As far as I can tell, this sub forum is the most pertinent for this question:

Do you protect your electronics more from power spikes and surges - during, say, a thunderstorm - by flipping the master power ON/OFF switch on a standard power strip w/surge protection to "OFF"?

I understand that the safest thing to do would be to unplug the appliances connected, but just out of curiosity, would flipping the switch to "OFF" help? I'd think that ON/OFF has a moderate effect, since if the electricity goes to like 6000 V on the wall receptacle, the connection would arc across the switch anyway.

Also, how safe is it to use a PC connected to a UPS w/surge protection during a thunderstorm?
 
With one caveat, unplugging and switching off will have the same effect on surges/spikes--both will completely eliminate the problem. The caveat is this: if lightning strikes your house, the switch in your surge protector won't do much. If you unplug your equipment, you have a slightly greater chance of saving it, but you have to unplug every cable that goes outside. That includes power, coax, phone lines, whatever else.
 
Yes, it's best to pull the surge protector plug and any other peripherals from the wall socket as Mohonri has noted. Don't forget the cable line if you have cable broadband. I lost a computer to a lightning strike on the cable line, which went right through the modem into the nic/motherboard. Cable company replaced the modem with apologies, but wouldn't do anything about my computer.
