If it has a warranty issue then you would just put the original HDD back in and send it for repair. Most laptops have a hatch to access just the HDD, so it's pretty straight forward.
Doesn't work. They can tell. Some have security seals as well.
If you buy a car, and change the lights/wheels/gearbox, and engine breaks down, how is it that they decline warranty for the engine?
Obviously if there is possible damage from the changing of drive then warranty declined. But most low end laptops have a drive bay that is completely separate from all the mobo components, it's about 10 screws and a rigid socket.
Anyway, I've always bought Dell and always changed drives around and when there's a warranty issue (usually LCD screen, SD card slot, etc) they have no issues there.
