Unless the person in question opened the laptop considering it is true he said there is no cpu in it. He or someone would have to unsolder the chip from the motherboard because it does not fit in the board the same as a desktop motherboard. Also if the chip was unsoldered from the board I would assume it would damage the boot up process and not allow it to power up at all. But I admit, I have never heard albeit rarely anyone to replace a cpu on a lappy. Not to say it couldn't be done.
no all CPU's are soldered to the laptop motherboards (in fact none of mine have been)
