Hi, the board doesn't turn on. I post these voltages. PP3V42_G3H=3.4V PP3V3_S5 = 3.3V in u7940 RSMRST_PWRGD = UNSTABLE S5_PGOOD_CT= 0.3V PP3V3_S5 =3.4V PP3V42_G3H=3.4V

hello. I have a 3115-b motherboard. Apparently no corrosion damage. Green light on charger after about 10 seconds, pulling 0.04A. missing PP3V3_S5 (0V) without short circuit to ground Voltages for U7200: 16 - 12.29V 13 - 2.12V 3 - 0V 8 - 0V 17 - 0.4V 6 - 0V VOLTAGES for U7941: 4 -...

Macbook keyboard and trackpad not working in OSx A client brought me a Macbook A1502 with a non-working keyboard and trackpad, but when I decided to test them in another OSs (Linux MX and HBCD in my case) and they work perfectly. I tested them in High Sierra and Big Sur in safe mode but they...

I have a motherboard (820-00431-002) that has a missing resistor. I would like to know the value of that resistance. I can't find that information anywhere. The resistor is connected to the ISL6372 pin 6 chip. I'm going to post the photo of the board with the missing resistor. Can someone help...

hi. I have this macbook retina 2012. the problem is that it restarts when the apple logo is loading. I disconnected everything on the mainboard and it still reboots. Before this, the macbook would shut down because it had the tunderbold port shorted (bent the pins). the Hard drive does not...

hi i have the situation very similar to the rossman wiki. Green light, no light: 0.05 A on power supply. P5VS3_EN_L = 3.42V (pin 2 of Q7221) P5VS3_ENTRIP = 0V (pin 6 of Q7221) When Q7221 was removed, PP5V_S3 was good (5V). PM_SLP_S4_L = 0 V (pin 1 of Q7911) in my case the consumption is much...

I have a situation similar to the example of the rossman wiki. Green light, does not turn on - 0.03A power source ------------------------------------------ PP5V_S3 = 0V P5VS3_EN_L was 1.42V to ENTRIP1 on TPS51125 (U7200) When Q7221 was removed, PP5V_S3 was good (5V) PM_SLP_S4_L = 0V on pin 1...

Hello, When it got here the first time Trackpad was not working so we inyected voltage to u5805 , Got hot , after that , the mb stopped turning on. have this Right Now - Green Light on - PSU consumes 0.01A - PP5V_S3= 0 - P5VS3_EN_L=3.42 , but P5VS3_ENTRIP=0 - 5V3V_REG_EN= 3.22 , but...
