How can I know if someone change my laptop parts ? Is there anyway to find it ?

Hi,

Most of the time at the back of your laptop where the screws are there's one screw that will be blocked with a warranty sticker. Also inside your laptop if there's no warranty sticker outside there should be warranty stickers on the parts where it's removable.
