Remove the 2.8 mm-long Philips #00 screw located in the M.2 slot.

Do not lose this screw! It must be reused later.

Gently grasp the SSD from where the screw was located.

Pull the SSD to remove it from the M.2 slot. If the SSD does not immediately release, gently wiggle it while pulling.

Once you have removed the old hard drive, pull it out of the plastic heatshield.

This heatshield will be reused with your new hard drive.
