If for some reason the eject button fails, you
can open the CD-ROM tray with a paper clip
or similar tool inserted into the eject hole in the
far right side of the front of the tray. Straighten
one side of a paper clip and push it gently into
the hole. The tray will pop out a short distance.

Installing and Removing the Internal
Hard Drive
There is a bay in the bottom of your notebook
which contains the internal hard drive. The
hard drive only needs to be changed if there
is a serious drive failure. You may wish to have
a trained repair person replace a drive for you
and re-install your backed up operating system,
applications and data.

Contact your Support Representative
before making any hard drive replace-
ment whether you or a trained technician
is making the change.
