Poweredge R310, no power

Hi, thanks for the response.

I haven't reseated the processor but I can do that, it has a non redundant but I know that works..  

there are no error codes on the lcd system, the only lights are the one on the mother board and the ID light.

 I have removed the ram and still nothing, it just doesn't turn over at all.  

unfortunately the warranty has expired.

The other step to try is to hold in the I button on the front for 5-10 seconds and it should show what step it is on or if it is getting anywhere, but based on what you have described it probably is the motherboard.

It could be a bad motherboard or processor. Have you tried just a single memory stick? Can you reseat the processor? Is the system under warranty? Are there any error codes on the system LCD? Does it have a single or redundant power supply configuration?

held the button down and nothing at all.  oh dear, I guess the chances of getting a board are slim to nothing

They aren't hard to find:

Check the cables from the control panel with the power button to the motherboard as well, sometimes reseating this will help. You can probably buy the replacement board from sales or call support and pay the out of warranty support fees. The server is a new enough model that parts should still be available.
