HP Notebook PCs - System Diagnostics (F2)
This document pertains to HP Notebook PCs with the HP Unified Extensible Firmware Interface (UEFI) beginning in late-2008.
To access the UEFI System Diagnostics, turn on the computer and immediately press the esc key to display the Startup Menu, and then press the F2 key.
The System Diagnostics window allows you to run several diagnostic tests. Each test determines if the hardware is functioning properly, and displays an error message and a warranty ID if there is a hardware failure.
Obtain the latest update
The UEFI System Diagnostic is available on most HP notebook PCs, manufactured after late-2008. An updated BIOS and updated System DIAGNOSTIC may be available for your computer. If so, download and install the BIOS and then install the UEFI. On the Software & Driver Downloads page, select both the BIOS and the HP System Diagnostics (UEFI) updates. See Locating HP Software, Driver and BIOS Updates .
Select the F2 option on the Startup Menu to access the following diagnostic tests. Most of the test will run until you press the esc key to cancel.
Failure Code Format
If you see a failure code after the system diagnostic tests complete, write it down and contact HP for support. Otherwise, the agent may want you to go through the diagnostic testing process again to obtain the failure ID.
The HP failure code contains four fields of six characters each, such as, where X is an alpha-numeric character.
NOTE: Having a failure code does not mean that your computer is still under warranty. The warranty start date on the computer determines if it is still under warranty. The agent can assist you with this when you contact HP.
The BIOS displays the following error codes and messages. The error code consists of two parts. The first byte represents the Field Replaceable Unit (FRU), and the second byte represents the test that failed. If you receive an error code, contact HP with the Error Code for assistance. You are encouraged to contact an HP support agent for assistance because an error code may indicate different conditions or corrective actions depending on the specific models.
