Hi, I do this operation on my HP z840: I disable all POST ROM messages in all PCI slot from bios setup and after reboot system start with 6 beeps. How is it possible to return to default data?

 

Thank you

Try this: 

1. shut down the PC

2. pull the power cable

3. push and hold the power button for at least 15 seconds

 

OR try this:

👉SUBSCRIBE! If you are getting BIOS boot errors (beep code, red LED) on your HP Z820 and pressing the clear CMOS button is not working, you can try removing the CMOS battery. YOUR PC MUST BE UNPLUGGED FROM THE WALL! Do not try this first! You should try pressing the clear CMOS button before you do

Hi, nothing ... always 6 beeps

 

we try to load bios from USB with jump moved from 2-3 to 1-2, but the same ...

Unfortunately i don't have another solution for you.

I am also dealing right now with the same 6 beeps.

But my beeps start when I install radeon vega 64 on a Z820.

Always works fine till my collegue decide to change property on PCI download ROM

Have you trieds to enter the BIOS during startup and applied Apply Factory Defaults and Exit?

 

If it don´t do the trick, go to page 91 in the manual for more help: http://h10032.www1.hp.com/ctg/Manual/c04823811

Hi, I can’t enter in the bios setup, after disabled all ROM POST and save, system reboot and start with 6 beeps. 

 

I try to load bios via USB but nothing. I try to force boot with windows key and B plus USB, nothing. Try to change different Grapghic cards and their position. Noting

 

probably the only one solution is to “correct” bios with a Service HP, but I need to speak with them on monday

On my Z440 i use the ESC key, what key do you use?

HP Recommended

I just do all this, no possibility to press keys... no output signal. Only beeps

If possible, try with another graphic card.

 

Has the current graphic card ever worked?
