As someone who's been in electronics servicing for well over 30 years, I can attest that connectors are the cause of many mysterious faults where nothing else was wrong with the equipment. Unplugging and replugging fixed many faults, and using contact cleaner helps stop the problem from rapidly recurring. But use proper contact cleaner, not *ordinary* WD40 (it's corrosive, and will cause worse contact problems down the track, not to mention how horrible it is the the lungs). I used to encounter many connector problems with PCs years ago (when I frequently fixed other people's computers) because the case wasn't rigid enough. When people moved the box about, even by small amounts, the chassis would twist and it pulled cards partway out of their sockets. I had one that pretty much had to stay untouched on the shelf. Thermal expansion and contraction also walks connectors apart. One of my early computers had a very solid case, and it had a metal bar between the front and back of the case, and another that was screwed down over the top of plug-in cards to hold them firmly into place. Modern SATA drive data and power connectors are not very good, in my opinion, compared to the older style. They had a much tighter grip. Some of the better SATA cables have a metal catch to stop them slipping out. -- uname -rsvp Linux 3.10.0-1160.71.1.el7.x86_64 #1 SMP Tue Jun 28 15:37:28 UTC 2022 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
