Prima di smontare chiedo di sapere se per questi modello la batteria tampone CMOS che mi crea "error 502" si trova sotto la MB o invece, come qualcuno scrive, è attivata nella batteria vera e propria. Grazie

Your notebook does not have a CMOS/RTC battery.
The main internal battery also serves as the CMOS/RTC battery to maintain the BIOS and system clock settings.
Below is the link to the service manual:
Maintenance and Service Guide HP 15 Laptop PC
Chapter 3 has no CMOS/RTC battery part number.
Chapters 5 and 6 have the component removal and replacement procedures.
You will find no procedure to remove or replace a CMPS/RTC battery.
