Chosen Solution
Hi techies, I bought a logic board which boots only via USB, but when connected to internal SATA it will shut down after a few seconds. I suppose it might just have been the SATA connector in the sellers machine, but he claimed it was not just that. If anyone knows if there is a known issue with the A1297 and HDD connectivity, other than a broken SATA connector, maybe I could have a look at that area on the board while it is still out of the case…
Is it any HDD connected to the SATA connector or have you just tried the one? It might be the hard drive itself. I’ve never heard of this being a recurring problem either
Check the formatting of the drive and see if it is GUID. Also it the drive has been subjected to an attempt at installing High Sierra or Mojave it may have tried to impose APFS formatting if it is a Hibred or SSD drive. While even a drive formatted MSDOS will boot externally if it has a Mac system on it, it will not boot internally. PS am eager to see your solar setup.
@mayer mayer , I have the pictures of my solar stuff on my profile page now. Did not get to the Sata issue here, I am fixing about 3 machines right now, most of them mired in the proverbial unknown…
