Me I'd be fixing the SSD board by installing the iBoff SSD modkit and a standard M2 2230/2242 SSD.

CPU transplant is doable without a BGA reworks station but difficult without some practice, DOSDUDE1 has done a few on the older machines with a pre-heater and hot air. Check out this video on an older 2015 Macbook Air.

Macbook A1706 touchpad and keyboard not working. Please help

by B2L_Repairs

Hi guys i am new to macbook repairs (i mostly do microsoldering on iphones and android devices. I need your assistance with macbook a1706 (touchbar edition) that came in without touchpad and keyboard functionality. External keyboard and mouse does work but the keyboard and touchpad on the macbook does not work. I changed the touchpad flex, also replaced the touchpad but the issue persisted. I then measured voltage on the board and found that PIN 44-50 of the touchpad connector (J4501) got 11.2V instead of 12.6V. Those pins required 12.6v and they get their 12.6v from PPVIN_S4-TPAD_FUSE . I measure...

A1706 - Macbook pro - one USB-C port only 20V 0A

by obelix24

I just got in my hands one Macbook pro A1706. It was originally not turning on (only 5V 0,2a on all ports (and 3 ports were restarting ampmeter when connected)

I've replaced one CD3215C00 IC and now macbook is fully working (20V and charging fine)

There is only 1 issue that one USB-C port is taking 20V but 0A (after replacing CD3215 it was fully working and i was charging macbook on this port) but then it just turns off (ampmeter) and started with only 20V 0A.

There were some broken pads under CD3215 but i've recreated them.

What should be...

Macbook Pro A1706 820-00923 no power after replacing top cover and keyboard

by johnbeton

Hello,

I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
This is what I measure so far:

Resistance from F7000 to ground is 123 Ohm on pin 1 and 2

PPBUS_G3H = 0,79v
PPBUS_HS_CPU = 0,79v
PPBUS_HS_OTH5V = 0,79v
PPBUS_HS_OTH3V3...
