This is the first board I have encountered that has bad PM_SLP_S4_L but still has good PM_SLP_S3_L and PM_SLP_S0_L. Not sure what to make of it. No S3 rails are up and most S0 rails are down except PP3V3_S0 is good. Liquid damage. Mostly around SMC. Already lifted SMC. Nothing under the...

Liquid got spilled into the hinge and now it has no back light. Already confirmed that it's a screen problem, main board is fine. I was hoping to find some corrosion on the the little display controller board, but it looks clean. Connectors look good. The two little back light cables look...

This board looks very clean except for one tiny dot of liquid on top of SMC. Nothing around it or anywhere else on the board. PPBUS_G3H is only 12.29v PP3v42_G3H = 3.4v SMC_RST_L= 3.4v SMC_BC_ACOK = 3.37v SMC_BC_ACOK_VCC = 3.38v SYS_ONEWIRE = 3.38v ADAPTER_SENSE = 3.4v It looks like green...

Dead. No LED and no fan. No obvious liquid. SMC area looks good. U5110 looks good. U7100 area looks good. PPBUS_G3H is only 8.18v SMC_RESET_L is always 1.15v If I jump R5100 with tweezers the fan starts and green light comes on. Measuring R5100 I am only getting 80k instead of 100k. But...

Sorry, I don't know where the board number is on this one... Complaint was USB port problems and high fan speed. I have yet to hear the fans spin fast though. Water damaged. Someone has attempted to clean the board so corrosion is hard to find, but it's obvious water did hit near one of the...

First time working on a USB-C board... Liquid hit U8210 and U3200. No visible corrosion, just sticky mess. The rest of the board looks flawless. Cleaned up U8210 and verified PP3v3_S4 and PP5v_S0 are being output. Flowed flux at low temp and ultrasonic cleaned to attempt to remove anything...

820-2850 with no visible water damage. Has visible prior repair near camera connector. Drop damage maybe. Has green light, charges, turns on and fans spin. Screen never turns on and no chime. Nothing on external monitor. No beep with RAM out. These voltages are out of spec...

I have a 829-3476 that came in mostly dead. Charger light would turn green then orange, but would never turn on. Checked voltages and found all of them present except for CPU_VCORE. Examined board and found a tiny bit or corrosion around U7600 and U8330. Cleaned it off then ultrasonic bath...
