Corrupted Bios 844C and CMOS on a HP Pavlilion 790-0901during an automatic scheduled update.

HP Pavlilion 790-0901
Microsoft Windows 10 (64-bit)

Corrupted Bios 844C and CMOS on a HP Pavlilion 790-0901during an automatic scheduled update if HP support assistant.  Bios does not boot, computer freeze , and none F10, F1, F2, F11 or F12 works

Already done:

  1 Recover bios from CMOS with Windows Key and V simultaneously.  Does not work because CMOS is also corrupted.

  2 Tried to reboot with USB Flash bios tools created on another HP computer and procedure 1 above.  Does not work with version 4.1 nor 4.2 of the flash bios. 

 3 Tried to reset the CMOS by removing the battery and redo procedure 2 above.  Same result the Bios does not loaded and the computer freezes there. 

What do I do next?

 

  As long as the bios is not repaired, I cannot use any diagnostic from HP or Windows, and I cannot mount a system back up.

 

Thank you

I reviewed your post and I understand that the BIOS is corrupt on the computer.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

I see that you have already followed all the relevant troubleshooting steps and I recommend you contact support and check the available service options for your computer.

 

Here is how you can get in touch with support.

 

1)Click on this link – www.hp.com/contacthp/

2)Select the product type.

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.

 

Let me know how it goes and you have a great day!

Thank you very much for your assistance and great help.

I registered for support and phone them when I got the case number and phone number.  They diagnose that the problem was 'probably' related to a faulty motherboard.   And this is where I became most frustrated.

The one-year warrantee on my HP 790-0109 has ended recently on January 31, 2021.  The machine was working perfectly well just before the BIOS update.  During the update there was no electric power outage that could have damage the system.  It just froze at the HP Logo while rebooting.

Because a problem cause by an update with an HP softpack,  I have to pay $350, send my recent computer to the service shop, and loose my machine for 10 days.  All of this after spending another 10 days, diagnosing, searching and trying possible HP solutions.

As I said, it is just over a year that I have this computer.  Last year at the end of  March, I had already lost about a month after a 'Frozen blue screen problem' due once again to an HP update.  It took about a month to HP to figure out the that there was a conflict between an Intel driver installed during the HP update and a new official version of Windows 10.

Will it be possible to carry the message to your management that they ought to more extensively test their Softpack update before putting it for large main stream distribution.

Thank you
