I would start by searching with this link:

HP usually has pretty good support documents.
Most laptop CMOS batteries these days are really just RTC (Real Time Clock) batteries. Much of today's CMOS is non volatile.
Usually the CMOS/RTC battery can be found under a small removable cover on the bottom of the laptop or under the keyboard. The keyboard does not usually require major disassembly, you just need to know the trick to release the keyboard latches on most machines.
Do not start by trying to fully disassemble the machine, this may get you in a tough spot.
