HP Compaq BIOS Crisis Recovery from a Failed BIOS Flashing Using a USB Flash Disk

I tried to flash my HP Compaq CQ35-240TX’s BIOS to F.15 but unfortunately failed. The computer turned to white screen. When I restarted (powered off then boot again), this is no response any more: the hard disk and caps lock’s LED keep blinding. I thought “Oh my God! I must send it to HP to repair it!”.

But after searching on the Internet and find there is a “crisis recovery” mechanism to recovery the BIOS even the CMOS don’t work. I finally managed to recovery the BIOS with a help of USB flash disk. I will introduce the procedure to crisis recovery my HP Compaq laptop. You need to prepare a USB flash disk and another computer that is connected to the Internet (we need to download the BIOS image from HP).

The steps to recovery the BIOS are as follows.

1. Format the USB flash disk’s filesystem to FAT16 on another computer.

2. Get the BIOS image from HP’s website (I use F15 version).

Download the BIOS update file from HP’s website (an exe file). Execute the BIOS update file on another computer. It will decompress the files. Select a directory to store the files and you can close the program. In the directory selected, we can get WinFlash.exe. Unzip WinFlash.exe using a program like WinRAR. We can find two .FD files. For my computer and the BIOS version I use, the two files are 306DF15.FD and 306EF15.FD. There are two model for Compaq CQ35 computers, so there are two .FD files. You may try one by one to see which model your computer use. Actually this model can be found in “BIOS Setup” (we can’t start it as the CMOS is bad)

3. Copy the file 306DF15.FD to USB disk’s root directory and rename it to 306D.bin. (the file may be different depending on the model)

4. Remove the AC power and battery from the lapttop.

5. Plug in the USB flash disk to the laptop.

6. Hold two keys: WinKey + B.

7. Plug in the AC power.

8. Hold the Power Button for 5 seconds, then release.

9. Push the Power button as normal to power on the computer.

10. After the laptop starts short beeping, release WinKey+B.

11. The laptop will keep short beeping for about one minute, it will power off itself after recovering the BIOS. If the laptop keeps long beeping or beeping for more than 3 minutes, the recovery fails, possibly because of the wrong image file or the USB flash disk doesn’t work on the laptop. In this case, you may try another image file or another USB flash disk.

Normally power on the laptop after recovering the BIOS and you will see the Compaq logo appearing again.

Disclaimer: I just tested the method in the post with my laptop and am not sure whether it works with one specific model (although it seems work for some others according to the comments). The method in the post is just one example solution. If your data is critical, contact a professional, such as the customer service from HP, to repair it for you.


Update 1:

Vadim‘s experience with HP Pavilion dv6740er may help if you have a similar model:

  2. I,m using HP 630,I3 Laptop.i’m also have the problem with power on with black screen please help..

    1. Have you tried the method in Update 1 (Vadim‘s experience)? If it does not help, I am afraid the models and BIOS recovery method from HP have already changed since my CQ35 is bought in 2009. After that, I have not touched any other HP laptops.

    1. Haswell (2013) models like mine is 17-J029nr. Bricked BIOS and tried to copy many things over to the flash drive and tried .fd/.bin/.this&that and nothing works…

  3. Hey i have same error with yannick. The bios instalation seems to be installed… but the computer doesnt shut down on its on….

  4. My CQ61-315SG does everything as described, exept it does not power off after recovery – and after force off and restart, it comes again with the blinking bios error code…

  5. Hi,

    I’m trying to restore bios on HP DV 6274ea who refused to boot properly after a bios upgrade with hp bios upgrade exe.
    At startup the laptop lights up but screen remains dark and very loud beeps (one long and two shorts) never stop.

    I have tried with usb stick and floppy disk. I dowloaded the latest bios from HP, extracted the XXXXX.WPH and renamed it in BIOS.WPH and copied it in the usb stick or floppy with WINCRISIS (and making it bootable of course).

