I forgot to mention at the beginning. I've checked all the coils in diode mode and all seems fine.

LDO0: 0.8V Cycling LDO1: 3.0V Cycling LDO2: 1.2V Cycling LDO3: 1.8V ~ 1.78V LDO_RTC: 1.5V Stable VOUT_RTC: 3.3V ~ 2.69V LDO_CORE: 1.5V

Hi. Got this Mac to repair which has no signs of liquid. No previous history. Battery is dead, but I tested with a good working battery and still same. PPBUS_G3 - 12.7V PP3V3_G3H_RTC - 3.38V PP1V8_SLPS2R - 1.8V Cycling. T2 is glowing from one side and cycling. SLPS2 and Awake is all cycling...

U3200 replaced and fixed the problem Battery is now charging and working fine. Thanks for your help.

I replaced both and it now has C7020 - 3.5ohms C7023 - 3.1ohms It hasn't change the charging issue.

My bad, I was checking the resistance to ground. Over then is 4.5ohms on both.

Same voltages on the LDOs on all CD3215 chips, when no voltage on R7020. resistance (ohm scale) over C7020 - 50Kohms C7023 - 50Kohms

Same behaviour on all ports. Both sides. R7020 just get voltage without battery and charger stuck on 5V.

After disconnecting the battery and connecting it for the first time. The charger stays on 5v. P_IN - 5.15V AUX_DET - 1.28V SMC_RST_IN - 0V VDDA/P - 5.11V A/BMON - 0V Leaving the battery in and unplug and plug the charger then it goes to 20 and the voltages are: P_IN - 0V AUX_DET - 0V...

On battery. P_IN - 0V AUX_DET - 0V SMC_RST_IN - 0V VDDA/P - 5.11V A/BMON - 0V

PPDCIN_G3H is missing when the charger switches to 20V. Q7030 all ok, but none of the pins has power.

On R7062 - CHGR_CSO_R_N and R7061 - CHGR_CSO_R_P it should be 0.467 in diode mode, but instead it's measuring 0.372. Is this an issue?

U7000 replaced and still same. UB090 and U2890 replaced from a donor board and still same. I couldn't find the ROM files to flash into the ICs.

The Mac battery is dead. But the other one I'm using holds charge. It turns on with a charged battery, but does not charge. The first time I connect the battery and charger it stays on 5V. Then I disconnect the charger and plug it again then it goes to 20V and stays there.

With working battery it goes to 20V 0.02A. PP2V7_NAND_SSD0 - 0V PP0V9_SSD0 - 0V PP1V8_SSD0 - 0V PP3V3_G3S - 0V PP5V_G3S - 0V PP5V_G3S - 0V PMU_ONOFF_L - 3.38V PP20V_USBC_XB_VBUS - 20V PP3V3_UPC_XB_LDO - 3.3V PP1V8_UPC_XB_LDOA - 1.8V PP1V8_UPC_XB_LDOD -1.8V PP1V1_UPC_XB_LDO_BMC - 1.11V...

PP20V_USBC_XB_VBUS - 5V PP3V3_UPC_XB_LDO - 3V PP1V8_UPC_XB_LDOA - 1.8V PP1V8_UPC_XB_LDOD -1.8V PP1V1_UPC_XB_LDO_BMC - 1.11V

This LB has no signs of life. Stuck on 5V 0.294a on all ports. No liquid, very clean inside. Tried DFU and it gets stuck half way on installing system. SLPS2R and AWAKE voltages are present. No short on the board and all coils measurements is good. S5 voltages are missing. PPBUS_G3H - 12.28V On...

Ok. Thanks.

Sure! Here's your corrected text with improved grammar and clarity: Hi, I have an issue with this MacBook Pro 15" (Late 2013). It has kernel panics and everything points to a GPU issue. Using GMUX software, I can disable the GPU, and it works fine. I’m not sure how long it will last, but it...

No, it reacts SMC reset. But not the caps lock. Also no External display.
