Removing the Computer Cover

CAUTION:

Before you begin any of the procedures in this section, follow the safety instructions in the

Product Information Guide

CAUTION:

To guard against electrical shock, always unplug your computer from the electrical outlet before

removing the cover.

NOTICE:

To prevent static damage to components inside your computer, discharge static electricity from your

body before you touch any of your computer’s electronic components. You can do so by touching an unpainted

metal surface on the computer.

1 Follow the procedures in "Before You Begin" in your User’s Guide.

NOTICE:

Opening the computer cover while the computer is running could result in a shutdown without warning

and a loss of data in open programs. The computer cooling system cannot function properly while the cover

is removed.

2 If you have installed a security cable, remove it from the security cable slot.

NOTICE:

Ensure that sufficient space exists to support the removed cover—at least 30 cm (1 ft) of desk top space.

NOTICE:

Ensure that you are working on a level, protected surface to avoid scratching either the computer or the

surface on which it is resting.

3 Lay your computer on a flat surface with the cover facing up.
