C PC-Doctor Diagnostics C.1 Introduction The TM5000 Series Notebooks are shipped with PC-Doctor , a power ful diagnostics tool that can help you deter mine the hardware configuration of a local or rem.
C.3 Keyboar d Navigation The keys shown in Table C-1 can be used to navigate through the PC-Doctor menus: T a ble C-1 PC-Doctor Key Assignments In addition, when you select All Tests from the Diagnostics menu, the Test Selection Menu that appears uses the keys listed in Table C-2: T able C-2 Test Selection Menu Special Keys C.
C.5 PC-Doctor Menus There are several selections available from the menu bar of the PC-Doctor Diagnostics main menu. These include: • ? • Diagnostics • Interactive Tests • Hardware Info • Utility • Quit C.5.1 Online Help (?) To obtain context sensitive help from any menu, press F1 .
• Pass Count - selects how many times tests are repeated. The highest limit is 9999 times. • Test Logging - opens the Log Options menu that lets you define how test results are printed or stored to a file during testing. By default, PC-Doctor produces a test result file at the end of testing if an error was detected.
C.5.4 Hardware Info Menu This menu contains functions that deter mine and report on the setup of the computer . None of these functions per for m diagnostic tests; however any errors are included in the reports. The following functions are available from the Hardware Info menu: • System Configuration - lists main system configuration data.
