Once you have your OEMLogo.bmp file, you need to place it in the correct folder.
The story of the is a nostalgic trip through the golden era of PC customization, where a tiny 120x120 pixel BMP file served as the digital fingerprint of a computer's identity. The Genesis of the Digital Badge
Today, while modern UEFI BIOS logos have largely replaced the static BMP file for startup branding, the oemlogo.bmp remains a beloved artifact for retro-tech fans. It represents a time when the identity of a laptop wasn't just on the lid, but deeply embedded within the software itself—a small, square tribute to the hardware under the hood.

For enthusiasts and system builders, managing this logo was a rite of passage. To ensure the logo appeared correctly in the "System" menu, it had to follow strict technical constraints: : Exactly 120x120 pixels . Format : Standard Windows Bitmap ( BMP ).
If you need to create or edit a Lenovo OEM logo in BMP format, ensure that you use a graphics editing software that supports BMP files, such as Adobe Photoshop or GIMP. When designing or editing the logo, keep in mind the following: Once you have your OEMLogo
: While often 16-bit to save space and ensure compatibility, users frequently upgraded them to 24-bit for better clarity on newer displays. A Symbol of Professionalism
To complete the OEM branding, you can add a text file. It represents a time when the identity of
During the mid-2000s, seeing that specific blue or red Lenovo logo on a 120x120 canvas meant you were likely using a "business-grade" machine. For technicians deploying Windows 10, the tradition continued in a slightly different form. Even as high-resolution displays became the norm, the requirement for a small, 120px x 120px BMP logo remained a core part of the , ensuring the brand was visible regardless of the OS version. The Legacy of Customization
Lenovo’s firmware (BIOS/UEFI) and the Windows System Properties panel ( sysdm.cpl ) rely on legacy code that dates back to the Windows XP/Vista era. The standard specification for the OEM logo in Windows is:
If you have ever tried to customize the boot screen or system properties logo on a Lenovo laptop or desktop (ThinkPad, IdeaCentre, Legion, etc.), you have probably run into a very specific and frustrating requirement: the image must be a 120x120 BMP file .
The technical requirements for a Lenovo OEM boot logo are strict. To ensure compatibility with the UEFI firmware and Windows bootloader, the image must be a standard BMP (Bitmap) format. Specifically, it should be a 24-bit or 32-bit depth file. While 120x120 pixels is the legacy standard for small-scale branding, modern high-resolution displays sometimes scale this image, making pixel-perfect dimensions critical to avoid blurring or distortion during the handoff from BIOS to the Windows loading circle.
