Widowmaker for your time.

So I have an HP 15 Notebook in need of a new hard drive. Issue is I’m not sure if the drives I’m looking at are compatable with it and my research hasn’t given me the answers I’m after. I’ve heard some folks on my search say that basically all hard drives are the same and should work so long as they’re the “thin” kind like mine was, but I’m not sure. Anyone here who’s actually torn Laptops/PCs apart? I’d like to hear from someone who actually knows what they’re doing unlike me.
