HP Pavilion model 13-bb050 did not start because something wrong with the bios

[Paqueton]

I need help to get the BIOS firmware for the HP pavilion model 13-bb050 because 

the HP web page there are not information, looks like (no sure) because my laptop is out of warranty this information is not available.

Or there is any other web page where the information is...

I really apreciate all the help somebody could provide me

Thanks

@Paqueton,

Welcome to our HP Community forum!

Please explain what the issue is, because the driver link for your laptop shows the latest BIOS update (F.49) as well as nine previous BIOS versions.

Kind Regards,

Thanks NonSequitur777 for the reply,

problem is that laptop is not working, it has a black screen

I made process to try to reflash BIOS firmware, I got from official HP page web, but it does not work

I wrote into the BIOS chip, but looks like firmware is not complete some information is missing, I asked ChatGPT to figured out a solution, the suggestion is to get a clean dump or tested dump to correct the problem

I have a pavilion 13-bb050 model, board is 087C with 16MB size, BIOS firmware I got is sp158905.exe

Hopefully you can help me to solve it

Regards

@Paqueton1,

I believe that the issue you are experiencing is very common when attempting to program a BIOS chip manually.

Why the HP .exe File Caused a Black Screen:

The firmware file extracted from sp158905.exe is not a raw, ready-to-flash binary file. HP updates downloaded from the website are highly compressed, encrypted, or include extra header padding (often making the file slightly larger than 16MB).

If you write that extracted file directly to your 16MB chip with a hardware programmer, the entire memory map shifts out of place. The motherboard cannot read it, which results in the bricked, black screen you are seeing now.

How to Fix It aka The Correct Process:

To fix this, you need a complete 16MB binary (.bin) dump file specifically prepared for a hardware programmer.

Do you still have a backup copy of your original, un-flashed 16MB dump?

• If you HAVE the original backup: Do not delete it! That file contains your laptop's unique identifiers, including your Windows Digital Product Key, Serial Number, UUID, and Feature Bytes. To fix the laptop, you must use a free Hex Editor (like HxD) to open both your original dump and the HP file, locate the exact 16MB block of actual code, and merge them. Alternatively, you can use Intel FIT (Flash Image Tool) to inject the new HP BIOS region while cleaning the Intel ME (Management Engine) region.
• If you DO NOT have the original backup: The official HP website alone cannot help you anymore. You will need to download a "tested dump" pre-extracted by a technician from a motherboard repair community such as Badcaps Forums (Bios Requests section) or Vinafix.

Note: If you use a third-party dump from a forum, your laptop will boot up, but you will likely see a "Missing System Information" error on startup. You will eventually need to use the HP DMI Tool to manually type your serial number and SKU back into the board.

Next Steps:

Do you have your original backup file saved on your computer, or are you starting completely from scratch? If you have the original file, let me know, and I can try to help you figure out how to clean it or point you toward the right repair communities to get a pre-cleared file for board 087C.

Guidelines Before You Post to the Badcaps Forum:

To get a fast, working response from the Badcaps forum technicians, include these specific details in your post:

• The Motherboard Model: 087C, but you should also look at the physical motherboard for a printed part number (e.g., something like DAG7BMB16I0).
• The Original Dump: You must attach your original corrupted 16MB .bin file to the forum post*. Forum volunteers need this original file to extract the laptop's unique Windows Key and DMI serial data to merge into the clean version.
• The Official File Link: Provide the exact link or the name of the file you downloaded from HP

* If it is the case that you completely overwrote or deleted your original backup file, the laptop can still be fixed, but the software process changes slightly.

Instead of repairing your specific file, you will need to boot the machine using a generic, third-party version. If you do not have the backup, you should take these steps:

1. Request a "Generic" Tested Dump:

You must still make a post on the Badcaps BIOS Requests Forum. However, instead of asking for a file repair, you should explicitly state, quote: "I lost my original backup file. I need a clean, working 16MB generic dump for HP Pavilion 13-bb, board model 087C".

• Another technician or forum volunteer who has serviced the exact same motherboard model will hopefully share a copy of their own successful 16MB backup.

2. Prepare for the "Missing System Information" Screen:

When you write this generic file to your chip and turn on the laptop, the laptop will boot up and work, but the screen will display a red or white warning text before loading Windows.

The motherboard will display errors like:

• “Product Information Not Valid”
• “System Board OOA / Missing System Information”

This happens because the new BIOS chip does not know the machine's individual physical identity. It will also lack the original, factory-embedded Windows digital license key.

3. Re-inject the Laptop's Data (DMI Tattooing) :

To remove the startup errors and make the laptop completely normal again, you will need to manually program the original identifiers back into the new BIOS.

1. Flip the laptop over and look at the tiny text sticker on the bottom case (or look inside the battery bay). You need to write down the Serial Number (S/N), Product ID (SKU), and Feature Byte string.
2. Download a tool widely available on repair forums called the HP DMI Tool (also known as HPSETCFG or wndmifit).
3. Run this utility from a bootable USB drive or directly inside Windows. The tool provides empty fields where you can type the physical serial number and product ID directly back into the motherboard's memory banks. Once saved, the startup errors disappear permanently.

The loss of the original file adds one extra step at the very end, but it is still entirely salvageable and vastly preferable to purchasing an overpriced replacement motherboard.

I will work on it

Thanks NonSequitur777

I checked that I have the original BIOS file, also checked again the one I got from HP web site and search for 087C with the following results

Laptop file             087C search   line 00FDBFA0    result   24 42 49 44  30 38 37 43   BID087C

web page file       087C search   line 00FFBFA0     result  24 42 49 44  30 38 37 43   BID087C

I hope this information could be usefull
