My old faithful beloved Intel NUC5i5RYB fails to power up. It's been running solidly 24/7 for around 6 years so I'm unwilling to commit it to the great silicon grave in the sky just yet.

Thought I would talk through the process of what I have tried to date to rule things out in the hope that someone will know what to try next.

Initially followed this:

and also this

So what have I tried.
1. Checked the power supply (reading 19.6v)
2. Checked the CMOS battery (reading 3.4v)
3. Wired up the fan to a 5V power supply and it spins like a beauty
4. When plugged in USB sockets are powered

So making an assumption that the switch was faulty, as I didn't know where to turn to next, I took the following resistance and voltage readings for all the switch feet combos I could think of:

Does anyone have any idea where to turn to next or if they know of someone good at repairing these for a fair price?

I had the same problem with one of my NUC's, I used carb cleaner worked into the switch. (spray can from any motorfactor)
That fixed mine, if it's the switch issue with yours.
