I recently ordered this item from Amazon: 8 Way SURGE Protected 2m Extension Lead Switched NEON 8: Amazon.co.uk: Electronics And when I got it today, I spent the afternoon replacing the two old socket strips I had daisy chained to my seven electrical items, all leading to one mains socket. I figured it would be a more practical solution and gain me an extra spare socket as well. The thing is, I plug in the PC on two separate occasions ONLY into the socket I've chosen for it, and it sparks visibly as I do so. None of the other plugs did. But what puzzles me is that when the socket power is switched off with nothing connected, the light goes on and off instantly, even with different time delays between doing so. But when the PC is connected, the light will fade out more slowly when power is switched off. Is this something unique to PCs? That somehow the PSU can affect a mains socket this way? I think I ought to try a different socket to see if I get the same result? The thing is, I've been using this PC (right now as I type this in fact) for years, so I'm guessing it's a PSU/socket strip thing, but I don't like turning the PC on and off at the mains; I usually leave the PC on for MONTHS at a time.
