[. . . ] 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/think/ support 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 create the PC-Doctor disk from the Access SONY Predesktop Area, do as follows: 1. Enter the SONY Predesktop application by pressing the Access SONY button during POST. When the Access SONY application finishes loading, double-click the "Create Diagnostic Diskettes" icon. It will take about 15 seconds to authenticate the digital signature, and then the ThinkPad computer will reboot into PC-DOS. 4. A batch file will automatically start up to prompt the user through creating the boot diskettes. Typically, the user only needs to press the Enter key for the proper floppy drive to format and create the diskette. Note: Noise from the ac adapter does not always indicate a defect. 44 MT 2672, 2673, 2884, 2885 Checkout guide 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. If the charge indicator still does not turn on, replace the system board. If it is still not charged, go to the next section. Checking the battery pack Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. To check the status of your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Remove it from the computer and leave it at room temperature for a while. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 5 (-). See the following figure: Terminal Voltage (V dc) + 0 to + 12. 6 Ground (-) 5(-) 4 3 2 1(+) 1 5 3.
