TP 700,720 - New FRUS for Upgrade Options
Applicable to: World-Wide
Service Information:
The 9552 has two options that require FRU upgrades when they are installed. The options are the processor upgrade from 25MHz to 50MHz and the 240Mb fixed disk upgrade. When either of these options are installed a plugable module is replaced on the system board along with a new system board FRU number which is placed over the old FRU number.
Note:
The Bios Rom part numbers listed in the matrix below can be used to identify the system board, if the sysbrd FRU label was not installed during an upgrade. These can not be ordered as FRUs.
The Bios Rom module is located on the system board in a 3/4" by 5/8" plugable socket. If the system board fails because of the upgrade installation a system board FRU must be ordered.
The IBM ThinkPad 700/700C/720/720C Ref/Diagnostic Diskette must be at version 1.20 or later to support the 240Mb disk upgrade. The 486 processor upgrade option for the 700 and 700C 9552 systems upgrades the system speed from 25MHz to 50MHz. The option allows the customer to choose battery saver, 25MHz or 50MHz speeds. If the option is installed the new power management screen will look like this:
"AUTO(LONG BATTERY LIFE)"
|
|
"MAX(HIGH PERFORMANCE)"
|
|
"DOUBLE(50MHz)"
Note:
Only systems with the upgrade will have "Double (50MHz)"
The following chart documents the correct system board and processor FRU based on model and options.
