Record number: H134978 Device: D/T9546 Model: M Hit count: UHC00000 Success count: USC0000 Publication code: PC40 Tip key: Date created: O96/10/17 Date last altered: A96/11/07 Owning B.U.: USA Abstract: 9545/46/47 & 2625 POST 8603 OR 8611 AND KYBD RESETS. SYMPTOM: Full size and space saver external Trackpoint keyboards can cause an 8603 or 8611 POST error during boot or cause a keyboard reset to occur during normal operation. The Reset will cause the NUM, CAPS, and Scroll Lock LEDs to flash on then off. The intermittent condition can occur on all models of the 9546 9547 760 model systems, 9545 755 systems and on the 2625 365X model systems. PROBLEM ISOLATION AIDS: Ensure the software work around or the hardware cable kit listed in the fix section of this tip is installed before replacing any other FRU parts. FIX: A partial work around is now available on the PCCO BBS. The file for DOS / Windows / Windows 95 is called YPTF$034.EXE; the OS/2 file is called YPTF$035.EXE. The work around corrects the keyboard reset, but will not correct the intermittent POST error. NOTE: The software work around is not effective when hot or warm docking is used. Setting the internal trackpoint to OFF with ThinkPad features will prevent either error condition, but the internal trackpoint will not operate. A hardware fix will be available by the end of November. It will consist of a TrackPoint keyboard adapter cable. The kit is FRU P/N83H6472. This kit is a Customer Replaceable Unit (CRU) and can now be obtained by your customer at no charge when they call the IBM PCCO Help Center at 1-800-PS2-2227 (1-800-772-2227). ThinkPad 760 and 365X Systems: Plug the Adapter Cable, FRU P/N83H6472, into the keyboard cable connector with the mouse symbol. Plug the other end of the Adapter Cable into the Docking station or Port Replicator mouse port connector (Figure 1). If a ThinkPad is being used stand-alone, plug the other end of the Adapter Cable into the keyboard / mouse connector cable's mouse port in (Figure 2).
