Thanks. That is what I figured, but I always like to be surprised I am DIY-capable and have built a few and repaired many. I am not interested in attempting to replace soldered/floated components, but am very familiar with other board and component replacement. It looks like they are going for so cheap that it will be unlikely that I can find parts cheaper than another system, but my is the top of the line, so I at least want the i7 so I can use my RAM, NVMEs, etc.
My 13 R3 was plugged in sleeping, connected to my AGA (Alienware Graphics Accelerator). While I was out of town, the power went out and came back on a couple of times. My spouse reported a pretty loud noise and flash from the transformer near us. When I came home the 13 R3 was powered off. I had it plugged into the 300W power supply and the blue light on the connector was flashing. It wouldn't power on. I unplugged everything, plugged it back in, no joy. I tried my 180W power supply. When I plugged the PS into the 13 R3, the green light went out. The 13 R3 would not power on. I opened it up, disconnected the battery, held the power switch for 30 seconds, reconnected the battery, and the 13 R3 would not power on. I reconnected it to the 300W PS. The light was solid blue before I connected it and flashing blue after. I disconnected the battery, held the power switch for 30 seconds, then plugged the PS in. Same. I assume it is time for a trip to Dell for repair, but thought I would solicit other ideas to try if warranted. Thanks.
13 R3, AGA, power outage, no power
