- A small Phillips screwdriver (PH0 or PH1 size)
- A plastic or metal pry tool
- Tweezers (optional, for handling small screws or connectors)
- An X-Acto knife or thin blade (for removing screw covers and adhesive tape)
Also, make sure you have a clean, static-free workspace to avoid damaging any components.
- Shut down your laptop completely.
- Disconnect the AC power adapter.
- Flip the laptop over and locate the battery release latches.
- Slide the latches to unlock and carefully remove the battery to ensure no power is running through the device during the repair.
- On the front of the screen, look for small plastic screw covers usually located at the bottom corners of the bezel.
- Use the X-Acto knife or a thin blade to gently pry off these covers.
- Using the Phillips screwdriver, remove the screws hidden beneath these covers.
- Carefully pry the bezel away from the screen assembly by inserting your fingers or a plastic pry tool along the edges and gently snapping it off. Work your way around the screen to release all clips without breaking them.
- Once the bezel is removed, you will see the LCD screen secured to metal mounting brackets on each side.
- Locate and remove the screws holding the screen to these brackets. Typically, there are two or three screws on each side.

- After disconnecting the cable and removing all screws, carefully lift the screen away from the laptop.
- Place it aside safely.
- Take your replacement screen and remove any protective films.
- Connect the video cable to the new screen, ensuring it clicks into place firmly and evenly.
- Secure the cable with adhesive tape as it was originally.
- Align the new screen with the mounting brackets and reinsert the screws on both sides.
- Tighten the screws securely but avoid overtightening.
- Snap the bezel back onto the screen assembly by aligning the clips and pressing gently around the edges.
- Replace the screws at the bottom corners and cover them with the plastic screw covers.
- Flip the laptop back over and reinstall the battery.
- Connect the AC adapter and power on the laptop.
- Verify that the new LCD screen displays correctly without flickering or dead pixels.

- Always disconnect power sources before starting the replacement to avoid electrical damage or personal injury.
- Keep track of all screws and parts removed; organizing them in order helps during reassembly.
- Be gentle when prying off the bezel to avoid breaking plastic clips.
- Avoid touching the LCD screen surface directly to prevent fingerprints or damage.
- If the screen does not turn on after replacement, double-check the video cable connection and screw tightness.
