PC Test Card LED: The green LED on the PC test card (P/N35G4703) lights when the PCMCIA test is running. If the LED does not go on, check that the card is installed correctly by reseating the card. If it still does not light after reseating, try using another slot for the test. If the LED still does not go on and the test fails, replace the FRU shown in the diagnostic error code. Errors during the POST: If the POST detects an error, a 3-to-8-digit error code is displayed. Memory Errors: If the POST detects a memory error in the first 640 KB of system memory, all the first bank memory is deallocated and the test continues with the second 640 KB of memory. If the total amount of error-free memory becomes less than 2 MB, a 2XX POST error occurs and the system stops. All the remaining memory is used as system memory. When the POST memory test completes, the usable memory size is compared with the configuration data. If a mismatch is detected, a 2XX error code occurs. The user can continue with system operation by pressing Esc and F1 after restart and call for service at a later time. The memory that is deallocated because of the POST process is kept by the hibernation or suspend functions. For this memory to be tested, it must be reconfigured as part of the original memory size. You configure by turning the power off and on. Deallocation support is done only by the POST for memory errors. All irrecoverable memory errors that occur during normal operation cause an interrupt to the operating system. Diagnostics for the SelectaDock Docking System The SelectaDock Docking System Options Diskette helps you troubleshoot the expansion unit, SCSI adapter, and SCSI device problems through a series of menus. Run the diagnostics after you have completed the installation of your SelectaDock Docking System and SCSI devices to verify that these devices work correctly. Do the following: 1. Turn off the computer on the SelectaDock Docking System and external SCSI devices. 2. Insert the Option Diskette (the diskette is shipped with the SelectaDock III) into drive A. 3. Turn on all attached external SCSI devices and the computer on the SelectaDock Docking System. 4. The Logo Screen appears. 5. After a few seconds the Main Menu appears. 634 IBM Mobile Systems HMM
