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 T61 and T61p (14.1-inch)” on page 47.

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.

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

PC-Doctor cannot be used to test a device that is in the ThinkPad Advanced Dock, even if the computer supports the ThinkPad Advanced Dock. To test a USB device, connect it to the USB connector of the computer.
