With other fan is also at full speed. FAN_RT_PWM = 4.58V FAN_RT_TACH = 1.66V SMC_FAN_0_TACH = 1.65V SMC_FAN_0_CTL = 3.28V PP3V3_S0_FAN = 3.32V Resistor values are good.

I tried all sensors, and fan is always at full speed. Is there another way to limit fan speed?

Hi again, after the change of U5800, the CPU 1, CPU 2 and Memory Proximity show normal value. Fan are still at full speed. Also PECI SA at moments show 0°, but most of the time shows some value, even showing a value fan at full speed. Trying to lower the speed with fan control, does nothing...

I test board in another case, with known good LIO flex/board and trackpad flex/board. Same problem. R5360 and R5361 are good, 2k resistance each. I also test a known good board with the LIO flex/board and trackpad flex/board of the water damaged board and all works fine, fan at normal speed...

Hi, I receive a water damage board. After cleaning the board and changing the trackpad flex. Fan spins at full speed. I install hwmonitor and CPU 1, CPU 2 and memory proximity shows 129°. U5800 area looks fine, no water near it. Traces to Q5810 and Q5860 have continuity. With webcam unplug...

Hi, today I receive this machine, fan speed is high always, it takes 3 or 4 bottom press to power up, it doesn't power up just connecting charger. I install hwsensors and only shows SSD T°, also battery info is not available. Battery don't charge, and when battery is plug, charger light turn...

Hi, Board is water damage, most corrosion was in the little caps around the XA/XB USB port connector. Also C3101 was looking nasty, I replace the caps, no shorts detected, just ugly caps. When I plug the original charger with an amp meter I get steady 5.11V in XA port. XB port pulses 5 seconds...

Hi, Board is not water damage, inspecting board under microscope didn't find anything unusual. Board only recognize charger sometimes, I´m trying 2 different 60W original chargers and a power supply with a original cable. I have to connect between 10 to 20 times the magsafe to get recognize...

Problem is macOS, thanks

Hi, macbook came with video problems, when power up it shows the apple logo, when booting progress bar is about halfway, video start looking funny, like image is double, then the cursor arrow shows up and background image goes and come, but arrow or loading cursor the multicolor circle shows...

Hi, Board came with a little speck of water damage, only caps C5002, C5010 and C5017, near SMC, where damage and nasty, charger didn't have light and no fan spin. I change the 3 caps and now board have light in charger, and fan spin, but no image in screen or external monitor. CPU gets hot, but...

Is a 60W original charger, but the cord was replaced, works with others boards, but that was my problem. Thanks

Yeah, my bad I forgot to change it after last work. PPBUS_G3H is 8.16V, was 8.56V before changing the SMC. Will try another SMC and check ISL. Thank you.

PM_DSW_PWRGD = 3.40V SMC_ADAPTER_EN = 3.40V PCH_DSWVRMEN= 3.21V PM_BATLOW_L= 0.03V PM_RSMRST_L = 3.26V PCH_INTRUDER_L = 3.00V PCH_INTVRMEN = 3.16V PCH_SRTCRST_L = 3.31V RTC_RESET_L = 3.31-V R1410 is good = 10Kohms PM_BATLOW_L goes to 0V if I disconnect power, and right to 0.03V when I plug...

Hi, board enter with no power problem, problem was SMC, so I order some donor boards, and change the SMC. Now board turns on, fan spins, after a few seconds shows the battery icon, with the lightning below the battery and then shuts down. In the power supply it shows consuming 0.45A at 19V...
