But don't worry, you can follow the following instruction:

Check the HP 375118-001 AC Adapter by looking for screw-holes and running a firm fingertip over any stickers to see if they conceal screws. Most laptop ac adaptersare glued together, but the occasional unscrewable model exists. If you do remove screws, but the HP AC adapter is still stuck together, there's probably glue in there.

Separate the seam by sliding the thin blade into it along one of the long sides. Slip the small-tipped standard screwdriver in to use as a prybar. Continue around the seam, using the blade to split new sections and the thicker screwdriver to hold them apart. Work patiently and be very careful not to force the blade or screwdriver too far in. Pull the outer HP 375118-001 AC Adapter casing apart and set it aside. Locate the section on the internal circuit board where the cable leading to the laptop is soldered in. Tin the soldering iron tip, then heat the solder holding the wires in place and remove it using your preferred method. Once the wires are loose, examine them for any breaks or odd sections, trim and re-strip as necessary and tin the tips of the wires before re-soldering them to the board.
