HP 280 G1 MT BIOS update, black screen recovery

HP Recommended
HP 280 G1 MT
Microsoft Windows 8.1 (64-bit)

Hi, I have a problem with HP 280 G1 MT.

I was upgrading the bios and now I can't start the BIOS.

Black screen, keyboard no lights. Im trying Win + B and but, keybord isnt responding. 

Im heared 8 beep code sometimes, but after a minute there will be no bios on the monitor.

Can you give me please advice?

 

Thank you.

Hi

You have a Personal Computer, the links cover your situation to a certain extent.

 

EG:

  1. With the computer off, press and hold the Windows key and the B key at the same time.
  2. Still 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 and B keys until the BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

~~~~~~~~~~~~~~~~

The power LED light remains on, and the screen remains blank for about 40 seconds before anything displays on the monitor. You might also hear beeping sounds. Eventually, an HP BIOS Update screen displays and the BIOS update begins automatically.
~~~~~~~~~~~~~~~~~~~~~
 
  • If the HP BIOS Update screen does not display, do one of the following depending on the condition:
  • Computer starts into Windows: The computer starts into Windows if the power button and keys are released too soon. Repeat the previous steps, holding the power button down for 2 or 3 seconds.
  • Power LED light turns off: The computer turns off if the power button is pressed and held down too long. Repeat the previous steps, holding the power button down for between 2 and 3 seconds.
  • After repeated attempts, the HP BIOS Update screen does not open: Your computer does not support this function or it has a hardware problem that is preventing the tool from opening.

~~~~~~~~~~~~~~~~~~~

 

Maybe

  • One (1) VGA
  • One (1) DVI-D

is where the problem is?

 

I  cannot offer anything else with the info you have so far supplied.

 

Bye.
