820-00165-A, boots fine, no with SSD

[Max7]

Another 820-00165

When the SSD is removed it boots fine to? folder. However, when I put the SSD in it first goes up to 500-700mA but after about 15 seconds it drops to 25mA and stays there.

I am not sure where to start troubleshooting. (SSD is a known good one).

Thanks a lot,

Max

Try starting in SMC bypass mode.
Check R/U5480 and their traces.
