With PC's, this is possible, I know. But > laptops, I have no idea. Possible, yes, but in a notebook it will be soldered to the motherboard, so replacing it would require hot-air rework equipment and experience. Replacing the motherboard is simpler, although sometimes not simple, even if you have done it before. Neither method is likely to be practical. The term is "BER": beyond economic repair. Replacement of the system will be cheaper.
