exactly 0.10 milliamper i have say up the voltage on big coils i have : 5v L7670 3V L7690 12V L7030 0V L7400 0V L8410 0V L8100 0V L7210 0V L7220 0V L7230

what voltage you need ? because i have try the nand voltage and its good

I compared everything and I have only the pin 36 “LPSR_EN_LB_L” that instead of having 0.470 I have 0.549

J9600 is good and no trace of oxidation and the customer said it just happened

I have an a1706 820-00239 can't find the hard drive, no trace of oxidation we go in to do the installation, hard drive not found we measured all the voltages around the nand I have the PP3v3_2v7_nand_VCC: 2.69V PP1v8_SSD_Cold: 1.8V PP00V9_SSDREG : 0.9V Do you think the problem is with the...

thx for the help i have found RTC_RESET_L have a problem i have repair is working /

I have an A1466 820-00165 motherboard it doesn't turn on, doesn't repair. the green light comes on, then turns orange, on the power supply it consumes 0.020ma. I have the PP BUS, I have 8V, I have 3.3V on P3V3-S5_REG-L On the P5V_S4RS3_REG_L 0V I have no short circuit on it (value: 400). I have...

ok thanks, I found where the problem came from, it was the U5110

Hello, We have a computer A1466 820-00165, it does not start, the led on the charger does not light, on the motherboard there is no trace of oxidation and on the power supply it consumes 0.010ma. We have voltage P3V42G3H (ok). We've changed the charging circuit on the U7100 and U5000 and same...
