Hi everyone. Yesterday I tried to turn on my Mac, but it showed no signs of life. I opened it and saw this burned out element. Can anyone tell me how to fix it?

That is a tantalum polarized capacitor that has exploded. Very likely the part is shorted and causing a very low resistance to ground which is forcing that power rail to shut off.
The large black bags under this region are your batteries. For this reason you cannot hot air this capacitor for replacement. The battery pack can heat up and explode or cause a fire.
The board will need to be carefully removed and the part replaced. Would you have a local phone repair shop in your area? Mention the above details to ask for a quote. We can look up the capacitor value next. -

The tantalum capacitor that has exploded is C7600.
See below and share with the pending tech. Be sure to ask them if they are comfortable with low level soldering of SMD (surface mounted devices) parts. As noted, the battery pack should not be heated because it is a serious fire hazard and can cause injury or death.
Next, need to find a suitable replacement part. Will chime back later with details.
Here is a suitable replacement - tantalum (polymer type; 16v; 3528 footprint) - the package is slightly smaller than the B3 case style used by Apple but should be ok to solder into place on the board. Often when such capacitors fail, they simply short circuit across the pins so this power rail should have a very low resistance to ground. This action then forces the power rail to turn off. That is, by replacing this part, you should be ok to operate the unit again (crossing our fingers).

by tech_guruHello. If you could please help me understand what I am doing wrong...
This model, Macbook Pro 2019 16" A2141, 512GB, EMC 3347, with T2 Security Chip, had 4 NAND Chips shorted in 1 wing (U9100, U9200, U9300, U9400) and it has 1 more in the 2nd wing (U8600) BUT NOT shorted. All chips are TSB4227 TOSHIBA-KIOXIA SN4192TWNA12014 BGA110 128GB. I got 4 new nand chips for 1 wing and programmed them by specific position of course with JCID P13 programmer.
I also replaced the tps power ic for the ssd.
Now all rails come up, including the ssd rails 0.9v, 1.8v, 2.5v.... -

Ok, here's an issue ive got on a A2141 820-01700 MBP 16' 2019. No signs of life, 5.06v 0.0a on usb-c meter, on each 4 usb-c ports.
Nand voltages are missing.
I've found no shorts at all so far, no signs of heat via thermal camera either.
PPBUS_G3H 12.31
PP3V3_G3H_RTC 3.387v
PP3V3_G3H 12.31v
PP2v5_NAND_SSD0 0v 58 ohms
PP2v5_NAND_SSD1 0v 57.8 ohms
PP1v8_SLPS2R 1.8v
PP1v1_SLPS2R 1.1v
P3V3_G3H_SOCPMU 3.37v

by tomtom67A 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... -
by martyjelenHello, I have this Macbook A2141. It stuck at 5V / 0,075A. I measured all 4 ports, all the same. PPBUS_G3H is present but only 12,3V. Should be 12,6V ? according to this article : https://repair.wiki/w/MacBook_Pro_A2...w_at_5V_repair
PP3v3_G3H_RTC_X is present - 3,3V
PP3v3_G3H_SOCPMU is present - 3,3V
What else should I check?
Thank you for your help. -
by rathore4uHi all,
I am trying to fix a T2 Macbook A2141 820-01700 board that's stuck in DFU mode.
The SSDs have correct voltages
PP2V5_NAND_SSD0 = 2.5V
PP2V5_NAND_SSD1 = 2.5V
PP0V9_SSD0 and PP0V9_SSD 1 = 0.9V
PP1V8_SSD0 and PP1V8_SSD1 = 1.8V
I can force the laptop to DFU mode using the SOC_FORCE_DFU using SWK003. Apple Configurator 2 tries to restore the Mac but it fails back to RECOVERY.
Looking at the diagram here - https://repair.wiki/w/Apple_T2_platform Step 6, it says the problem could be loading from SSD,... - Loading...
