[. . . ] Try to re-create the failure by running the diagnostic test or by repeating the operation. Testing the computer The ThinkPad computer has a test program called PC-Doctor® 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 "Product overview" on page 45. 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 SONY BIOS Setup Utility before you run PC-Doctor. On the SONY 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 PS2. EXE. PC-Doctor cannot be used to test a device that is in the docking station, even if the computer supports the docking station. To test a USB device, connect it to the USB connector of the computer. To test the Ultrabay device, install it in the Ultrabay Plus slot of the computer. v If the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation. v If the computer does not charge during operation, go to Checking operational charging.

See the following figure: Pin Voltage (V dc) +15. 5 to +17. 0 Ground (16 - 10 V) 3. If the voltage is not correct, replace the ac adapter. If the voltage is acceptable, do the following: v Replace the system board. 2 1 1 2 General descriptions 39 Checkout guide v If the problem persists, go to "Product overview" on page 45. Note: Noise from the ac adapter does not always indicate a defect. Checking operational charging To check whether the battery charges properly during operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. If the charge indicator or icon still does not turn on, replace the battery pack.
