For all the function and portability laptops provide, there are also some drawbacks. The biggest problem with laptops is with dc jack life. To get constant dc jack , the laptop has to be plugged into a wall outlet. The wall plug then connects to the DC jack in the back of the laptop. The DC jack is no more than a little piece of metal that conducts the electricity for the computer. These DC jacks are known to be fragile and break off easily. If this happens, you can open the laptop and replace the DC jack yourself
1.Remove the internal battery pack from your laptop. Flip the laptop over and locate the release button for the battery pack. Hold the button in to slide the battery pack free. It is important that you remove the internal battery pack as well as unplug the power cord from the wall outlet to prevent risk of shock while working inside the laptop.
2 .Unscrew all of the screws on the underside of your laptop. The number of screws will depend on the model of computer. There should be one at each corner and then one or two screws that hold the hard drive cover in place. Once the screws are removed, take out your computer's hard drive. Newer-model computers will have a hard drive that slides out of the side of the computer.
3 .Locate the two screws at the back of the computer that hold the laptop screen's hinges in place. Once these two screws are removed, gently pull up on the screen until you clear the silver pegs from the holes in the laptop's body. Two wires lead from the screen into the computer, so ensure you do not pull so hard that you disconnect them. Carefully set the laptop screen aside so it does not get damaged while you work inside the computer.
4 .Separate the two halves of the laptop's body to expose the computer's internal components. Flip the keyboard on its face, making sure not to disconnect the keyboard's connector. Underneath the keyboard will be a metal plate that covers the computer's motherboard. Unscrew the screws that hold this plate in place and set it aside.
5 .Locate the DC jack for the laptop. Most all laptop's DC jack outlets are located at the back left corner of the computer. Using your tweezers, remove the old DC jack. Identify the slot in the motherboard that the old DC jack came out of. If the DC jack was loose before you removed it, there will be a small slot at the base of the opening in the back of the computer that the DC jack pops into. Using the tweezers again, slide the new DC jack into this slot until you hear a clicking sound. To hold it in place you can solder the new jack to the motherboard, or simply superglue it in place. Don't use too much superglue or you will risk losing the ability for the jack to conduct electricity.
