A month ago I bought this surge protector for my new computer. A few days ago there were power outages (I think two - the power went out, then on for a short period of time and out again). A few hours after the outages I noticed the LED for Surge protection isn't on. I tried the surge protector in another plug, but the LED was still off. Should I go and replace the surge protector or is it possible that only the LED isn't working?
