Chapter 4 Troubleshooting System Check Procedures External Diskette Drive Check Do the following steps to isolate the problem to a controller, driver, or diskette. A write-enabled, diagnostic diskette is required. NOTE: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device. 1. The FDD heads can become dirty over time, affecting their performance.
Keyboard or Auxiliary Input Device Check Remove the external keyboard if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated in the connector on the main board. If the keyboard cable connection is correct, run the Keyboard Test. If the tests detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a non-defective FRU: 1.
Check the Power Adapter Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power adapter cable. See the following figure Pin 1: 19V Pin 2: 0V, Ground 1. If the voltage is not correct, replace the power adapter. 2. If the voltage is within the range, do the following: T Replace the main board. T If the problem is not corrected, see “Undetermined Problems” on page 62. T If the voltage is not correct, go to the next step.
Check the Battery Pack To check the battery pack, do the following: From Software: 1. Check out the Power Options in control Panel 2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. 3. Repeat the steps 1 and 2, for both battery and adapter. 4. This helps you identify first the problem is on recharging or discharging. From Hardware: 1. Power off the computer. 2.
still occurs, continue next step. Replace the CPU with another of the same specifications. If the problems still occurs, go to next step. The main board may be damaged. Replace main board. 3. If the external monitor has the same problem as the internal monitor, the main board may be damaged. Please insert the diagnostic disk and run the display test program and go through the sub-steps under step 2.
