They will swap the motherboard. Almost no service center today can, will swap the BIOS chip. In fact most are soldered down so that's a motherboard swap. The days of a shop having a BIOS chip programmer has passed.

If there is one hope it's the CMOS battery. I will not write the other twenty names it is called by or tell how to measure it with a Volt meter. It is cheap and an item often forgotten.
