How do I fix corrupted BIOS? tx2500

My tx2500 gives the double LED flash that signals it has a corrupted BIOS.  According to this URL you can "restore BIOS from onboard backup (jumpers)."  If anybody has an idea what this means and how to fix my computer I would be very thankful.

Re: How do I fix corrupted BIOS? tx2500

Here are two possible methods to restore that BIOS:

 

=====================================================================================

Option:  see if your system can Restore the BIOS:

 

Select your Notebook from this List of tx2500 Series

 

Go to:

Solve a Problem > Memory (RAM) / Motherboards / BIOS > BIOS / UEFI > Restoring the BIOS

 

For example, if the HP Pavilion tx2500 CTO is your notebook, then this is your Page:  Restoring the BIOS

 

---------------------------------------------------------------------------------------------------------------------------------------

Option - Use the UEFI environment to Restore the BIOS

 

  • From a Complete shut down condition (all off),
  • Press the power button and
  • Immediately tap the ESC key to get into the "Start Menu"
  • Select "F2" to start the HP Advanced Systems Diagnostics menu screen
  • Select BIOS / Firmware Management

--------------------------------------------------------------------------------------------------------------------------------------

Option - Download the BIOS file from your notebook's own webpage -- Software and Downloads section

 

  • Extract the contents and put the files onto the root of a USB thumbdrive
  • Connect the thumbdrive to a USB 2.0 port on your system
  • Connect the AC power adapter.
  • From a complete shut down condition (all off),
  • Press the power button and
  • Immediately hold the Windows key while tapping on the "B" key
  • The BIOS update process should start
  • Follow the prompts to restore your BIOS, using the BIOS file on your thumbdrive

Also from erico:

===================================================================================

Thanks for the reply, but neither of these worked. The computer beeps, but the screen stays black and the LEDs keep flashing

Re: How do I fix corrupted BIOS? tx2500

The root cause of the problem is not necessarily the BIOS.

 

The number of beeps and flashes is usually indicative of the underlying issue; in some cases the problem is admittedly more difficult to track down.

And, less likely, but a good resource for component testing:

Re: How do I fix corrupted BIOS? tx2500

I fixed the BIOS problem by taking out half of the RAM. Now the computer partially boots windows and the screen freezes which I have read is a permanent problem.
