TP 760E/ED/EL/ELD - Combined System Board & CPU FRU Replacement Information
Applicable to: World-Wide
Abstract :
9546 Combined SYSBRD & CPU FRU Replacement Info
Text :
There are two levels of system board and CPU that could be installed in the following 9546 or 9547 model 760 systems. The new level CPU operates correctly with either level system board, but the early level CPU will only operate correctly with the early level system board.
When replacing a system board FRU, identified by the bar code in FIG 1 or by the level of module in Fig 2 and 3, a new CPU should be ordered. This is because the early level system board will most likely have an early CPU that will not match the newer level system board from FRU stock.
NOTE: The CPU level can not be determined until it is removed from the system.
Detail :
ThinkPad 760 Systems affected:
Model EL/ELD U4H,U4F,U6F,U6G,U3F,U4R,U4S,U6R
Model E/ED U3A,U3B,U4A,U4B,U3L
SYSTEM BOARD IDENTIFICATION METHOD 1. (FIG 1)
When ordering a replacement system board for one of the above 760 models check the bar code of the failing board. If the bar code contains 1MH, 1MP or 1MR, the system board is at the early level and the CPU level should be checked before it is swapped from the old system board to the new level system board. If the CPU that was ordered is not used return it. (Check FIG 4 for CPU FRU numbers.)
The bar code is located below the option in the ULTRA BAY. Lift the keyboard and remove the option to see the Bar code. The X in the figure represents any letter or number and is not relevant.

SYSTEM BOARD IDENTIFICATION METHOD 2. (FIG 2)
Alternative method to identify older level system boards if the bar code is damaged: This can only be done after the system board is removed from the computer.

Note :
If the sysbrd module identified in Fig 2 and 3 has SU036 or SU037 on it the system board is at the older level. If the CPU that was ordered is not used return it.
