Not to bust your balls or anything, but it does seem that you're perhaps more concerned with this than you need to be. How often does the power fail where your DSO is? And as long as you have the screensaver set to run, I'm not sure it makes that much difference. I'm using my DS2000 heavily - it's often on all day long for days on end (and I've had it for 20 months).

Yeah, it's not a big deal, I agree, but along with not being able to unlock 300MHz, I'm just wondering if there is a hardware issue with my scope.  Anyway, I'll drop it now   ;)

There's probably a SCPI command for it - and if so, that might work. But even though Rigol has released a new user's manual for the newest v.3 firmware - there's still no new programming guide (as far as I can tell). You could try the following guesses from Ultra Sigma, since sending incorrect commands doesn't cause any harm - and the DSO will display on the screen whether it's accepted the command or not.

The :SYSTem:PON command is to set 'power on', so I'm guessing that POS or PST might be 'power status'. Try:

:SYSTem:POS DEF

and

:SYSTem:PST DEF

:SYSTem:PST DEF is correct, but it still does not change the behavior.  I'll contact Rigol and if nothing comes of it, I'll just live with it.  Now if we could just figure out what's going on with the 300MHz randomness.

I've been using my DS2000 heavily the last few weeks, and about a week and a half ago it just started to hang constantly - requiring reboot after reboot (some combination of settings - I think I was using Roll mode). It got so bad, I was starting to think that I'd had some kind of failure - but first I downgraded to FW v.2 and uninstalled 300MHz, and since then, it's been absolutely fine - not a single crash. I still haven't re-installed v.3 again to check if it was specifically that or the 300MHz option causing the problem, but I can certainly report that FW v.3 with the 300MHz option installed is definitely NOT stable.
