HP recently recalled power cords for certain HP/Compaq laptops & Mini-Laptops. The cords can overheat and potentially start a fire.
Here is how to check to see if your cord is one of the ones recalled. Find where your cord plugs into the wall and follow it to the brick. The part of the cord that comes from the wall plugs into the brick. The picture on the left shows part of the cord that plugs into the brick. Note the LS-15 that is stamped there. If your cord has LS-15 stamped on it just like the one in the picture, then you have one of the recalled power cords.
If you do have one of the recalled power cords, you can get it replaced by HP for free. All you have to do is click on this link.
Don’t put off doing this. While you are waiting for your replacement power cord, you can continue to use the old one. Just make sure that the cord is not touching anything that is flammable.
