2.2 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, contact your Toshiba representative for
further action.
❑ 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.
