2-14 Installation

1. Remove the AC adapter from the packaging. Connect the round coaxial

connector supplied with the notebook to the DC IN power receptacle on the

left rear of the notebook as shown in Figure 2-9.

2. Connect the female side of the AC power cord to the AC adapter and connect

the male end to a grounded AC outlet.

2.7 Initial Software Load

After unpacking and setting up the notebook for the first time, you must perform an

initial software load that takes approximately 30 minutes.

Because of the way Windows 95 structures its files, stopping in the middle of the setup

process can cause irreversible file damage.
