RE: Power settings resetting and removing passwords
I know of no way other than possibly creating your own power plan as suggested.
I do support on other forums and don't recall seeing this problem posted, yours is the first I've seen.
The forum is going down (to read only) for forum software update (change to a different forum software) on 1/5. This is probably the last I can respond until the forum comes back up (eta 1/10).
I don't think its a "Dell PC" problem, more some software.
You may want to consider pursuing this on the tenforums.com and see if someone there can offer anything.
