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

the motherboard take 20v and go to 0.35mA and down to 0.10mA

what do u want to say when u say :Did you test the board alone on the desk

Hello, At first the MacBook stayed on 5v I saw that the U3100 component with the thermal camera was heating up, so I replaced it, now it goes up to 20v but I have no display with the battery: at startup it rises to 0.80mA then stabilizes at 0.50mA Without the battery: on start-up it rises...

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...

But the problem doesn't come from the battery, I've already done all the cross tests that were possible and I know that my chassis is good because I've also tried on my chassis with another functional motherboard. So if you have a solution because the problem comes from the motherboard.

same thing

I've tried it externally, I get the low battery logo but then nothing. Same thing with the screen panel plugged in and unplugged. so it's the same as with the internal screen. I've tried a 96w charger but nothing changes. ( i have power supply it takes 10A and when i plug the MacBook is...
