Non-Skid Feet Replacement Process

Preliminary Requirements

Important

Be sure to follow all special (bolded) notes of caution within each process section.

Required Tools and Components

  • Tools:
    • Plastic tweezers / spudger
    • Isopropyl Alcohol Dispenser Bottle (use only 70% IPA)
    • Cleaning swabs
  • Components:
    • Feet (Refer to Illustrated Service Parts List)
    • Front Foot
    • Rear Foot

Prerequisite Steps:

  • Power off device – Ensure device is powered off and disconnected from a power supply.
  • General Safety – Check to make sure that general guidelines and ESD compliance steps are followed prior to opening the device.
  • Position device – To prevent scratches, flip device over onto a clean surface free of debris with the device bottom facing up for access to the feet for removal.

Procedure – Removal (Non-Skid Feet)

  1. Remove Feet – Use a plastic tool to pry up the foot from one end and then peel to remove. Repeat for the other foot.

    Important

    The front and back feet aren't the same. There's one locating post on the rear foot near the left hinge and two locating posts for the front foot below the trackpad – refer to illustration for details.

  2. Feet removal technique – Use plastic tweezers / spudger to lift one edge of each foot. Grasp the loose end and pull the foot from the D-Bucket. Ensure all adhesive tape remnants and glue residue are removed. Clean the D-Bucket foot recesses with 70% Isopropyl Alcohol.

    Important

    Once removed, the Feet will be stretched out of shape and must be replaced with new ones.

Procedure – Installation (Non-Skid Feet)

Important

Any further repairs that are required on the device should be carried out prior to feet installation. Don't reuse feet previously removed from a device.

  1. Prepare new front foot and press into place – To install the front foot, remove protective sheet to expose adhesive on foot. Align the two locating posts for the front foot. Press the foot in firmly. Then slide your hand up and down the length of the foot to ensure that it's secured in place.

  2. Inspect for anomalies – Examine foot to ensure no cosmetic damage or gaps between the foot and the D-Bucket foot recesses exist.

  3. Prepare new back foot and press into place – To install the back foot, remove protective sheet to expose adhesive on foot. Align the one locating post for the back foot. Press the foot in firmly. Then slide your hand up and down the length of the foot to ensure that it's secured in place.

  4. Inspect for anomalies – Inspect foot to ensure no cosmetic damage or gaps between the foot and the D-Bucket foot recesses exist.

    Important

    Before transporting the device, we recommend letting it sit feet-down on a tabletop for at least 12 hours. If this isn’t possible, it’s recommended to avoid placing the device in a backpack, purse, other types of carriers, until at least 12 hours after installing new feet.
