Hi experts,
 I have two Dell Optiolex 3020 and I'm having trouble turning them on. I press the power button a few times and I get no response at all , then after a few tries I get a blinking Orange Light blinking. I then unplug the power cord for a minute plug it back in and it powers on ok. Then I turn it off and it does it again. Power supply going bad?

According to the Dell manual, blinking amber is supposed to indicate a bad power supply.  I have experienced the blinking amber myself and as you have discovered, unplugging the PC for a few minutes seemed to fix it.  Those PC's that exhibited this behavior continue to run as normal so I'd chalk it up to a buggy sensor of some sort.
 
If you are getting a 2 - 1 blink it may mean the motherboard is going bad.  If the equipment is under warranty, time for a Dell fix.

You should also see if you have a lot of USB devices drawing power.  Others have noted that with the removal of high draw USB devices such as printers, the problem went away.

If the machine isn't under warranty, open the PS and look at the capacitors.  See if any are swollen or leaking.

You can also try swapping the PS and see if that helps.
