Diagnostics using PC-Doctor for DOS The ThinkPad computer has a test program called PC-Doctor for DOS (hereafter called PC-Doctor.) You can detect errors by running the diagnostics test included in PC-Doctor. This section is an overview of the procedure. For details that depend on model-unique functions, refer to “ThinkPad X300” on page 47. For some possible configurations of the computer, PC-Doctor might not run correctly. To avoid this problem, you need to initialize the computer setup by use of the BIOS Setup Utility before you run PC-Doctor. To enter BIOS Setup Utility, do as follows: 1. Turn on the computer. 2. When the ThinkPad logo comes up, immediately press F1 to enter the BIOS Setup Utility. Note: If a supervisor password has been set by the customer, BIOS Setup Utility menu appears after the password is entered. You can start the utility by pressing Enter instead of entering the supervisor password; however, you cannot change the parameters that are protected by the supervisor password. On the BIOS Setup Utility screen, press F9, Enter, F10, and then Enter. Note: When you initialize the computer configuration, some devices are disabled, such as the serial port. If you test one of these devices, you will need to enable it by using Configuration utility for DOS. The utility is available on the following Web site: http://www.lenovo.com/support Testing the computer To run the test, do as follows: Note: In the following procedure, you can select an item not only with the arrow keys, but also with the TrackPoint ® pointer. Instead of pressing Enter, click the left button. 1. Insert the PC-Doctor disk into the diskette drive; then power on the computer. If the computer cannot be powered on, go to “Power system checkout” on page 29, and check the power sources. If an error code appears, go to “Symptom-to-FRU index” on page 39. On the first screen, select the model and press Enter. Follow the instructions on the screen. 2. The main panel of PC-Doctor appears. 26 ThinkPad X300 Hardware Maintenance Manual Note: PC-Doctor for DOS is available at following Web site: http://www.lenovo.com/ support To create the PC-Doctor diagnostic diskette, follow the instruction on the Web site. 3.
