For users looking to customize their Lenovo devices with a professional touch, creating a high-quality 120x120 pixel BMP logo is essential for branding Windows System properties or BIOS splash screens. Technical Specifications
To ensure compatibility and high visual fidelity on Lenovo systems, your logo must adhere to these technical standards: Dimensions: Exactly Format: Windows Bitmap (.bmp).
Color Depth: 32-bit color is standard for Windows OEM information, though some older BIOS versions may require 16-bit or 24-bit depths.
File Size: Keep the file size under 30KB for BIOS integration to ensure it loads during the boot sequence. Visual Branding Guidelines
Lenovo has strict identity standards to maintain a professional look:
Clear Space: Always maintain a "clear space" around the logo equal to the width of the letter 'L' to prevent it from appearing cluttered against other elements.
Logo Integrity: Do not distort, rotate, or change the containing shape of the logo.
Color Accuracy: The official Lenovo "Rainbow Red" is hex code #E60012.
Readability: For digital applications, the logo should typically not be reproduced at widths smaller than 100px to ensure the text remains legible. Deployment Methods Lenovo OEMLOGO.BMP image request - Thinkpads Forum
For a high-quality Lenovo OEM logo in the requested BMP format, follow the specifications and installation steps below to ensure compatibility with Windows OEM information or BIOS splash screens. 1. File Specifications
To maintain "high quality" while meeting technical constraints (especially for BIOS), ensure your final file adheres to these standard Lenovo requirements Windows Bitmap ( Dimensions: pixels (User requested). Color Depth:
24-bit (Standard) or 4-bit (16 colors) for older BIOS compatibility. File Size: Typically must be under for BIOS injection. 2. Sourcing the High-Quality Logo Since standard logo assets are typically widescreen, a lenovo oem logo bmp 120x120 high quality

How to Create and Apply a High-Quality 120x120 Lenovo OEM Logo BMP
If you are a PC builder, an IT professional, or a modding enthusiast, you know that the "OEM Logo" is that splash of branding that appears during the BIOS boot sequence or within the Windows System Properties page. For Lenovo hardware, using a high-quality 120x120 BMP file is the standard for maintaining a professional, factory-fresh look.
In this guide, we will cover why the 120x120 BMP format is essential and how to implement it correctly. Why the 120x120 BMP Format?
Modern UEFI BIOS and Windows environments have specific requirements for OEM branding. While screens are now 4K and beyond, the legacy hooks for system logos often rely on a specific bitmap (BMP) standard:
Dimensions (120x120): This is the "sweet spot" for Windows System Information windows. If the image is larger, it may be cropped; if it is smaller, it may appear pixelated when scaled.
File Format (BMP): Unlike JPEGs, BMP files are uncompressed. This prevents "artifacting" around the edges of the Lenovo text, ensuring the logo looks crisp against a white or grey background.
Bit Depth: For maximum compatibility across Lenovo ThinkPad, IdeaPad, and Legion series, a 24-bit or 32-bit BMP is recommended to support a full range of colors and smooth gradients. Step 1: Creating a High-Quality Lenovo Logo For users looking to customize their Lenovo devices
To get a "High Quality" result, you shouldn't just grab a tiny thumbnail from a Google search.
Source a Vector: Start with a high-resolution PNG or SVG of the Lenovo logo (the modern "Lenovo" rectangle or the classic "ThinkPad" logo).
Use Professional Software: Open the file in Photoshop, GIMP, or even a high-end web-based editor.
Resize with Care: Set your canvas to exactly 120x120 pixels. Use "Bicubic Sharper" resampling when shrinking the logo to maintain the clarity of the typography.
Save as BMP: When exporting, select Windows Bitmap (BMP). Ensure the color depth is set to 24-bit. Step 2: Applying the Logo to Windows
Once you have your oemlogo.bmp, you need to tell Windows to display it.
Move the File: Place your 120x120 BMP into C:\Windows\System32\. (Note: You may need admin permissions). Registry Edit: Press Win + R, type regedit, and hit Enter.
Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\OEMInformation
Look for a String Value named Logo. If it’s not there, create it. Set its value to the path: C:\Windows\System32\oemlogo.bmp
Verify: Open Settings > System > About. You should now see your high-quality Lenovo logo displayed prominently. Step 3: Flashing to BIOS (Advanced Users Only)
For those who want the Lenovo logo to appear the moment the power button is pressed, you must modify the BIOS/UEFI. Download the latest BIOS update for your Lenovo
Lenovo Logo Tools: Lenovo often provides a "Logo.bat" or "WinLogo" utility within their BIOS update packages.
The Constraint: BIOS logos often have strict file size limits (usually under 30KB or 60KB). Even at 120x120, ensure your BMP isn't "bloated" with unnecessary metadata, or the flash utility might reject it.

By following these specs, you ensure that your Lenovo system looks as professional on the inside as it does on the outside. Whether you are restoring a refurbished ThinkPad or personalizing a new Legion rig, a high-quality 120x120 BMP is the professional standard.
Does replacing the Lenovo OEM logo void your warranty? In the US and EU, not typically—unless you brick the device. The Magnuson-Moss Warranty Act (US) requires the manufacturer to prove your modification caused the fault. However, Lenovo’s warranty explicitly excludes "damage from unauthorized BIOS modifications." Tread carefully.

Tools like UEFITool and Universal BIOS Backup Toolkit allow you to extract the existing logo RAW from your BIOS image. The extracted file is almost always already in the correct 120x120 BMP format.
ImageMagick (command line):
convert lenovo_logo.png -resize 120x120 -background white -flatten BMP3:lenovo_logo.bmp
