Before you begin to remove the bottom cover, shut down the computer. Disconnect all external devices and unplug the AC adapter. Flip the laptop upside down.
Use a Phillips #0 screwdriver to remove five screws from the bottom cover:
Two 5.6 mm screws
Each of these screws are beneath the two rubber feet on the rear side of the laptop (near the display hinges). You do not have to completely remove the rubber feet to remove the screws; simply peel the top of the feet to reveal the screws.
Three 5.8 mm screws
Throughout this repair, keep track of each screw size and location to avoid damaging your device.
