Its specs

https://support.hp.com/au-en/document/c05803124

It does NOT have RTC (or CMOS) battery. Do you keep power for its main battery

if I power down for the night some times I get the CMOS reset when power up, or if i unplug for a long period time I get the CMOS reset?

Normally when the battery is totally empty after a number of hours (can be overnight).
