WHAT TO SAY, IN THE ALLEGED CASE THAT IT WORKS. ALSO TRY TO RESTORE THE MAC WITH THE TWO MEMORIES REPLACED AND I GOT THIS ERROR. NOTE: THE MAC LOOKS GOOD. CHARGE WELL, IT HAS GOOD CONSUMPTION BUT GIVES THIS ERROR

Thanks. I'll do that. Can I put more capacity nands? I mean, expand the memory

Hi. all lines with red highlighter are missing. Any contribution will be welcome. Thank you

after removing U9300 and U9100 the short disappeared. My question is: can these nands be replaced? In case they can be replaced, what should be done after welding the new nands? thanks to all.

Tank you Sr. i'am wating for a new screen

0 V always on LCD_HPD_CONN and DP_INT_HPD unfortunately I don't have a good LCD. Anything else I can do? I would not like to think that the PCH is damaged

I have a 820-4924-A board, it turns on normally, but no display. It displays image to an external monitor, but its own LCD remains black like it has not been plugged in the board. L8300 5V appear in the first few seconds w/ or w/o LCD connected. PPVOUT_S0_LCDBKLT 0V always. Just 5.1 V pin...

thank you master. that doesn't work for me. What I could see is that PP5V_S0 is missing. What do you recommend? Thanks.

thank you my friend. let me check the trackpad and order a new one to test.

I already put the trackpad cable in and checked all the pins and they look super good and clean. the FPC also looks excellent. This machine did not suffer from water damage. L / F8400 are good. Something that might seem interesting is that when the machine is on, the power button works to put it...

The customer brings an 820-00840-A because he tried to change the battery and then the machine did not turn on. Just align the battery in its correct place and the machine started and charged correctly. Once the mac was turned on I discovered that the trackpad and the keyboard did not work only...

Sorry but I'm new here. Please can you tell me where I can find those files or send me a link for it? thanks for everything Master.

All SPI Bus Series Termination resistors and traces are good. I don't have another 820-00165 that I know of that works well. I extracted the bios and saved the original .bin. Can I do a Clear ME or something similar?

OK, HERE WE GO. Only 2 pulses when I connect the charger. Approx 5s between each pulse and then held at 23-24 mA. VCORE and PLT_RESET_L is pulsing at the same time. Q8150 and U1950 look super clean. 3v3_S5 / SUS are stable. Something that I forgot to tell before. the trace between U3510 / 5...

820-00165 no power. PP5V_S4RS3 (NO PRESENT) 0.000V and diode mode 0.440V SMC Bypass mode: two fan sping two time 400mA pulse when connect charger (Orange light) Then 24mA constant 7100 Voltage whit out Battery 01-0.004V 02-19.58V 03-5.267V 04-3.326 05-1.096-1.106V up-down-up-down.... 06-0.000V...

The machine does not start with battery or without battery. When I turn on SMC Bypass mode it doesn't do anything (the fan doesn't move at all) The heatsink looks perfect and I already changed the thermal paste. The only thing I have not done is clean ME BIOS. But I tried to reflow the wonderful...

Thanks guys for all the support

PPBUS_G3H voltage without battery = 8.60V voltage without battery SCL/SDA = 3.42V/3.42V diode mode to ground for SCL/SDA = 5.53V/5.49V ohm resistance between pins 17/18 = 4.2 ohm 27/28 = 20.8 ohm

Hello guys. the macbook air overheats and shuts down in about 10 minutes or less. When I connect the charger it gives me a green light and then a permanent orange but the fan does not move. I go to the U7100 do a reflow or replacement and the mac turns on normally but turns off again after a...
