I am well aware of the shared bandwidth between M.2 drives and some SATA ports. I have avoided any affected SATA ports and as I stated, I have tried other ports as well. I have now tried another "known good" SATA cable with the same results. I should also mention that if I substitute a WD 1TB hard drive for the Optical Drive, everything works fine. I can let the computer go to sleep, restart the computer, etc. without any problem
I don't know what "clean tips" means. I have previously built 11 computers and regularly read various informative web sites.
