Sorry, I can’t offer any help, it’s been 40 years since I did 6052, on a BBC B!! Would love to know what your interest in it is?

I use the hybrid: suspend to ram, then after 2 hours, automatically suspend to disk - in the final state it uses zero power. And, if you have encrypted your drive (you DO encrypt your drives, right?!) then you need to enter passphrase on resume from hibernate, so safer if device was nicked.

I agree with negligent! Using suspend to ram for extended periods, eg nightly or over weekend will kill your battery life.
