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, do 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, connect the printer port wraparound
board (F31PRT), then turn the POWER switch on. The computer will override the
password function by erasing the current password.
❑
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.
❑
Make sure the floppy disk drive is empty.
