A while back I posted some questions in regard to surge protectors and power supplies. I helped a friend of my sister's file an equipment claim, on computer parts damaged from a presumed lightning strike on her computer. The computer was plugged into a surge protector with equipment warranty, so, we filled out the claim. Here is what happened: The company examined the surge protector, and, came to the conclusion that it was not damaged, didn't look like anything was even plugged into it. However, this company did offer some compensation anyway, even though they would not admit their protector was at fault. AFTER learning more information about properly grounding a surge protector, she was lucky to get that offer. Looks like, in her case, the surge protector was not properly grounded, thereby offering no protection to her computer ,and, voiding the warranty. So, looks like those equipment warranties on surge protectors are a good deal, but, be sure and properly ground it, and, fill out the warranty card.
