I am just curious and have never seen or heard of it being done other than the actual manufacturer of the company. Lets say you have a laptop and the motherboard is dead and you buy the same exact 100% motherboard it had and it is installed correctly and right. Would it work? Or does the Motherboard somehow sense that the Ram and HDD is not what it was originally made with? I have always wondered this and can not find answers. When i search for this all i see is people asking if they can build their own laptop from scratch which is pretty much impossible due to the case of laptops only fitting the motherboard, Ram, and HDD they were made with.
