Turning Off the Hard Disk
To avoid drive access problems, it is best to leave the hard
disk switch on at all times. However, if you are using the
computer without the AC adapter, you may want to turn the
hard disk off when you are not using it to conserve the charge
of the computer's battery. The hard disk drive uses more of the
battery's charge than a diskette drive.
You can turn off the hard disk either before you turn on
the computer or after:
If you do not plan to use the hard disk at all, turn it off
l
before you turn on the computer.
If you need to load MS-DOS or an application program or
l
access files on the hard disk, leave the hard disk switch on
when you turn on the computer and turn it off later as
described below.
Turning off the hard disk first
If you will not be using the hard disk at all, turn off the
switch before turning on the computer. When you turn on the
computer, the screen displays this error message:
1701-C
Press
to continue. Insert the MS-DOS diskette in drive
F1
A and load the operating system from that drive. Then you
can use the computer just as you would if it had no hard disk
drive. Remember, if you do this, you cannot access the hard
disk even if you turn it on.
Turning off the hard disk later
If you want to use the hard disk at any time during your
session, turn on the computer with the hard disk switch turned
on. You do not need to use the hard disk all the time, and
you can turn it off after the operating system has loaded or
after you have loaded an application program from drive C.
However, there are a few things you need to know about using
the hard disk this way.
