Hi Maz,
Welcome to Sony Community!
We're sorry to hear about your laptop. Are you getting any error message? What was the last time that it works? Is the driver missing from device Manager or it's there but it's not working?
I will provide you a couple of links to try: https://us.en.kb.sony.com/app/answers/detail/a_id/30406/p/48903,49902,55369,55388/c/65,66/kw/cd%20%20dvd%20not%20detected
