Traditional motherboard has fuse for Keyboard and
USB
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.
