BIOS Recovery Hp 68AZZ From USB?

  • 0

I have a HP Probook 4520s laptop. Recently, after a “critical” automatic update from HP, it flashed a new BIOS update. The update worked, but on the final restart it just started an on/off cycle. I left it for an hour, then unplugged the power because it was clear that the bios was not working.

I tried the following method from a forum:

1. Get a USB memory stick that is <= 4GB and format it to FAT (FAT16) in windows. (It doesn’t work to use a larger memory stick formatted to FAT, or a memory stick formatted to FAT32)
2. Make this directory structure on the USB memory: \HEWLETT-PACKARD\BIOS\CURRENT\
3. Download the Softpack with the BIOS update for your system from the HP website. Extract the spxxxxx.exe with winrar or a similar software, or run the program and look in the C:\SWSetup\spxxxxx\Rompaq\ directory for a file called 68XXX.bin (XXX differs on different systems).
4. Copy 68XXX.bin into the \HEWLETT-PACKARD\BIOS\CURRENT\ directory on the USB memory.
5. Open the archive C:\SWSetup\spxxxxx\Rom.cab and extract efibios.sig to the \HEWLETT-PACKARD\BIOS\CURRENT\ directory. Rename efibios.sig to 68XXX.sig (replace XXX with the same letters as in your 68XXX.bin).
6. Insert the USB memory stick into a USB port on your computer. While pressing Win+B, power up the system.
7. The Caps lock led will flash continously, and the computer will read the file from the USB stick.
8. In under a minute the system will shut down. Remove the USB stick. The system will power up again and immediatly shut down. The system will power up again, and you will be greeted with a screen that says the your BIOS was recovered. 🙂

The PC read the flash drive for 10 seconds then shut off. I also tried a SD card and CD. Am I doing anything wrong? Am I downloading the wrong version to flash? (First BIOS version, factory) Thanks

  1. I can’t say why HP did any critical bios update. If so then I’d contact them. They need to fix this issue.
    Generally I try to discourage any attempts to update bios.

  2. Bios updates are NEVER flashed automatically. If the HP update feature offered it, you would have to have given permission for it to be installed.

    It sounds like the flash chip has PHYSICALLY FAILED.

    Have a computer technician examine your computer.
    ……….

    Flashing the bios is the riskiest thing you can do with a computer !

    Even if you do everything right, the cheap flash chip used for bioses has a high failure rate and can physically faiI while flashing, sometimes the FIRST time you try flashing.

    You can’t recover from that yourself unless the bios chip is in a socket and is removable and you can buy an already programmed flash chip to replace it with.
    In most cases these days it isn’t removable – it’s soldered into the mboard and can only be replaced with a new chip by a professional who has the proper equipment – that can cost as much as a new or used replacement mboard does or more.
    ……………

    You DO NOT flash the bios unless you absolutely have to !

    In most cases, the ONLY legitimate reason for flashing the bios is when you have installed a CPU the present bios version doesn’t support recognizing, or when you’re having a problem that is mentioned in the release notes for the bios update, or any newer bios update than your computer presently has, and HP usually does NOT provide that info for either of those things !

    The safest way of flashing the bios is by NOT doing it with a Windows program !

    If you were EVER NOT having a problem caused by the present bios version, it MAKES NO SENSE AT ALL to flash the bios because the problem is NOT caused by the present bios version !
