JUST UNPLUG YOUR DEVICE FROM FROM OUTSIDE LIGHTENING ACCEPTABLE WIRING!! hell i never trusted a surge protector, i've lost 1 TV and 1 radio (not cable) just plugged into a rather expensive MOV surge protector, it blew them up, not the MOV. Usually it doesn't take much of a voltage increase to blow newer electronics(yep they're crappy just like cars now a days, they don't know how to make anything worth a sh**) especially PCs, I've found the ONLY way to prevent that much juice from blowing something up is just disconnect and isolate all connections, unless you're on a UPS or battery backup, then disconnect it from the power source anyways. Atleast in a UPS you have some sensitive electronics to fry before it fries whatever is connected to it.
