The diskette fixes are located on the PC Company Bulletin Board Service (BBS). The direct phone line for modem connection is 919-557-0001 or tieline 255-0001. Advise customers to contact the PC Company HelpCenter at 800-772-2227 if they need assistance in obtaining or installing any diskette fixes. Customers in Canada should call IBM HelpPC at 800-565-3344 for assistance or down-load information. The Canadian BBS phone numbers are: Montreal Toronto Vancouver Winnipeg 514-938-3022 905-316-4255 604-664-6464 204-934-2735 FRU Replacement Strategy Ensure that all diskette fixes are installed prior to replacing any FRUs. And, use the following strategy to prevent unnecessary FRU replacement and service expense: If you are instructed to replace a FRU and that does not correct the problem, reinstall the original FRU before you continue. Some computers have both a processor board and a system board. If you are instructed to replace either the processor board or the system board, and the first board that you replaced does not correct the problem, reinstall the original board, then replace the other (processor or system) board. If an adapter or device consists of more than one FRU, an error code may be caused by any of the FRUs. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms. Attention A customized setup configuration (other than default settings) may exist on the computer you are servicing. Running Automatic Configuration may alter those settings. Note the current configuration settings (using the View Configuration option) and verify that the settings are in place when service is complete. The advanced diagnostic tests are intended to test only IBM products. Non-IBM products or modified options can give false errors and invalid responses. IBM ThinkPad 380XD, 385XD (2635) 3 Hard Disk Drive Replacement Strategy: Always try to run a low-level format before replacing a hard disk drive. Attention The drive startup sequence in the computer you are servicing might have been changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive. How to Use Error Messages Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed, begin the diagnosis with the first error code. The cause of the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing. How to Read POST Error Messages POST error messages are displayed on the screen as three, four, five, or eight digits. The error messages that can be displayed as shorter POST messages are highlighted in this index. Some digits will represent different information for SCSI errors versus non-SCSI errors. The following example shows which digits display the shorter POST error messages and also defines the SCSI information in an eight-digit error message. Shorter POST Messages Reserved Size (SCSI) Slot Number (SCSI) Device Code Logical Unit Number (SCSI) ID (SCSI) All SCSI devices are set to a different SCSI ID. Duplicate SCSI ID settings can generate a false error message. Use the SCSI ID to determine whether the error message is coming from an internal or an external device. 4 IBM ThinkPad 380XD, 385XD Safety Notices (Multi-lingual Translations) In this manual, safety notices appear in English with a page number reference to the appropriate multi-lingual, translated safety notice found in this section. The following safety notices are provided in English, French, German, Italian, and Spanish languages. Safety Notice 1 Before the computer is powered-on after FRU replacement, make sure all screws, springs, or other small parts are in place and are not left loose inside the computer. Verify this by shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause electrical shorts. Avant de remettre l'ordinateur sous tension après remplacement d'une unité en clientèle, vérifiez que tous les ressorts, vis et autres pièces sont bien en place et bien fixées. Pour ce faire, s ...
