You are describing a classic wiring short circuit. Either the cables of your power supply or the jack on the laptop itself are damaged and need to be repaired or replaced as soon as possible to avoid permanent damage. There is no logical reason it would work only in certain outlets, that is probably just coincidental to the way you have the cable running while plugged in to each outlet.

Your power supply has two cables, the side leading to the AC outlet is removeable and easily replaced but the side leading to the laptop's jack is not. Start with the AC plug. Leaving everything from the 'brick' to the laptop in a stable position, gently flex the AC cable until you see evidence of the short (usually a break in the wire, possibly chewed by the dog or snagged on the edge of a desk). If so, replace the AC wire. If not, try the same with the laptop side of the brick. If so you usually should replace the entire power supply unless you are real handy with a soldering iron.

If moving the position of the two power supply cables doesn't identify the short, you must suspect the laptop's jack of being loose. This is worst of all because the laptop motherboard has to be removed to gain access to resolder the jack, a professional job that will run probably $100.
