Physical check:
The system must contain system board FRU P/N12J0405, P/N05K3456, or P/N10L1559 to qualify for this ECA application.
The system board FRU part number can be seen by opening the DIMM door on the bottom of the system unit. To do this turn the ThinkPad over (front facing you), open the DIMM door. The system board FRU part number will be located on the system board at the upper right of the DIMM door opening. FRU P/N12J0405, P/N05K3456 or P/N10L1559 will be painted (silk screened) in this area.
NOTE:
The new level replacement system board will have FRU P/N10L1574 written on a label in same area as the old part number.
NOTE:
A small number of early board fixes did not receive the FRU label containing FRU P/N10L1574. Because of this, along with the FRU P/N10L1574 label, the following will also indicate that a correct level card is installed in the system.
1. Label with FRU P/N10L1574 or newer substitution.
2. Discrete wire fix (shown below) and the old silk screen number.
Prerequisites: NONE
Companion: NONE
Concurrent: NONE
Detail:
The 770 system may hang during any phase of POST, if system board FRU P/N12J0405, P/N05K3456, or P/N10L1559 contain SDRAM memory DIMMs. To correct this condition any of the above FRU part numbers should be replaced by an IBM authorized servicer with system board FRU P/N10L1574 (or later Substitute) during any system repair action or contact.
Note: SDRAM Memory installation or system hang failures are not required to qualify for this ECA.
Notes: This ECA will expire on April 1, 2000. Order all FRU parts locally, and record Time and Material to service code 33, ECA 002, and OTHER OFFICE 990.
This ECA is Non-Billable as long as it is Active.
