It does boot sometimes, but only after hanging for way longer than is normal for a A1398 of this vintage to come to the logo. Half of the times I try to boot it just gives me the question mark folder! I tried the usual SMC and PRAM resets, and I ran First Aid when the machine did decide to boot, but first Aid did not repair anything on the SSD, but came back with SSD is OK. I booted of external drive, and it did boot then.I reseated the SSD, looked at the connection under the scope. Looking clean.I switched to another known good SSD blade, same issue. I tied Safe Mode, but it hangs at login screen, lets me type my password but then nothing. Ran ASD EFI , came out fine. Tried to run ASD OS, hangs. Will boot after a PRAM reset, but then the next boot again, just the folder! Anyone have any clues where to even start?

History? Liquid damage? Discrete graphics or Integrated graphics model?
Stoppped booting from external drive as well or I misunderstood?
Happened after an update? Someone messed with EFI?
Just to rule that out I'd try to flash the EFI with a known good dump and (properly) cleaned ME region.OpenBoardView — https://github.com/OpenBoardView/OpenBoardViewComment
