Identify the issue 1. Understand the issue It is important to understand the issue that occurred, including related symptoms. It helps to understand the basic computer boot-up sequence as well as the failure itself. The boot-up sequence and associated failures are described below. Boot up sequence The computer performs several steps after you press the power button or restart the computer. It is important to understand where in the boot-up sequence the symptoms occur.
A single symptom can be listed under different groups. For example, No Video can belong to (1) Power-on or (4) Display; but Flickering when powered should be listed in (4) Display. Or, in another example, a blue screen can be caused by a driver conflict in Performance (4), but it can also be caused by a defective hard drive under (6) Storage. Therefore, failures that share similar symptoms are noted.
Failure classification by hardware devices and mechanical Table 8-5 Failure classification by hardware devices and mechanical 4. Display 5. I/O devices 6. Storage 7. Mechanical 1.

3. Perform a visual inspection of hardware It is important to do a visual inspection of the hardware itself. Perform physical inspection of the computer: ● Look for abnormalities such as a cracked display, dented battery, broken latches for battery bay, keyboard key caps popped out, dust over connectors, liquid spill over keyboard, etc. ● Look for signs of drop, movement, or vibration that may cause internal and external loose connections. 4.
6. HP Hardware Diagnostics and Tools HP offers different diagnostics and tools to diagnose hardware failure. This section describes how to use some of these tools. Make sure to check for the latest versions before use. HP PC Hardware Diagnostics (UEFI) HP PC Hardware Diagnostics is a Unified Extensible Firmware Interface (UEFI) that allows you to run diagnostic tests to determine whether the computer hardware is functioning properly.
2. When the diagnostic tool opens, use the keyboard arrow keys to select the type of diagnostic test you want to run, and then follow the on-screen instructions. Screen shot appearance may vary. NOTE: Users should utilize this tool, especially when the computer cannot boot to Windows. NOTE: If a component fails a test, write down the information so it is available when contacting support. The information is also available in Test Logs on the Main Menu.
HP BIOS Configuration Utility (BCU) HP BCU is a free utility that captures the BIOS settings and their values. This tool provides a text file of the computer’s BIOS configuration. This can help identify any settings that may be contributing to an issue. In some cases, it may help to compare this BIOS text file to the default settings of the computer. For more information, see the http://ftp.hp.com/pub/caps-softpaq/cmit/whitepapers/ BIOS_Configuration_Utility_User_Guide.pdf.
7. Status lights, blinking light codes, troubleshooting lights, and POST error messages Carefully observe any behavior the computer may be exhibiting: status lights, blinking lights, and POST error messages during boot. It is important to understand what these indicators mean. Status lights See the chapter titled “External Component Identification” for light locations. The following table describes basic lights on the computer.
