Symptoms
● Computer has power
● POST error message displays
(Windows logo has not yet
appeared)
Possible causes
Diagnostic error messages indicate a problem. There may be a problem with the instruction
being sent from the BIOS to a hardware component (for example, keyboard failures), or
incompatible hardware. Can usually be resolved by installing updated rmware for the
component.
Troubleshooting steps
1. See 7. Status lights, blinking light codes, troubleshooting lights, and POST error
messages on page 112 for corrective actions. An example of a POST error message
might be "Boot Device Not Found."
2. If there is power, you might be able to access BIOS. Reset BIOS to its default condition.
(9. Soft reset (Default Settings) on page 116)
3. Restore hardware to its original condition (for example, bootable solid-state drive
instead of hard drive).
4. Reseat suspected components and verify connection.
5. Test suspected components using HP PC Hardware Diagnostics (UEFI) tool.
Note An Error Message means that the system has nished BIOS hardware validation and is ready
to launch the Startup Menu. To access the Startup Menu for further options, press the esc key
while restarting the computer.
