I take it you want a driver for the optical drive? That is included in the operating system and doesn't need to be upgraded or replaced.
Does the optical drive show up in Device Manager?
If not, check in the bios of the computer and see if the optical drive shows up there. Look in your manual for the procedure to access the bios on your laptop. (on an HP it may be F1 as you boot up, before Windows loads)
By the way, you don't have to change anything in the bios, you're just looking to see if the hardware shows up.
Let us know if you find it in either location.
