A laptop charger supplies a laptop with energy while it is plugged into an electrical socket. The energy charges the computer's battery while also powering the computer. There are several reasons a laptop charger may need repairs. For example, the charger may become frayed so that the plastic exposes the wiring. If the charger is frayed, it may no longer work to charge the computer and could become a fire hazard. Many laptop charger repairs can be completed without taking the computer to a repair shop.
Examine the laptop charger to look for bent and frayed areas in the cord. Also look at the portion of the charger that plugs into the computer to see if any pins are bent or dirty. Look at the plug that goes into the wall to ensure that the pins are secure and straight.
Clean the portion of the charger that goes into the computer. If the metal components of the charger are dirty or bent, they will not properly connect within the computer, which means that it may not charge correctly. Use a cotton swab and isopropyl alcohol to wipe the surface of the metal and pins.
Move any stuck or bent pins within the portion of the charger that is inserted into the computer. If a pin is stuck or bent, the charge may not transmit to the computer properly. Use your finger to gently move or straighten the pins.
Repair any frayed areas of the cord using a silicone sealer. Protect the area you are working on by laying down painter's tape. Smooth sealer over the frayed area and allow it to dry according to the directions on the product label.
If your laptop charger is not charging your computer, check to make sure that the outlet it is plugged into is functioning correctly. Also check to make sure that nothing is covering or obstructing the charger, since heat can build up within the charger if it is not in a ventilated area, which can keep the charger from functioning.
