Most Toshiba laptop models use a 19V DC power supply that connects into the laptop DC jack. Some laptop owners find that the original charger that came from Toshiba has to be “wiggled” or moved from side to side before their laptop would turn on. In this scenario, the problem will be either the AC adapter, the internal DC jack located inside the laptop or both. If replacing the charger does not fix the problem, the cause is most likely due to a faulty connection between the DC jack and the laptop mother board.
Beware of AC Power Cord or DC Jack Over Heating or Signs of Melting
Pay attention to the laptop operating temperature and power cord during normal use to avoid potential damage to the laptop, mother board or worst. In addition, make sure that any replacement AC power source provides the recommended voltage specified for your machine.Example of Damaged DC Jack Base Assembly inside Toshiba Satellite A205 Laptop
Toshiba Satellite Pro L300, L350, L300, L305D, L355D, P305, P305D, and other Toshiba laptops have a common DC jack problem.
Intermittent power problems are usually the result of solder breaks or broken center pin located inside the DC jack itself. If the DC Jack is bad, this repair can cost between $65-$150, depending on the model laptop and the repair shop. Some computer repair shops insist on replacing the entire motherboard, which can cost up to $500.00. Just make sure that you understand the problem before pouring money into changing parts that may or may not be the root of the problem.
