4.1. Preparation

3. Close the laptop lid and place the laptop upside down on a clean, soft, and static-free surface.
4. If your laptop has a removable battery, unlock and remove it.

4.2. Removing the Old Bottom Base Cover

1. Locate all screws securing the bottom base cover. These are typically visible on the underside of the laptop. Some screws may be hidden under rubber feet or stickers.
2. Using a Phillips head screwdriver, carefully remove all screws. Keep track of their locations, as they may vary in size.
3. Once all screws are removed, gently pry around the edges of the bottom cover using a plastic prying tool. There may be plastic clips holding the cover in place. Work slowly and carefully to avoid breaking these clips.

  Double-check the laptop model number against the compatibility list. Ensure all internal components are correctly seated and not obstructing the cover. Verify that no screws or small parts are trapped between the cover and the chassis.
• Screws Do Not Align:

  Ensure the cover is perfectly aligned with the chassis. Sometimes, a slight adjustment or gentle pressure is needed to align all screw holes. Do not force screws.
