Macbook a2141 5V 0AMP

11-20-2024, 03:57 AM

Hi,

I'm currently working on the a2141 motherboard, 5V 0amp.

PPBUS_G3H - 0.380
PP3v3_G3H_RTC_X - 0.420
PP3v3_G3H_SOCPMU 0.360
PP2v5_NAND_SSD0 on L9581 - 0.010
PP2v5_NAND_SSD1 on L9081 - 0.424
in diode mode

CHGR_VDDP 1.8V
PPDCIN_G3H - 5V
R7021 — 1.00 Ω
R7022 — 1.00 Ω
R7061 — 1.00 Ω
R7062 — 1.00 Ω
Dfu does not get device detected

Each CD3217 have same reading

I was thinking about replacing ISL as it does not create 3/5v however NAND_SSD0 seems extremely low. Any advice?

Macbook Pro 16" A2141 screen artefacts, kernel panic

by sofles

Hi there.

I have Macbook Pro 16" 2019, model number A2141, motherboard number 820-01700. I have some problem with dedicated graphic card. When Macbook switches to dedicated GPU it is getting instantly hot and starts to show glitches on screen, then it freezes (trackpad is not clicking anymore) and shuts down.
I tried to reinstall MacOS But it was a pain, it started to show glitches in middle of installation and I could not finish it. I only was able to reinstall MacOS when I put Macbook outside (it is winter and -2 Celcius).

Now situation looks like this, If...

MacBook Pro 16" (2019) A2141: power consumption? Dead GPU? MacOS not installing

by tomtom67

A friend brought his fresh-from-ebay macbook pro A2141 after he failed replacement keyboard plugging.
I fixed all the little problems he introduced.

I am unable to install macOS to this device. Both Sequoia and Catalina (from Internet Recovery) start to install, but after ~2-5 minutes into the installation the macbook does a hard restart (max fan spin for a split second, then reboot without chime).

I noticed what I think is a very high power consumption, like 20V/1.7A when activating WiFi for internet recovery, and more like 20V/3.7-4.1A while downloading the recovery...
