I received a 2013 Macbook Air A1466 820-3437-B motherboard with serial number C02L6GQ9FSV8 that came in WITHOUT a bios chip. I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD. I've flashed a ton of bios but still same problem. Windows installation works with this Macbook but never a mac installation. Unfortunately, since I didn't receive this macbook with a bios chip, I don't have the original bios. What can I do now?... -
Hi everyone
I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76
Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
There's also an extra OTP Secu.R... -
Hi
I have a MacBook Air that was completely dead on arrival. During inspection I found a shorted capacitor near the SMC, which appeared to be the main fault. After replacing the capacitor, the short on the rail was cleared. The board then started recognizing the charger, charging normally, and the machine powered on. Initial testing outside the chassis showed normal behaviour.
However, after full reassembly a new issue appeared. There is no boot chime and no image on the screen, only the fan spins. The power button responds normally, it powers on without the charger connected... -
Hello all,
Working on my wife's 13' Macbook air. It's been in a box since she upgraded but I figured it could be good practice.
Details:
Macbook 13' A1466
Board (820-3209-A)
Battery OEM 7.3v 50Wh 6700 mAh (020-7379-A)

I don't know how to test the voltage on a MacBook battery. I just assumed it had an enable pin but the best I could read was 300 something mV poking around the battery connector.
It's an older model and it is very likely that battery has become...
