2.2 Troubleshooting Flowchart
If you know the location of the malfunction, turn directly to the appropriate section of this
chapter. If the problem is unspecified, use the flowchart in Figure 2-1 as a guide for
determining which troubleshooting procedures to execute. Before performing any
troubleshooting procedures, verify the following:
Ask the user if a password is registered, if it is, ask him or her to enter the password.
Verify with the customer that Toshiba Windows 7 is installed on the hard disk.
Operating systems that were not preinstalled by Toshiba can cause the computer to
malfunction.
Make sure all optional equipment is removed from the computer.
Make sure the floppy disk drive, if installed, is empty. If no FDD module is installed,
you should use an external FDD to run the diagnostics tests
