NO, a laptop power supply is designed with a known value of intended power consumption expected. if you connect a small portable television to the DC supply, it will overload the supply and destroy it. there is very little wiggle room in supply performance . a supply is built to supply the laptop with a specific current while allowing enough to charge the battery. I don't advise connecting it but if you do, you want to make sure the battery is charged or removed. and the television draws less than 1 amp of current. but like I said, not a good idea. power supplies are cheap, get one for the television.

On a desk top, it connects power from the outlet on the wall to the power supply in the computer. On a laptop. It converts the mains AC power at high voltage to a low voltage DC.

On a desk top the power supply is inside the cabinet. On a laptop it is separate. This saves weight and space when using the laptop totally portable and running on battery
