Hi:
Most HP notebooks that come with an internal battery, do not have a CMOS (RTC) battery.
The internal battery is supposed to maintain the BIOS and Real Time Clock (RTC) settings.
If you look at chapter 3 of the service manual at the link below, there is no part listed for a CMOS (RTC) battery.
If you look at chapters 5 & 6 of the service manual, there is no procedure to remove and replace the CMOS (RTC) battery.

You're very welcome.
It's possible that you need a new battery.
I would run the battery diagnostics test (F2) in the BIOS and see what it reports.
