The board says 2.4GHz 4GB which matches what the bottom plate serial number is. It is a 2013 Macbook Pro Retina 13" . The serial number in the bios / about screen is...

Here programming socket you can build for yourself. Probably don't need the resistors and cap for a programer, but this one I have hooked up to a Pi as I had that lying around. It can write and verify a bios chip in about 15 seconds if you have the file using the open source flashrom program...

Anyone know where to get one? I downloaded one from https://www.ghostlyhaks.com/downloads/efi-repository But it didn't work.

I have a board that was liquid damaged, stuck in boot loop. I installed a new bios chip and now it chimes and will start booting. Any attempt to load macos results in progress bar to 3/4 then slows down greatly, it eventually gets to the end of the progress bar and then just stays there. After...

Video out to screen, no backlight, fuse was blown I have traced it back to Q7707 and all the pins look correct other then pin 5 EDP_BKLT_EN which is zero, The schematic says this goes to a pin on the CPU, Could just that pin on the cpu be damaged as it appears to work fine other then backlight...

I have an 820-3437 that had liquid damage. It was pulling no current and no led on charger, I cleaned up corrosion U1900, removed and cleaned it and replaced. I now have PP3V3_SO and PP5V5_S0 and am pulling 136ma on the power supply. My vcore is only .085v, I can't seem to find anything pulling...

Anyone think of a way the dc in board can be bad and cause the cpu to overheat?, usually boot up one time then freeze up and not work again till it sits and cools. Either that or I am very unlucky with boards as I have had 3 do the exact same thing... This one is pulling 1 amp through the power...

After fan stops pulling about 24ma from the charger. Going down the power rails I have everything till PP5V_S4RS3, on U7501 it is 5V while fan spins, then down to zero when fan stops on pin 2. It looks like something stops telling it to turn on. Any suggestions?

On Q7910 I have 3.3v on pins 3 and 4, but pins 1,2,5,6 are all zero and not shorted to ground. It looks like Q7910 is bad, anything else I need to check? Board is pulling 20mA from charger.

First I will preface this with I am new to macbook repairs, I have the above referenced board that was showing fine diagonal lines, get almost to desktop then reboot, hot in center of board. I took this to be the graphics chip problem, since I am new and need practice I took the heat shield off...
