Notebook CL57SX - Undetermined Problem
Applicable to: World-Wide
Undetermined Problem:
You are here because the diagnostics tests did not identify the failing FRU.
Check the power supply in use (see Power Systems Checkout). If the power supply is operating correctly, return here and continue with the following procedure.
1. Power-off the computer and remove the battery packs from the computer.
2. Remove or disconnect one of the following devices or adapter (do not isolate FRUs that are known to be good).
a. Non-IBM devices
b. Modem, printer, mouse, or other external device
c. IC DRAM card
d. Hard disk drive (fixed disk drive) or diskette drive
e. Communications cartridge
f. Any adapter and device
3. Power-on the computer and start the system program.
4. Press Ctrl+A to run the system checkout. Do not configure the computer. If diagnostics cannot be loaded from the hard disk, try and load them from the Reference Diskette. Test only those adapters and devices still attached to the computer.
5. If the symptom remains, repeat steps 1 through 3 until you find the failing FRU or until all FRUs have been removed.
6. If all of the FRUs listed have been removed and the problem remains, replace the system board.
