Restoring the Partition
If a computer or hard disk problem prevents system setup
or diagnostic programs from being loaded from the
protected partition, load and run the programs from the
Reference Diskette. If no errors are found, restore the
programs to the protected partition on the hard disk using
the following procedure.
1. Start the computer with the customer's backup copy
of the Reference Diskette installed.
2. Select the Backup/Restore system programs from
the Main Menu.
3. Select the Restore the system partition to load the
system setup and utility programs, and the customer
and advanced diagnostics programs onto the system
partition of the hard disk.
If this does not correct the problem, use the backup copy
of the Reference Diskette to format the hard disk and then
restore the programs to the protected partition. If the
problem remains, return to the
I
998XXXX,
I
9990303 error
code (on page 126 in the Symptom-to-FRU index).
Note: After the programs have been restored, the
Diskette and F1 prompts appear, unless an
operating system is present.
CL57 LCD FRU Replacement Notice
If missing or discolored dots appear on the LCD, carefully
read the following note to determine whether you should
replace the LCD.
Important
The LCD for the Model CL57 contains over 921 000
thin film transistors (TFTs). A small number of
missing, discolored or lighted dots (on all the time) is
characteristic of TFT LCD technology, but excessive
pixel problems can cause viewing concerns. The LCD
should be replaced if the number of dots satisfies
either of the following conditions:
The number of missing or discolored dots in any
colored back ground, except black, is 14 or more.
The number of lighted dots in a black background
is 7 or more.
