Visual Inspection

The visual inspection consists of a quick inspection of the exterior of the computer and any attached peripherals, including making any necessary corrections. For information about the proper removal and installation of computer components, as instructed in the following procedures, see Chapter 4, "Removing and Replacing Parts."

CAUTION: Before you proceed with the visual inspection, ensure that the user has saved all open files and exited all open application programs if possible.

To perform a visual inspection, follow these steps:

1. Turn off any attached peripherals.

2. Determine the present power state of the computer.

Look at the indicators to determine which of the following conditions apply, and then turn off the computer, taking the actions listed for that condition:

• Power/suspend indicator is blinking approximately every 8 seconds — The computer is in suspend mode. Open the display and press any key to return the computer to the power-on state. If the computer does not turn on, press <FN><B> to return from battery-swap mode. Then slide the power button to turn off the computer.

• Low-battery indicator is on or blinking — A low-battery warning occurred; open the display and slide the power button to turn off the computer.

• Low-battery and charging indicators are both blinking — A defective battery is detected or the computer is too warm; slide the power button to turn off the computer.

• All indicators remain off — The computer is already turned off or is in suspend-to-disk mode.

3. Verify that the exterior of the computer is free of any obvious physical damage.

4. If the computer is operating from an AC adapter, verify the following:

• The AC adapter's AC power cable is connected to the AC adapter and the power source.

• The AC adapter's DC power cable is properly connected to the computer's DC power input connector.

• The AC adapter and cables are free of any obvious physical damage.

NOTE: If the charging indicator and low-battery indicator flash continuously while the computer is connected to AC power, disconnect the computer from AC power and move it to a cooler location. When the computer has cooled to room temperature, reconnect it to AC power and continue charging the battery. If the computer is not allowed to cool, the battery stops charging before it reaches full capacity.

5. If the computer is operating from battery power, remove the main battery assembly, verify that it is free of any obvious physical damage, and then reinsert the battery assembly into its compartment.

6. Turn off the computer. Remove the hard-disk drive, verify that it is free of any obvious physical damage, and then reinsert the drive into its compartment.

7. Remove any installed PC Cards from the PC Card slot, verify that they are free of any obvious physical damage, and then reinsert the card(s) into the PC Card slot.

8. Remove any memory modules from the memory compartment, verify that they are free of any obvious damage, and then reinstall the memory modules.

9. Open the display assembly, and verify that it is free of any obvious physical damage.

10. Verify that the internal keyboard is free of any obvious physical damage and that its keys operate freely.

11. Verify that the trackball and its associated switches operate freely.

12. If an external monitor is connected, verify the following:

• The monitor's interface cable is properly attached to the VGA connector on the I/O panel.

• The monitor's power cable is attached to a power source and is free of any obvious physical damage.

• The monitor's controls are set according to the instructions in the documentation for the monitor.

• The monitor and its interface cable are free of any obvious physical damage.

13. If an external mouse is connected, verify the following:

• The mouse is properly connected to the keyboard/keypad/mouse connector on the computer's I/O panel.

• The mouse and its cable are free of any obvious physical damage.

• The mouse's ball and push buttons operate freely.

14. For any attached serial or parallel devices, verify the following:

• The device's interface cable connector is correctly attached to the appropriate port connector on the computer's I/O panel.

• The captive screws that secure the connectors at each end of the interface cable are secure enough to ensure a firm connection.

• The attached device and its interface cable are free of any obvious physical damage.

15. Turn on any attached peripherals and then the computer.

Does the problem reoccur?

Yes. Proceed to the next procedure, "Observing the Boot Routine." No. No further steps are necessary.
