boot problem



You get a LONG (MAJOR) signal category, RED LED &

then a SHORT (MINOR) signal category, WHITE LED.

Major – the category of the error; Minor – specific error in that category

The AUDIBLE repeats 5 times, and the VISUAL until power is removed.






The embedded controller times out waiting for the BIOS.

Component is not reachable by BIOS in certain time limit.

1 Reseat component.

2 Test known good component.

3 Replace component or Main-Board as needed.


IF it is a potential BIOS problem, then....

Hopefully one of these documents will cover (and solve) your problem...

Turn off the computer, and then connect the power cord.
Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
HP BIOS Update recovery in progress

If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

Little Boy Blue, come blow your horn.
