Traditional motherboard has fuse for Keyboard and
port to prevent over-current or shortage. These fuses are soldered onboard that
when it is broken (function as protecting the motherboard), user still cannot replace it and the motherboard is still malfunctioning.
With expensive Resettable Fuse, the motherboard can be resumed back to normal function after the fuse had done its protection job.
