3. Comprehensive Compatibility Guide

Verified Machine Types:

This assembly is the certified factory replacement for:

• ThinkPad X9 15 (High-end configuration with OLED Touch).
• FRU Cross-Reference: Always verify your original FRU (5D11Q29378) to ensure 100% cable and mounting synchronization.

Critical Compatibility Note:

• OLED Motherboard Sync: This part is strictly intended for models that originally shipped with the 2.8K OLED panel. Due to significantly different voltage requirements, it is not compatible with motherboards designed for IPS/FHD panels unless the eDP cable and BIOS firmware are specifically updated.

5. Professional Installation & Safety Guidance

CRITICAL: ThinkPad X-Series motherboards and OLED power rails are extremely sensitive to residual electrical current. Improper handling will result in permanent motherboard failure.

1. Strict Power Isolation (Mandatory): Before starting the replacement, you MUST enter the BIOS, navigate to Config > Power, and select "Disable Built-in Battery". The system will shut down. This is the only way to electronically isolate the motherboard.
2. Cable Precision: The 40-pin high-bandwidth eDP connector must be inserted perfectly straight. Secure the metal locking latch and apply fresh anti-static tape to prevent signal flickering or "ghost touch" issues.
3. Static Shielding: Always work on a grounded anti-static mat. The OLED driver ICs and the T-CON board are sensitive to ESD (Electrostatic Discharge).
4. No-Pressure Handling: OLED glass is significantly thinner than traditional LCDs. Handle the assembly strictly by the edges; never apply pressure to the center of the display during installation.
