LCD FRU Replacement Notice
If missing or discolored dots appear on the LCD, carefully
read the following note to determine whether or not
you should replace the LCD.
The LCD for the Model 700C and 720C contains over 921000 thin
film transistors (TFTs). A small number of missing, discolored or lighted
dots (on all the time) is characteristic of TFT LCD technology.
Excessive pixel problems can cause viewing concerns.
The LCD should
be replaced if the number of missing, discolored, or lighted dots in any
background is 21 or more.
Hinges on the color LCD are part of the FRU and are returned with the FRU.
700, 720 Mono LCD FRU Replacement
Hinges are NOT part of the Model 700 or 720 mono LCD FRU (do not return
them with the FRU). When replacing the Model 700 or 720 mono LCD, remove the
right and left
hinge bracket supports and install them on the new LCD. Return only the
main FRU. The left and right hinge bracket supports are included in the Mono
Panel Cover Group Kit.
High-Speed Modem Noise Problems
A small number of high speed modems might produce a noise when the system is
powered-on. To solve this problem,
copy PS2.EXE from the Reference Diskette to the root directory using the
UINSTALL program. Then, add the following lines to the AUTOEXEC.BAT file.
PS2 SET MODEM OFF
PS2 SET MODEM ON
If this does not solve the problem, replace the modem.
