RE: 50g Warmstarted in the future!
HI TravisE,

I tried it with my HP 50g and it did exactly as you described. I removed all 4 AAA batteries @ 19:56 and reinserted them at 20:01. Then I powered on the unit and viola, the clock displayed 19:51. However, my unit didn't warmstart (as it should) and my WSLOG was unaffected.

I believe this to be a solid hypothesis. In my case, the next scheduled "wake up" was my alarm (even though it didn't ring) & in your (TravisE's) case, the next scheduled "wake up" is your automatic power on performed by the HP 50g approx. every 3 days or so. I have no knowledge about the emulated saturn CPU part of the 50g so I cannot comment about it (except that I should learn about it!).

Either way, both our 50g units performed a warmstart, whether intentional or not, and reported a future WSLOG entry. There might be a consistent behavior to document here.
