RE: Optiplex 780 small form - wont start, solid amber light, codes 1 & 2 No expansion cards

Not even a PCI-e x16 add-in video card? 

If you have an add-in video card, try reseating it in the slot. Or remove it completely and use one of the 2 onboard video output ports (VGA or DisplayPort).

A solid amber power button could also be a power supply problem.

You can try clearing BIOS:

  1. Power off, unplug
  2. Press/hold power button for ~15 sec
  3. Open case and remove motherboard battery
  4. Press/hold power button for ~30 sec
  5. {Reseat add-in video card, if not already done}
  6. Reinstall battery - use a new one: CR2032 3-volt lithium ion battery, ~$2.00
  7. Close case and see if it boots now. Be sure to connect monitor to the right video outputs. If you have the add-in video card, the onboard ports will be disabled.

Or just return it and get a full refund! emoticon.Wink.title
