Super User Core Functionality System Identification : Programs the Serial Number Product Number (SKU) Notebook Model directly into the BIOS/DMI. Board Configuration : Sets the MAC Address
, which are essential for software licensing and hardware identification. Troubleshooting
: Fixes startup errors like "Missing system board information" (OOA) or "Product Information Not Valid" that appear if a motherboard is unbranded. HP Support Community Key Specifications & Tools Description HPBQ138.EXE
The specific executable file for running the DMIFIT utility in a DOS environment. Environment Runs under ; it cannot be executed directly within standard Windows. Deployment
Typically requires a bootable USB drive created with tools like Applicability Older models (2007–2014) often use , while newer commercial notebooks after 2011 use Important Considerations Missing system board information on startup.(OOA)
This feature would also require a "Tech ID Authentication" sub-module. Since HPBQ138.EXE has the capability to alter hardware identities (which can be used to bypass anti-theft protections), the feature should enforce that only authenticated technicians with valid HP Partner credentials can execute the "Write" command.
The DMIFIT tool and its executable component, HPBQ138.EXE, are specialized software utilities used by HP technicians to "tattoo" or program system board information into an HP laptop's BIOS. This process is most common after a motherboard replacement, where the new board often lacks the original serial number, model name, or SKU, causing the system to show a "Product Information Not Valid" error on boot. What is the DMIFIT Tool?
DMIFIT stands for DMI (Desktop Management Interface) Firmware Interface Tool. It is a DOS-based utility designed to communicate directly with the system's firmware.
The Goal: To ensure the hardware's internal identity matches the physical stickers on the chassis.
Key Functions: It allows you to write or rewrite the Serial Number, SKU, UUID, and PCID.
Evolution: Introduced around 2009, it replaced older tools like HPSetCfg and BrandIT to provide a unified package for both consumer and commercial notebooks. Understanding HPBQ138.EXE
HPBQ138.EXE is the specific executable file within the DMI toolkit used for legacy and older HP platforms (typically those manufactured between 2007 and 2014). DMIFIT tool and HPBQ138.EXE
Environment: It must be run in a bootable DOS environment (like a USB drive created with Rufus).
Legacy Support: While modern HP systems use the Windows DMI Firmware Interface Tool (WNDMIFIT) or the HP BIOS Configuration Utility (BCU), HPBQ138.EXE remains a primary resource for older ProBooks and EliteBooks. How to Use the Tool (Step-by-Step)
Caution: Modifying BIOS information is risky. If entered incorrectly, it can cause licensing issues with Windows or make the system difficult to service.
Preparation: Locate the system information on the sticker (usually found under the battery or on the bottom of the laptop).
Create Bootable Media: Use a tool like Rufus to create a bootable MS-DOS or FreeDOS USB drive.
Copy Files: Place HPBQ138.EXE and its supporting files onto the root of the USB drive.
Boot to USB: Restart the laptop and tap F9 or Esc to enter the boot menu, then select your USB drive.
Run Command: At the DOS prompt, type HPBQ138.EXE and press Enter.
Input Data: Follow the on-screen prompts to enter the following: Serial Number: Found as S/N. Notebook Model: e.g., "HP ProBook 450 G2".
SKU Number: Also known as the Product Number (e.g., WA985UA#ABA).
PCID: A long string of numbers often found under the battery.
Save and Exit: Once the fields are filled, save the changes and reboot. When to Use These Tools DMIFIT tool (specifically HPBQ138
How can I fix the boot process on my HP laptop? - Super User
Cause: The executable does not recognize your DMI interface version.
Fix: Find a newer (or older) DMIFIT version. Look for SP numbers like SP38833.exe, SP41222.exe, etc.
HPBQ138.EXE is a vendor-supplied executable associated with Hewlett-Packard (HP) systems. It commonly appears as part of HP’s firmware or diagnostics utilities and may be used to update BIOS/firmware, set DMI/SMBIOS fields, or perform system-specific configuration tasks. On HP business desktops and laptops, such utilities often provide capabilities to program asset tags, service tags, or other system identifiers used by inventory and support systems.
Typical context and precautions:
If you want a concise how-to (examples of common DMIFIT commands, or safe steps to run HPBQ138.EXE), tell me your exact goal (inventory/reporting vs. modifying DMI fields vs. firmware update) and the Windows version and HP model; I will provide a step‑by‑step guide.

In the world of IT hardware repair, the story of the DMIFIT tool HPBQ138.EXE
is one of mystery, precision, and "tattooing." These tools are essentially the digital branding irons for HP motherboards. The Purpose: "Tattooing" the Motherboard
When an HP laptop's motherboard is replaced, the new board usually arrives "blank"—it doesn't know its own serial number, product ID, or model name. This causes a "Product Information Not Valid" error on every boot.
(DMI Firmware Interface Tool) is the overarching utility package used to fix this. HPBQ138.EXE
is the specific executable file, often running in a DOS environment, that allows a technician to "tattoo" (write) the correct identifying data into the system board's EEPROM. The Process: A Technician's Journey
The "story" usually follows a specific sequence of high-stakes steps: Security Note This feature would also require a
This guide explains how to use DMIFIT (specifically the HPBQ138.EXE utility) to resolve the "Product Information Not Valid" error on HP laptops, typically encountered after a motherboard replacement. Prerequisites A USB flash drive. HPBQ138.EXE (the DOS-based DMI tool).
System information from the laptop’s stickers (usually under the battery or on the bottom cover): Serial Number (S/N) Product Number (SKU) PCID (Configuration ID) System Board CT Number (if available) Step 1: Create a Bootable USB Drive Download a tool like Rufus to create a bootable DOS drive.
Set the partition scheme to MBR and the target system to BIOS (or UEFI-CSM). Choose FreeDOS or MS-DOS as the boot selection.
Once created, copy the HPBQ138.EXE file directly onto the root of the USB drive. Step 2: Boot into the Utility Insert the USB into the target HP laptop. Power on and immediately tap F10 to enter BIOS.
Ensure Legacy Support is enabled and Secure Boot is disabled. Save and exit, then tap F9 to open the Boot Menu.
Select your USB drive. Once the DOS prompt (e.g., C:\>) appears, type HPBQ138.exe and press Enter. Step 3: Update System Information
The utility will present a numbered menu. Enter the data exactly as found on your hardware stickers: 0. Serial Number: Enter the S/N.
1. Notebook Model: Enter the official model name (e.g., EliteBook 840).
3. UUID Number: Select "1" to generate a new UUID if it is missing.
4. SKU Number: This is your Product Number (e.g., WA985UA#ABA).
7. PCID: Enter the 25-character configuration ID found on the laptop's sticker. Step 4: Save and Restart
