Yeah, that’s what I was getting at in my reply. I did the same thing to my M60-a. Wire from diode to the hotswap arm fixed it.
The other thing is trying to fix the little flaps inside the socket that sometimes become too flattened to make contact with the switch pin. I’ve had to do this a few times with my IGK61 board. Just push them back towards the front with sharp tweezers. This might be hard to understand without having seen the issue in person.
Both of these issues are the main reason why a lot of makers hesitate to jump to hotswap. I personally don’t mind a little fix here and there, but it’s quite the deal-breaker for someone without the tools or experience to repair it.
