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