1,2,3 (PPVBAT_G3H_CHR_R) = 13.1v pin 4 (BGATE) = 13.1v pins 5,6,7,8 = 11.6v When MacBook...

I was able to fix the issue by replacing R6110 (SPI ROM data line) 22 ohm and R1452 (PCIE_WAKE_L) 10K ohm Thank you for your help!

Very ugly. I used an external hard drive with link LED (macOS Installer) and it shows no USB activity. Normally the light will stay on and fade in and out as it reads/writes data, but this one will flick on and then forever off quickly. LCD connector looks clean - no corrosion or signs of...

Hello guys, I have a laptop that does not boot and it only tries to turn on when the battery is disconnected. Corrosion on PP5V_S0_KBD on the keyboard/fan connector. Cleaned up and fixed some of the pins. One of the redundant PP5V_S0_KBD pins are burned and not connected, will fix later...

2informaticos, just seen your post now. I just want to update that replacing the SMC did the job. Computer recognizes battery and it is charging.

Looks like the SMC was replaced or reballed before. There is little to no space in-between the chip and the board and the edge bonding is gone. I'll give it a try thank you.

It does not recognize the battery in OS. Every time I try to check the box to enable battery percentage, it unchecks itself.

Hello, I have a board that turns on, but does not charge and will only run off the adaptor. I switched it with a known good battery and it still will not charge, but it can run off the battery only if I first turn it on with the adaptor connected. Green light on charger and never turns orange...

Thanks. I ultra-sonically cleaned it and when I first plugged in the adaptor, green/red light and no fan spin. Replugged it in and no more light. Sometimes if I leave the adaptor in it would go green/red after like 20-30 seconds which is odd. What could be the cause of this? I will test the...

CPU Vcore would go to 1.7 volts and then to 0. I'd like to clarify that the voltages are measured for a split second and would go to and stay at 0 until I replug the power adaptor.

Hello guys, I have here a troubled 820-3437 board. When plugging in the original adaptor, the fan would do a quarter spin. All G3H rails are good. It would go to S0 state for a split second and then drops. U8080: - PP5V_S4RS3 would go to 5V and then goes to 0 - P5VS0_EN would also go to 5V and...