    When i try the classical restoring process with Windows+B key, the laptop reads the floppy (or usb key) content and shut off after some minutes. But when i start it up again, the same beeps and nothing en screen.

    I also tried to only put bios on floppy (or usb key) renamed in .BIN. Nothing more…

    Any suggestion ?

    Thanks.
    Joss

  6. I tried this but it didnt work for my CQ56 trying to load F18 BIOS. My computer had quit with the flashing LED indicating a CPU failure. I replaced the CPU but nothing changed. I downloaded the BIOS file and followed the directions but my computer never beeped at all. It still shows a flashing LED indicating CPU failure. On startup all I get is a black screen with the power light on and the flashing LED on the Caps Lock button. I’m thinking it’s a hardware failure, possibly in the power supply. Ideas?

    1. After what operation, does your laptop fail? That may indicate the reason or failure part. If you were trying to update the BIOS, it is possibly caused by a corrupted BIOS.

  7. I have a pc compaq presario CQ71 fentere planted at the start (compaq)

    -Keyboard not detected

    I restored the bios [in the pile up] but nothing change

    -I changed the processor and RAM

  8. Thank You Very much mate, it 100% function on my HP G61-401SA.

    I just change name of bios version after extracted fom exe file.

    I Renamed from FD file to Bin, i send this file to a USB,pressed Win key + B for 5 seconds and wait till Laptop turned off while beeping.. after one minutes i turned on and HP logo displayed and windows Start

  9. Great work.

    question:
    I have a cq56 (AMD) laptop; BIOS functions perfectly, and that is the problem; this version of bios will not let me choose between native and non-native SATA support, which prevents XP from operating; will this method work in replacing currenct bios with an XP-friendly bios ? which bios image would I have to download, and from where ?

    1. Yes, you can update the BIOS to a lower version. I ever did this on my laptop.

      I am not sure which version supports Windows XP. You may try to find it on HP’s website.

      Remember to back up your critical data. Updating BIOS may fail.

      1. Followed the 3 different instructions on this blog; nothing happened, laptop did not beep; caps lock blinked; 10 seconds later machine re-started itself; as it stands, I can’t even demage this bios, much less modify or replace it.
        If I boot laptop using the USB_stick, none of these executables execute under DOS

  10. Hallo I have CQ60-220US, Can’t start with led power and wifi lighting, i have try to recovery bios with usb 4GB Fat sytem but no respon, no beep whats something wrong? or any my hardware thats problem? can help..

  12. Hi,
    I have an older HP Compaq NC6320 with corrupted bios; my laptop doesn’t boot at all, all I have is a blinking led. I’ve tried your method, but my laptop is still dead. Would you be so kind to give me detailed instructions?

  21. My friend , you are a god!!!!!!

    Really, thanx a lot , it worked just fine for me exactly as you described.

  22. i have hp pavilion dv6 2020ax. and i am facing the same problem of black screen after bios update failure. My laptop supports f13 bios version and it contained 3635F13.FD and i followed the above procedure but the problem still persists. Also i have tried different version but still not solved.So please help

    1. Hi.. I downloaded a bios for my presario c500 .. after extracting the .exe file the result was some files including .wph and .dll files But my presario won’t boot — flash disk not blinking= presario not reading it but the power led isn’t blinking what can I do

      1. You only need the .FD files. Is there any beeping? If the laptop keeps long beeping or beeping for more than 3 minutes, the recovery fails. In this case, I only suggest that you try another image file (.FD file) or (and) another USB flash disk.

      2. the .wph file is the bios update file needed.

        there are no .fd files for the bios of the c500 series
        hope this helps

  23. Dude you saved my laptop….
    In the past 7 days I tried all kind of methods and yours did the trick.
    Its important to understand that BIOS recovery can be done with USB flash drive lower than 2GB (FAT16 format is needed)

    Also , bios version that contains 2 *.FD files are actually two versions so you must try them separately.

    Thanks again
