� Touch pad test... Tests the touch pad. Tests whether the cursor moves, and whether right-clicking and left-clicking function properly. The dialog box appears three times. Move the cursor to the box that appears. The tests are performed in the following order. (1) Touch pad (2) Left-click button (3) Right-click button (Two times) � Serial loopback test... Performs the loopback test of the serial port. Connect the port replicator and the loopback tool to the serial port. � Parallel loopback test... Performs the loopback test of the parallel port. Connect the port replicator and loopback tool to the parallel port. � PC card Slot test... Tests the PC card slot. Implements the 16-bit/card-bus test for the two slots of the main unit. � Video test... NOTE: Because this test is performed by visual inspection, confirm first the normal video picture, then start the test. Tests the video signal. Several video patterns appear every time the key is pressed. The person conducting the test must visually check whether the patterns appear properly. Press Y when there is no abnormality. � PPK test... Tests the PPK. If the test is not completed within the specified time, an error is triggered due to the time-out set for this test. When two or more PPKs are set, follow the instructions that appear on the screen. � GUID test... This test is not required normally. Displays the GUID (i.Link ID value), and judges whether the value on the display is appropriate. � IEEE 1394 Interface test... Performs the 1394 communication test. Another personal computer to communicate with is necessary for this test. The models released from the year 2000 have already been confirmed that they do not cause any problems regarding the IEEE1394 interface. Even models released before 2000 will cause no problem if the same type of IEEE1394 interface IC chip (the IC chip used in the iLink block connected to the PCI bus) is used in both personal computers that are connected. In other combinations, the IEEE1394 interface test is not confirmed. (Use of the models released from the year 2000 is recommended.) 1. Connect the iLink cable. 2. Start up the personal computer at the other end of the IEEE1394 interface test connection using the tool floppy disk that must be created beforehand by copying programs from the service diagnostics CD disc. (Prepare a floppy disk that is formatted to contain the DOS system. Create a tool floppy disk by copying the entire TOOL folder of the CD disc to a floppy disk.) 3. Select the 1394 test from the menu at the connected computer to enter the reception state. 4. After the connected personal computer has entered the reception state, select the 1394 test at the personal computer to be tested. The IEEE1394 interface test then starts. Send and receive of the random data are repeated five times (i.e., this test is repeated five times.)
