Solid Green light unable to boot

My nuc won't boot/turn on
All I get is a solid Green light where the blue light used to be.

I've dismantled it.
Swapped the ram, removed and reseated the msata card, removed and reseated the WiFi adapter.
Even tried a different power supply.
Nothing seems to work.
Please help

Unfortunately, there are a myriad of issues that may be responsible for this issue.

Let's start with the simplest: Is the power button working properly? Try pressing it quickly, over and over (but not too hard), to see if it is getting physically stuck and you can free it. 

Next, that green LED simply means that the NUC is receiving standby current from the power supply (PSU). This is usually a reliable indicator that the PSU is working, but I have seen cases where the PSU has suffered a failure and cannot provide sufficient voltage/amperage to support operation. My next suggestion would thus be to try another PSU.

I will stop there. Let us know how it goes...

You may try to replace the CMOS battery. Since the battery is located on board upper (invisible) side, you need to remove the board from the NUC case. This video clip will show you how to do this.  You nee to buy a CR2032 replacement battery with wires and connector. Similar to this one . Before installing the new battery, check that the wires polarity is the same as in the old battery. You may also prepare a new battery using standard CR2032 battery and add connection as described in this CMOS battery hack.
