The board just stop work. F4700 = 5.2V F7140 (PPBUS_G3H) = 0.23V - DIODE MODE = 0.424 L7130 = DIODE MODE 0.415

R9606 its fine. Voltages: R9606 = 5.2V D6906 = Pin 1 = 0 - Pin 2 = 5.2V - Pin 3 = 3.9V C6990 = 3.9V

R7020 = 5.15V 3V3_G3H = 2.26v U6990 = 1 = 4.89V 2 = 3.29V 3 = 2.26V 4 = 0V 5 = 0V 6 = 0V 7 = 0V 8 = 3.9V 9 = 0.06V 10 = 5V L6990 = 0.331 (diode mode to ground with red probe at ground) F7000 = 0.075 (diode mode to ground with red probe at ground) L7030 with black probe at ground = 0.469

Diode mode to ground at F7000 AND L7030 F7000 = 0.083 L7030 = 0.364 PP3V3_G3H = 2.26V

Right now, for some reason im getting 5.15V on PPDCIN_G3H

No liquid damage. Getting 20V on the USB Power Meter. However, 0mAh. No short to Ground PPBUS_G3H = 0V U7000 C7075 = 5V C7077 = 5V R7073 = 3.3v L7030 = 0.2V BOTH SIDE Seems the U7000 is bad.

U8300 Pin 4 = 5V and others pins = 0 I replaced and works ! Thank you for the hint!

External works great! L8300 Without the screen, gave me 2.9V and drop to 2.1V and stays like that.

No drop history and no external video.

The board is pretty clean, no liquid damage at all. However, i don't have any video (even external). I have mouse light and chime. I feel pretty lost and I'm sure you guys can help me out. Thank you

PPBUS_G3H = 12.58V PPVCC_S0_CPU = 1.7V NO USB activity SMC is pretty clean. I think is the bios as well.

I have a hard time to figure out the problem with this motherboard. If you guys can give me some hints, i will really appreciate. Water Damager near by U1900 Replaced Pin 1 = 3.3V Pin 13 = 3.4v Pin 2 = 3.3v PPBUS_G3H = 12V PPVRTC_G3H = 3.3V PP5VS5 = 5.1V PP5VS0 = 5.1V ALL_SYS_PWRGD = 3.3V...

PPBUS_G3H = 8V Yes, i do green/orange light.

The board looks super clean, No liquid damage at all. Here what happened: PPBUS_G3H Was short to ground because of C7377 (PPBUS_S5_HS_COMPUTING_ISNS). I replaced and I got back PPBUS_G3H. However, I don't have PP5V_S0 even PP5V_S5/S3. SMC_PM_G2_EN = 3.2V PM_SLP_S4_L = 0V PP5V_S5 = 0V PPVRTC_G3H...

PM_SLP_SUS_L - Is present PM_BATLOW_L - No Present and Short to ground is 1.600MΩ RTC - I can't check Original Charge

I have green Light, PP5V_S5 but i dont get PP5V_SUS, PM_SLP_S3_L and PM_SLP_S4_L PPBUS - 12.62V PP3V3_S5 is Present PM_SUS_EN is Present SMC_ADAPTER_EN is Present

Short to ground on R5171 with Audio Cable: Pin 1 - SMC_LID = 115.3 k Ω Pin 2 - PP3V42_G3H - 054.6 k Ω without cable: Pin 1 = 187 k Ω pin 2 = 054.6 k Ω

Already have this measurement : R5171 is 99K on the schematics is 100K. I will check R to G when i back to the office.

Duke, I pulled the resistor. After i pulled the resistor, with ou without the cable audio i don;t get backlight

I don't have a good board for test, but i have measurement in both sides: pullup resistor: R5171 - Pin 1 - SMC_LID = 0V Pin 2 - PP3V42_G3H - 3.42V Diodo mode My board With Audio Cable and IO connected: Pin 1 - 0.405 - without Audio Cable - 0.600 pin 2 - 0.282 - without audio cable - 0.282
