Lenovo Oem Logo Bmp 120x120 Patched Today
Download the official Lenovo BIOS update for your model (e.g., gjuj22us.exe). Extract it using 7-Zip. Look for a file like $0A82000.FL1 or BIOS.CAP.
Do not simply resize a high-res image to 120x120. That will introduce aliasing and moiré patterns. Instead:
Example of a valid file size: A 120x120 24-bit uncompressed BMP is exactly 43,254 bytes (header + pixel array). If yours differs, the BIOS will show a solid black screen or an error beep code.
Cause: Incorrect BMP byte order (BGR vs RGB). Convert your BMP to use BGR color space (standard for Windows BMP). Use ImageMagick:

For decades, PC enthusiasts and IT professionals have sought to personalize the boot experience of Lenovo laptops and desktops. Whether it’s a corporate branding requirement, a digital signage project, or simply the desire to replace the default "Lenovo" splash screen with a custom image, one specific file format has become the holy grail of low-level customization: the Lenovo OEM Logo BMP 120x120 patched.
This seemingly cryptic string of words—Lenovo, OEM, Logo, BMP, 120x120, Patched—represents a unique intersection of hardware BIOS limitations and user ingenuity. In this article, we will dissect every component of this keyword, explain why a "patched" version is necessary, provide step-by-step implementation guides, and explore the risks and rewards of modifying your system’s boot logo.
Cause: The patched BIOS corrupted the boot block. Fix: Download the official Lenovo BIOS update for your model (e
Lenovo’s legacy BIOS architecture (pre-2015) and even some modern UEFI implementations for "Quiet Boot" rely on a very specific file format:
If the image dimensions deviate by a single pixel, the BIOS will reject the file or display a garbled block. The 120x120 is non-negotiable for most Lenovo models using the Phoenix SecureCore or InsydeH2O BIOS.
The BIOS/UEFI environment is very primitive compared to a modern operating system. It cannot handle high-resolution JPEGs or PNGs, nor can it display images at the full resolution of the monitor immediately upon boot. Example of a valid file size: A 120x120
Here is where the magic happens. A stock or vanilla OEM logo BMP is digitally signed or checksummed by Lenovo. If you try to replace the default logo with any custom BMP—even one that perfectly adheres to the 120x120 BMP spec—the BIOS will detect a mismatch and either:
A "patched" version refers to a BIOS image (or a boot logo injection tool) where the digital signature verification has been bypassed, disabled, or replaced. Alternatively, it can refer to a pre-modified LOGO.BMP file that includes a fake checksum compatible with older Lenovo BIOS versions.
