Swapped out the PSU with a known working one, upon plugging in the pwr cable, the pwr button back-lit GREEN and there were no longer any numeric codes blinking. Initiated a boot cycle but INTO Setup, confirmed drives are showing up, memory as well. Booted again, F12, into on-board diags, and everything passes the quick test. Might suggest the blinking 1 & 3 could have been residual effect from the failed PSU to begin with. Looks like blinking Amber pwr button supersedes the diagnostic numeric codes, at least until you remedy the power supply unit. Answer from Towster on dell.com

Dell Diagnostic Indicators According to the diagnostic indicators, lights 1 & 3 indicate a RAM problem. Blinking orange power light indicates a failing or failed PSU. I had a RAM problem with my 755 last year. Lights 1 & 3 lit up and power button light was a steady orange. How's the CMOS battery? A low battery can cause all sorts of bizarre problems. Replacement to rule it out is cheap. I'd try reseating RAM chips one at time, starting with no RAM. See if the error repeats. Remember to unplug power cord in between reaseating chips. If the error remains unchanged, I'd have to suspect the PSU. One of our other Rockstars or experts might chime in too. The light combo you had I don't believe is normally one seen together. You may also use the 'Get Help Now' option at the bottom right to chat with a Dell technician right away.
