Hello, First general question... why can't search the forum based on board numbers? ;-) Second, I have that 820-3437 board that someone has already reworked and cleaned so difficult to tell if any damaged has been done on it. However what I can tell is that I am getting the fan to spin only...

Hello Duke, One turns on with the fan blasting but obviously no CPU vcore (no chime). Voltage on the shorted caps is a nice flat 0V. On the other one, it doesn't even start at all. I have removed already all the big black caps but it seems it has to be a small one or the CPU now... Anyway, I...

Hi, I have that board with no apparent liquid damage but I suspect a dead SMC so before replacing it can someone confirm I did all the troubleshooting properly? I have SMC_RESET_L to 3.3V No short on SMC_PM_G2_EN I've reflowed the SMC once I have a green light. Thanks!

Hi, I have 2 boards with apparently the same issue. Short on a rail where most of the shorted CAPs are next to the CPU. I really get a 0V drop to ground, not 0.05 or something (I know that the CPU rail has a low resistance to ground) Since the schematics doesn't exist for these Mac Minis...

Hi again, I have that other mainboard which most of the times doesn't show any picture on the screen or external screen. For some reasons it will work once in a while. Backlight is working fine. We have CPU_VCORE when no pictures. Again, no apparent liquid damage on that board. Any ideas...

Hi, I have that board that won't detect the trackpad in the OS where it works fine in EFI. We also tried to plug a USB mouse and it would'nt detect it. Booting from a USB drive worked fine however. We can use the FN keys while at the login screen (lower/raise screen/keyboard backlight) so we...

Hi, I've got that board that I believe was bought from ebay quite some time ago (Yeah I know, Ebay boards are a waste of time but still...) It looked very clean, but someone has tried to rework the CPU_Vcore area thinking it might be shorted because of the small resistance to ground... who...

You nailed it! I didn't the right battery type at the time so I couldn't check. With a new battery it is working. So the short went pretty deep or it came from the battery who knows...

Hi, I've got that board which had a short on PPBUS_G3H. One cap near the CPU was shorted. Found, replaced and it looked like everything was fine. However I now have another issue... the battery is recognized and apparently charging but it doesn't stay on battery. PPVBAT_G3H_CONN is 8.6V with...

Hi Duke, Thanks! It was a broken trace between the quartz and the clock chip. 3 cycles fan spin restored and board alive now. cheers!

Hi, That's my first post on this forum, and having big hopes about it ;-) Kidding... So I have that 820-3437 board which starts but only get the fan spinning once. Then full blast and I feel that the CPU is getting too fast. I've the CPU rail PPVVC_S0_CPU which is a stable 1.78V (I was hoping...
