Toshiba Satellite L305-S5865 Power Supply Repair
Issues with the power supply are commonly seen in Toshiba Satellite laptops and model L305-S5865 is no exception. The bulk of these problems stem from the power jacks. They typically tend to lose contact between the positive pin and the motherboard. Your laptop should never run on battery power when the power adapter is plugged in correctly. To address this specific issue you will have to disassemble your laptop. It is recommended that you only perform this task if you have a strong working knowledge of laptop repair and if you know use a soldering iron safely.
Instructions
1. Disassemble your laptop. See the link in the "Resources" section below for detailed instructions if you don't already know do this. Remove the plastic supports from inside the base assembly using a knife, leaving the side where the new jack will be mounted completely flat.
2. Remove the plastic wall that goes around the outside of the mounting hole, using the knife. Open the hole outward by cutting it with the knife to expand it until the new jack can fit through.
3. Bend one end of the negative lead on the jack up toward the remaining end to shorten it so that you can reinstall the laptop cover back on the base without hitting the speaker box. Apply solder to cover both ends of the negative lead.
4. Pull the old power jack out and use the knife to trim the wires that come out of the jack close to the jack box. Strip the wire with the knife then twist the wires together with your fingers, apply solder where they join. Connect the positive green or red wire into the positive lead in the middle of the new jack. Connect the negative black wire into the negative lead that you shortened in the previous step.
5. Insert the new power jack in the base and solder the wires to the appropriate leads on the jack. Allot enough room to fit the cover and right speaker into place later. Cover the negative and positive leads with electrical tape.Tighten and secure the nut on the power jack by twisting it clockwise with your fingers as far you can go.
6. Determine which plastic reinforcement walls are going to be in the way of the power jack once the cover is in place. Remove the applicable walls with the knife to prevent the creation of a gap between the cover and the base. Assemble your laptop by reversing the dis-assembly instructions found in the "Resources" section below.
