Laptop driver missing problem

Neither do we. Those are very generic descriptions.

If you would provide more details we might be able to help. Key issues are
What hardware do you have?
What OS are you running?
What did you do recently that these are missing - install a new OS?
Do you know how to use the Device Manager to get the hardware / vendor IDs? If not, we can walk you through it.

Generally you can get drivers from the laptop manufacturer's website - for your specific model.
