Hi Fred, I see no-one has responded to you so I will chime in with what I know.
A few more details about what you actually see and hear when you press the power button would be helpful. What you should see and hear is an almost immediate relay click and most (all?) LEDs turn on. Fractions of of a second later the display backlight comes on, then fractions of s second later the display comes alive and you should hear audio. This machine boots up fast, thank you, engineers at Elecraft. If on the other hand, you see "CPU LD" (or something similar) in the display, the software has decided that something is wrong with the application software and decides to stay in the bootloader (modern firmware always wakes up up in the bootloader and decides where to go from there). That would explain why your only recovery is to reload the firmware. I am starting to guess now and it's not always a good idea. One explanation is that there is actually something wrong with the application firmware (corrupted to some degree). But this seems improbable since you can consistently recover by reloading it. I assume you are turning the radio off by using the power button. Another possible explanation is that the CPU starts executing before the hardware has come up completely and thus erroneously concludes that the application firmware is corrupted. I realize that none of these ramblings is a direct help to you to recover from your situation but I am hoping it may trigger others to have an AHA experience. BTW, the battery is not essential to the K3 operation. It just powers the RTC which is not very good anyway. I have plenty of better ways to tell the time of day.
