Troubleshooting Flowchart

Use the flowchart in Figure 2-1 as a guide for determining which troubleshooting procedures
to execute. Before going through the flowchart steps, verify the following:
Ask the user if a password is registered, and if it is, ask him or her to enter the pass-
word. If the user has forgotten the password, refer to Appendix H for procedures on
how to delete it.
Verify with the customer that Toshiba MS-DOS is installed on the hard disk. Non-
Toshiba operating systems can cause the computer to malfunction.
Make sure all optional equipment is disconnected from the computer.
After removing all optional devices, if the T6600C is found to be operating properly,
then an optional device or a T6600C interface is causing the problem.
Check the following items:
For a memory card, PCMCIA card, turbo cache module, and connected I/O port
devices, check the T6600C with the optional device or with a wraparound board for
the I/O port using the test program.
If the T6600C works with no errors, the optional device is malfunctioning. If the
T6600C does not work or there is an error, the system board is malfunctioning.
For expansion slot cards, check the T6600C with a wraparound board for an expan-
sion slot.
If the T6600C works with no errors, the expansion card is malfunctioning. If the
T6600C does not work or there is an error, the back panel board or system board is
malfunctioning.
Make sure the floppy disk drive is empty.
