This step only applies to the reassembly process. The hinges use damping grease to control how quickly the lid opens. If the hinges spin too freely, or if you accidentally wiped off a lot of grease, you may need to apply new damping grease.

Pull the inner portion of the hinge out of the housing.

Use a spudger or popsicle stick to apply a small amount of high viscosity damping grease to the inner portion of the hinge.

Push the inner portion of the hinge back into the housing.

Scrape off excess grease with a spudger or popsicle stick. Use paper towels and isopropyl alcohol to clean grease off of any other surfaces. If you're cleaning grease from electronic components, make sure you use high concentration (greater than 90%) alcohol.
