Bios corrompu 2 longs bips - 4 bips rapides

[letal]

Bonjour,

Après une une mise à jour du Bios: 2.33 (si mes souvenir sont exact), il doit redemarrer, je clique OK, il reboot, mais écran noir et plus rien!

La led du bouton on/off clignote 1 fois toute les 10 sec. (sans fin) et rien...

Au bout de 10min. Je débranche et rebranche l'alim. et là:

1. Deux longs bid (led rouge)
2. Quatre bip court (led blanche)

Je ne trouve aucune info sur le net ou HP pour faire un clear CMOS, est-ce différent avec un bios UEFI???

J'ai testé la mémoire, emplacement différent, autre barette, autre SSD, toujours rien!

Quand je débranche et rebranche l'alim. toujours les mêmes bip.

Une idée?

Merci

Hi

Please try this...

Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key and the B key at the same time (WinKey +B).

NB: On some notebook models, it might be necessary to press and hold the Windows logo key and the V key (WinKey +V).

While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

Firstly, thank you for your reply!

Its not a notebook, its an eliteDesk G2 800, I don't know if the recovery process word just as the same?

So I did give a try but no luck!

The computer is in a strange state: off for 10sec and then fan spining, power led on for 10 sec then back to off for 10 sec and again and again...

On the inside there is a push button, what for? I did give a try, no success...

Any idea?

First run a Diagnostic on the hardware, probably F2.

BIOS

2.2 The main area (DXE) of BIOS has become corrupted and there is no recovery binary image available.

2.3 The embedded controller policy requires the user to enter a key sequence.

2.4 The embedded controller is checking or recovering the boot block.

Locate, press, and hold the CMOS button in for  5 seconds.

 If in doubt please ask.

Did not work, nothing happened what ever I do!

I gave up. I did spend to much time on this case.

Thanks anyway

Hi,

No I don't! So I did download it to another same pc and install it, what next?

Hi

I'm confused.

I downloaded the BIOS file and extracted on my PC, even though it is completely the wrong BIOS and will never get installed.

So if you can't download and extract the *.exe file then......
