A house fire ignited when a laptop left on sofa reportedly overheated and caught on fire Monday evening. Firefighters responded to a call by the resident of 603 Lake Ridge around 6: 30 p.m. When they arrived, they could see flames and heavy smoke visible from the outside of the ranch-style house and the living room was ablaze. They were able to put the fire out quickly and left the scene around 7 p.m. The resident had reportedly left the laptop on the living room sofa and accidentally covered it with an overthrow blanket, trapping the heat.
