Unfortunately, your best option would be to contact the laptop manufacturer to see if they can provide them to you. If not you are going to have to do some searching on Google or some driver site in their archived records. You should always use the drivers from the laptop manufacturer because they are created by/for that manufacturer and are unique to that device.
Cheers and good luck!
