How to reflash corrupt bios

[khutch9999]

My HP DV6Z-1100 has the Caps and Num lock flashing twice then wait then twice again which from the HP website says my bios is corrupt.  How can I reload the bios without a working bios.  Tried downloading the latest Bios file and following the steps on HP support site but they are not what I am seeing.  They talk about creating a bootable flash drive with their winflash file but that doesn't allow for the creation of a bios bootable flash disk to reflash the bios with.

Hi

HP Pavilion dv6z-1100 CTO Entertainment Notebook PC

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).

Type:  BIOS    Version:   F.18 Rev.

Operating systems:   Windows 7 (64-bit)

Release date:    Nov 20, 2009

File name:   sp46500.exe        (3.1 MB)

Description:

This package contains the WinFlash Utility and a system BIOS image for the supported notebook/laptop models and operating systems. The WinFlash Utility is used to locally flash the system BIOS (ROM) on notebooks/laptops operating in a Microsoft Windows Vista operating environment.

Fix and enhancements:

Activates the hard drive security freeze lock feature during the Power-On Self-Test (POST), which helps to prevent malware or third-party software from locking the hard drive without authorization after POST.

If in doubt please ask.

I tried both of the things you stated in your reply but neither worked.  (khuthc9999) Could not sign on with khutch9999 as it did not recognize my screen name and had to create a new one.

1. Hold down the windows and B key then press power and hold for 2 to 3 seconds.  Then continue to hold the windows and B key.  I held them for over 1 minute and nothing happened.

2.  Hold down the windows and V key then press power and hold for 2 to 3 seconds.  Then continue to hold the windows and V key.  I held them for over 1 minute and nothing happened.

3. The WinFlash utility only works when you can access the bios of the PC.  Using the two methods above I get nothing and cannot use the WinFlash Utility is not an option as I only get the flashing caps/num lock LEDs.

CF4 - I have tried all these things.  The computer never beeps, the caps and num lock LEDs flash two times then after a few seconds flash twice again.  Per the help pages that indicates a corrupt bios.  When trying the window button/B or V buttons nothing happens.  I followed the steps and held them for 5 minutes and nothing.  I tried removing the battery memory and HDD and with only the power supply turning the PC on and still just the caps and num lock flashing LEDs twice.  I replaced the main board and I get the same thing.  At that point I removed the optical drive and tried again but with the same results.  I even tried to reload the bios with a USB drive formated to boot with HP Tools.  Not sure what else to try.  Could the keyboard be the issue?????

You stated that you "replaced the main board "?

Kindly elaborate on that.

[hutch9999]

I purchased a new mother board, CPU and installed it into my machine and it did the same thing as far as the caps and num lock LEDs blinking twice when powered on.

Interesting.

Are you aware that the system board needs to be tattooed with HP's proprietary utility to put the systemboard information in the BIOS?  It is a DMI tool.

You would be better off with the original board in the notebook.  The BIOS in the new board may not even have been flashed with a ROM file yet. That may be why it is giving you problems.

There is a utility at the HP PC Hardware Diagnostics web document called an HP PC HARDWARE DIAGNOSTICS 4-IN-1 USB KEY that should allow you to rectify the issue.  I have used it a few times on BIOS corruption issues. You will need an 8-16 GB formatted USB flash drive to create the key. Once you start creating the key you will have to be patient. In my own experience, even on a fast system (4.7 GHz octo processor) it will take at least several minutes to create the 4-IN-1 USB key.

There are instructions on how to use the different options of the USB  key in a MSWord document in the folder of the softpaq. Download it and use 7-Zip to extract it to a folder.

If you are refering to the HP PC Hardware Diagnostics 3 in 1 key I tried that.  Still does not work..  PC does not recognize the USB port.

Found the 4-in1 key and downloading it now. Will follow instructions and reply with results.  Thank you.
