Hi,
The metal jacket around the micro USB may have shorted out the +5VDC power supply to the USB port and also it may have affected the USB controller by connecting +5V to it as well on the USB data lines. I don't know why it would affect the rest of the laptop and not only the USB ports and USB controller though.
Perhaps the whole +5V supply in the laptop (derived from the battery (or the adapter) may have been affected.
The laptop has various power supply rails of different voltages in it.
-You may have to open it up and check if you can see any obvious signs of damage. Hopefully perhaps only an onboard fuse may have been blown.
+You may have to open it up and check if you can see any obvious signs of damage. Hopefully perhaps only an onboard fuse (or fusible link) may have been blown.
If this is the case once the +5V is restored it ''may'' work again, but possibly not the USB ports as no doubt the USB controller would have been fried.
