• Advance the pick, tracing the lower-right corner of the display and moving towards the power button, noting the resistance indicating a retaining clip's presence.This clip secures the display assembly.Reorient the pick, positioning its flat surface beneath the display's surface.
• This positioning facilitates separation.Carefully maintain the pick's orientation during the separation process.Avoid exceeding the specified depth to prevent component damage.

Utilize a prying tool to widen the separation between the display assembly and the device's chassis.Continue expanding this gap until the retaining clip on the right side disengages.The right clip secures the screen to the frame.Position a second prying tool adjacent to the initial one to maintain the separation.
This dual-tool approach facilitates controlled release of the screen.

Move the initial prying tool toward the lower-right edge of the display panel.The lower-right portion of the screen's surface should be the target for the first pick's movement.Position the second prying tool against the upper-right corner of the screen's surface.The adhesive bond securing the display is released by sliding the second pick to the upper-right corner.
Maintain the position of both picks within the separation gap to inhibit the adhesive from re-bonding.Keeping the tools in place prevents the adhesive from reattaching to the screen.The adhesive layer's integrity is disrupted by the sliding motion of the tools.The initial prying tool should be moved to the lower-right corner.
The second prying tool is moved to the upper-right corner.

To facilitate separation, apply heat to the screen's upper boundary until its surface reaches a temperature that is comfortably felt by hand.

• To prevent damage, limit the insertion depth of your tool to a maximum of 3 millimeters near the upper boundary.The upper edge should be carefully accessed with a prying tool to avoid component stress.Moving the tool along the top right corner and the upper edge will disengage the two retaining clips.
• This movement also separates the adhesive that holds the component in place.

Applying warmth to the screen's left border, until a tactile sensation of heat is perceived, is necessary.

• To prevent damage to the two cables linking the display to the device's mainboard, ensure the opening of your prying tool does not exceed a depth of 2 millimeters along the left side.Employ a rotational motion with your prying tool, focusing on the upper-left corner of the screen's perimeter.Advance your prying tool along the left edge, moving downwards towards the screen's lower-left corner, to release the adhesive bond.
• The adhesive securing the screen will be released as you slide the tool along the edge.
• Care must be taken to avoid contact with the screen's connection cables during separation, as damage could occur.

• Carefully pivot the display assembly to the left side of the device.
• Should resistance be encountered during screen separation, re-examine the device's edges to identify any remaining adhesive or secured clips.
• To prevent cable stress, prop the display open using a supporting structure like a box.

• Carefully monitor the location of every screw during the repair process, ensuring each is reinstalled in its original position.
• Employ a specialized tool, specifically a tri-point Y000 driver, for the subsequent steps.The logic board cover is fastened with screws that require a tri-point Y000 driver for removal.A single screw, measuring 2.1 millimeters in length, is used to secure the cover.
  
  • Five screws, each with a length of 1.5 millimeters, also contribute to the cover's retention.
