Do you need to change the battery for cmos for your laptop?

Computer

If you look at a normal desktop, there is a phenomenon that the cmos battery is on the main board, so if you use it all, the PC time is not right.  Does the laptop also have a cmos battery?

Or is there a separate battery for the laptop?

pu2. It's in my laptop, too. If you use it for about 7 years, the battery might run out
