yes i do have the official power adaptor after some inspection i do notice the cd3215 ic on the left side board [B](UB400 & U3100) [/B]have missing [B]PP1V1_UPC_XB_LDO_BMC [/B]on the current active port, and the usb tester keep boot looping on that side.yes i do have the official power adaptor after some inspection i do notice the cd3215 ic on the left side board [B](UB400 & U3100) [/B]have missing [B]PP1V1_UPC_XB_LDO_BMC [/B]on the current active port, and the usb tester keep boot looping on that side.yes i do have the official power adaptor after some inspection i do notice the cd3215 -
Thank you for replying one again
yes the voltage on [B]ppbus_g3h[/B] is stable at 3v42
check the voltage on the fuse [B]F7000 [/B]pin 2 0v29 and pin 1 0v042
after that i checked the resistance on each side of [B]F7000[/B] pin 2 have 5.86K and its not stable it keep jumping up sometime it reach 1.000K . Pin 1 have 0.642 milihohm and it have same condition like pin number 2 (not stable)Thank you for replying one again

Thank you for replying this are the following results I got after analyzing the voltage
[B]SMBUS_SMC_5_G3_SDA 3v27 not stable sometime jump to 3v41 and 2v66[/B]
[B]SMBUS_SMC_5_G3_SCL 3v29 not stable jump to 3v41 and drop to 2v79[/B]
[B]PPBUS_G3H F7000 both side 0v54 on pin 1 and 2[/B]
[B]PPVIN_G3H_P3V3G3H 4v8 sometime jump to 4v9 and drop to 3v8[/B]
[B]PP3V3_G3H both pin 1 and 2 have 3v42 [/B]

Macbook Pro A1706 820-00923-05 Stuck At 5V 0.03A
hello everyone, let me ask, I have a macbook which is stuck at 5v and 0.03 A when tested with a usb tester. Previously I wanted to replace the screen on the device, but by accident I forgot to unplug the battery. This caused the MacBook to get stuck at 5v, previously I had replaced the CD3215 (U3100) IC because it was warm. After I replaced it the problem was still not resolved. Please guide. Thank you -

thank you for replying mon2 when i plug the charger to mac i only got 5v11 and 0.29A with the first usb c port, if i use the second one the usb tester doest show and boot as it should....Leave a comment:

hello mon2 i got some news, when i trying to inject voltage on pin #2 [B]R6999 [/B]i saw that [B]U3100[/B] heating up and before i test to inject the voltage there are one usb port that does work on that ways. If i change the ic i will get change to repair this mac?

im sorry but are this the correct way to check the resistance on pin #2 [B]R6999[/B] i put the black prob on the ground and red one on the pcb pad #2. After that i set my multimeter on 200 ohm? I'm sorry because I'm not someone who really understands electronics, I'm just learning to understand it. and sorry, I only use Google Translate as a communication medium so the language is not very good. Thank You

First off all thank you for replying, i. have tested [B]SMBUS_SMC_5_G3_SCL[/B], and [B]SMBUS_SMC_5_G3_SDA[/B] both side are 0v with the r6999 still removed
on [B]R6999 PP3V3_G3H_REG_R[/B] pin #1 3,46V and [B]PP3V3_G3H[/B] pin #2 show. 0v
Measure resistance to ground of [B]PP3V3_G3H[/B] using diode mode i got 350 ohm with the red prob on ground and black prob on [B]PP3V3_G3H[/B]
Measure diode [B]D6905 [/B]pin #1 ([B]PPBUS_G3H_R) [/B]i get 464 ohm, on pin #2 ([B]PPDCIN_G3H_CHGR_R[/B]) 595 ohm, and on the pin #3 ([B]PPVIN_G3H_P3V3G3H[/B]) i get 590 ohm
Measure voltage...Leave a comment:

hello mon2 sorry for distrub your time may i ask you? i have same problem with my macbook pro a1706 which is have lower pp3v3 it only showing 2V. I have been trying to. remove R6999 which is susccesfull i got around 3v more on the L6995 pin #2. The mac only takes 5.13V and 0.30A while charging. notes: sorry with my bad english spealing im not really familier with english. Thank you for the help...Leave a comment:
