I have a paper shredder but it's near the computer in the office. As far as the other issues mentioned on this board like Retired Fire Chief stated, have the electrical looked at. When I worked in a salon the power would dim and never go completely off. My dear dad told me a long time ago if that happens cut the power of and have it checked. I walked out side, hit the main switch, smelled smoke, looked up and saw the transformer on top of the electric pole was on fire. Called the fire dept. Was told that since the wiring was so old it wouldn't have taken much for the building to go up in flames.
