Thanks duke the issue was in fact Q6060. I removed it and noticed one of the pads on the chip were gone and the same thing happened with 2 more chips that I pulled from donors. I found a clean one and now the fan is working as it should. Thanks you can mark this as solved.

I ran ASD and there were no errors except on the fan section. The setpoint said 1200rpm and the speed was 6059rpm. I checked SMC_FAN_0_CTL and it was again showing 0.05v. What voltage should it be at? Resistance between SMC_FAN_0_CTL and PP3V42_G3H is around 218 kohms I just measured...

Okay I put flux on the SMC and heated it up but not to the point of it being reflowed. Also, when I looked around the corroded JTAG connector that I previosly removed I noticed that R6115 was missing from the board so I may have knocked that off when I initially removed the JTAG. I put R6115...

I tried with a fan from a 13" Macbook and it does the same thing. Are those fans compatible or do I need to get a fan for an 11" machine?

I checked the traces that go from Q6060 and all of them were fine. I put another Q6060 and R6061 on the board but still the same issue remains. I measured SMC_FAN_0_CTL on pin 2 of R6061 and it still just pulses very quickly at around 0.85v then just stays at 0.05v. Pin 1 of R6061 is a steady...

Diode mode of TACH (Pin 2 of J6000) is 0.635v I have the voltage measurements of R6065 above and the resistance of it shows 43.5kohms I attached an image of the RPM profile. I believe the reading was 6131 RPM.

I have this liquid damaged machine. Initially the fan spun very fast and was making the 3 beeps Ram sound. I took the machine apart and noticed the underside of the fan was sticky and had liquid damage. After the board was ultrasonic'd the machine boots fine now but the fan issue remained. In...

I removed that chip again from the board and cleaned the pads and now I'm getting a quarter fan spin that keeps trying to turn on every 5 seconds. Can someone take a picture of the positioning of the U7760 chip on a donor board so I can make sure I am putting this new chip facing the right...

Okay I replaced U7760 with a new one from digi-key(MAX15053EWL+T) and now I has no fan spin and the 5v/3v3 S3 and S0 rails are missing. I checked for pm_slp_s4_l but there is only a quick pulse when the charger plugged in and then 0v afterwards. The 1V8_S0 line is not shorted to ground in diode...

I am getting 3.28v on C7780(PP1V8_S0). Do you know why it would be so high when it should be 1.8v? Could it be due to the U7760 chip I put on? I didn't have a stencil to reball that chip so I just put solder on the pads and flowed it onto the board.

For some reason when I measured PP1V8_S0 on C7780 & C7762 and get 3.28v. On R7760 I get 3.26v on Pin 1 and 1.09v on Pin 2. Not sure but these measurements don't seem like what they should be. I get 0.75v on PPVTTDDR_S3 but 0v on PP0V75_S0_DDRVTT PP1V5_S3, PP1V5_S0 and PP1V05_S0 all have the...

I only get 0.13v on ALL_SYS_PWRGD and 0v on PP0V75_S0_DDRVTT. I figure it might be an issue with the U7760 chip I replaced. I am only getting 0.9v on both sides of R7765 and 0.6v on C7764. I tried putting 2 other U7760 chips from donor boards but the fan wouldn't even turn on and the cpu didn't...

This board had a small amount of liquid damage around the SMC area and in that area on the other side of the board I replaced several components around that area and have ultrasonic'd the board. Initially I started by replacing Q5030/50, R/C5329, C4901/20, R5488/89, C5489 C/U6901, C7782, U7780...

This board had liquid damage only on the bottom side of the board from the lp8550 across to U1950. I replaced the following components initially to see if I could get it working. U1950 + surrounding resistors/caps, Q8150 + resistors below it, C6100, U1900, C1910, C5010/17, C5002/07/08...

Forgot to say that after replacing the keyboard controller chip it is working fine now.

https://www.rossmanngroup.com/boards...ys-not-working This previous thread was marked as solved after I replaced the kbd connector because I thought that solved the issue. When I put the machine back together and booted the OS again that same row stopped working then after about 10 seconds it...

Replaced connector and now keyboard is working fine. The Backlight cable wasn't plugged as I thought it was because i mistook the microphone cable for the kbd backlight cable. Everything is all fine now. Thanks again Duke.

Before removing R7940 it shows 0.545v on both sides in diode mode. With R7940 Pin 1 is showing 0.58v in diode mode and Pin shows 0.585v.

I have this board that doesn't show any signs of liquid damage. It shows a green light on the charger when plugged in but nothing else. PPBUS_G3H is 12.59v and there was no voltage on any of the S5 or S3 rails. I traced the issue to U7201 where there was 0v on PM_SLP_S4_L and SMC_PM_G2_EN. I...

This is the same board that I just got help with fixing due to internal speakers not working. https://www.rossmanngroup.com/boards...th-sound-works That issue is fixed but now I am having issues with a row of keys that are not working. "zxcvbnm,." those keys are not working and I plugged in...
