Our 11 year old refrigerator stopped getting cold enough (42 to 48 degrees). It's done this before and we've replaced parts. This time I decided enough and replaced the unit. Now this new LG refrigerator is doing the same thing. I've had a tech come out and they replaced the board with all the pertinent parts and it still isn't getting colder. But I've plugged in our old unit in the garage, where it is cooler, and now it's at the correct temp. Is it possible that it can be something to do with the electrical outlet? Wouldn't the service guy have had something to test that?

There's a downed cable/wire in my building's backyard. It is similar to this previous question, but there is no serial number on the wire so I can't confirm what it belongs to. Also, one side is attached to our building and the other end is attached to...nothing. What do I do with it? [more inside]

Is there any point to using the 'storage' part of storage heaters if you don't have an offpeak tariff?
I've just moved into a new place that only has storage heaters for heat. However, the tariff on the electricity does not have an offpeak component. Given this, I was wondering if there's any point in using the storage aspect of it (if its more efficient, for example) than just using the 'boost' function that gives you heat instantaneously.

What just went ka-bing on my stove? I was just cooking pancakes on the stove. The oven was also on at 300 degrees, to keep the pancakes warm as they came off the griddle. The overhead bonnet light was on as well. Suddenly there was a strange flash. It happened in such a fraction of a second that I cannot tell you where it was from. It was like a tiny red sparking mini-explosion -- somewhere! I turned off the stove -- and could NOT turn off the light on the bonnet! [more inside]

My laptop power cord's ground prong (the third prong) broke off, and it stopped working in most wall plugs. I ordered a new one and when it came, it didn't have a third prong, but it works fine.

After a move, our computer (an older aOpen desktop) can't sleep through the night. It's fine if we leave it powered on, but if we put it to sleep, it seems to lose power sometime in the night and does not wake up properly in the morning. Will a cheap UPS (this one, for example) solve the problem? Any other ideas?
Four days ago there was a storm. Standing ankle deep in water which had flooded up to my front door step, I stuck my metal key into my apparently 100% metal door and ended up sort of electrocuting myself, feeling a tingle and shock going up my arm. Since then I've had this weird tingling sensation in my right hand and arm up to my elbow... just now I tried to hold up a can of soda my fingers and hand tremble. Now what? [more inside]

Music-playlist-filter. An attempt at the world 24 hour record for producing electricity by cycling needs a soundtrack. Can you suggest some appropriate music? I'm thinking cycling, electricity, endurance would all be good themes, but any other related themes would be welcomed too.
