Use a pair of tweezers to peel up the black pull tab on one of the stretch-release adhesive strips until you can grip it with your fingers.

Pull the strip out from under the battery at a shallow angle. Go very slow and use steady force, giving the strip plenty of time to stretch and unstick itself from under the battery tray.

You may have to re-grip the adhesive closer to the laptop and continue pulling multiple times—the adhesive will stretch a lot.

Pull the adhesive strip until it’s completely freed from underneath the battery tray.

Repeat for the seven remaining adhesive strips.
