1. Turn off the system and any attached peripherals (if applicable).

2. Verify that all power cables are properly connected to the system, the monitor, and peripherals, and check their power sources.

3. Inspect connections to any attached devices, including network cables, keyboard, monitor, and mouse.

3.2.2 Performing an Internal Visual Inspection

1. Shut down the operating system, if necessary, and turn off the platform power on the front of the workstation.

2. Turn off the AC power on the back of the workstation.

3. Turn off any attached peripherals, but do not disconnect the power cables.

4. Remove the left side access panel, following the procedures in Section 5.2,

“Opening the Workstation” on page 5-2.

Caution – Some components, such as the heatsink, can become extremely hot

during system operations. Allow these components to cool before handling them.

Chapter 3 Troubleshooting 3-3

5. Verify that the components are fully seated in their sockets or connectors and that the sockets are clean.

6. Verify that all cables inside the system are firmly attached to their appropriate connectors.

7. Replace the left side access panel.

4.5 Immediate Burn-In Testing

The Immediate Burn-In Testing option enables you to run burn-in test scripts on your workstation. Three scripts were created for testing your system:

■ quick.tst – This script performs a non-detailed test of all hardware

components, including those components that require user input, as well as a more in-depth memory test. You must interact with the Pc-Check software to progress through these interactive tests. These interactive tests cannot be run unattended and do not contain any “timeout” facilities. The interactive tests will wait until the user provides the correct input.

■ noinput.tst – This script is used as a first triage of any hardware-related

problems or issues. The script performs a non-detailed test of most hardware components, excluding those components that require user input (keyboard, mouse, sound, video). This test does not require user input.

■ full.tst – This script performs the most detailed and comprehensive test on all

hardware components, including those components which require user input. This script contains a more in-depth memory test than quick.tst, as well as external port tests (which might require loopback connectors). You must interact with the test utility to progress through these interactive tests.

Tip – Each of these scripts tests the operating status of your entire system. If you

want to test only a certain percentage of your system’s hard drives, refer to

Section 4.4.1, “Hard Disk Drive Testing” on page 4-6 to change the test options.
