Turn off the computer.

Take the slide unlocked into position, remove the battery.

Using a Philips #1 screwdriver, unscrew the 5 screws securing the cover.

Push the screwdriver a few millimeters under the cover so that it can be touched with your fingers.

Now lift the cover carefully.

Attention! Disconnect the ventillator cable so that the cover can be completely removed (see next step).

Since the ventillator is mounted under the cover, its power supply cable must first be disconnected so that the cover can then be completely removed.
