When a laptop internal device fails , what three options can you use to deal with the problems?

The three options one may take in case an internal device fails include
1. return the machine to the service center for repair. the manufacturer of the computer have better knowledge about their devices and can fix problem without any difficulties.
2. the other option is one can substitute a functioning external component for faulty internal component.
3. third, one can replace faulty component.

Ithink its because more have died recently than in the past.
