Abstract:
ECA002, 9545 MOD 755CE/CSE/CD Trap, Hand, or no power
Purpose :
When replacing any FRU within the logic assembly inspect the DC/DC card FRU P/N85G1500. Replace it if it matches the PHYSICAL CHECK. A small number of DC/DC adapter cards of this level could cause solid hangs, Trap 2, D, E or no power conditions.
This ECA is to be implemented World Wide!
The repair policy for this ECA is "Fix On Contact".

Physical Check :
1. Remove the main battery. A label on the base cover under the battery stating "EC F00944 Applied" indicates this ECA is already installed. No further inspection or action is required.
2. If the label described above is not under the battery, examine the DC/DC card, FRU P/N 85G1500. If it has a red capacitor with date code of 4HC in position 41, or a red capacitor with a date code of 4JC or 4KC in position 50, the DC/DC card must be replaced.
See the Detail section for position locations.
NOTE: DC/DC cards with purple capacitors in position 41 or 50 are at EC F00944 and do not require this ECA.
Detail :
The 9545 755 CE, CSE, and CD models in the FEATURES SECTION without an EC label F00944 installed should have the DC/DC Adapter FRU P/N 85G1500 checked when any FRU in the system's Logic assembly is being serviced.
Use the DC/DC Adapter card diagram in Figure 1 to determine the position of the affected capacitors. If they are present, replace the card. All DC/DC Adapter card FRU stock of P/N 85G1500 contains the correct level capacitors.
