Most PC makers have 12V cords available. You have to know your PC model to ensure you get the right one. And the cord is usually specific to that brand/model. A cheaper and more flexible alternative is use an inverter. Electronic stores such as Fry's, Best Buy (bye?), Radio Shack, etc. offer these devices in a number of sizes. For just running a laptop in the TV, get one around 140/150 watts. It plugs into the 12V DC power adapter (cigarette lighter) and produces 110V AC. You simply plug your PC's 110V AC power cord into the receptacle on the inverter. No muss, no fuss. Plus you can use the inverter to charge your cell phone, run a television, or power any other light duty device.
