4. Professional Installation & Safety Guidance

CRITICAL: Lenovo motherboards and touch digitizers are extremely sensitive to electrical surges during maintenance. Failure to isolate power can result in a blown backlight fuse or motherboard failure.

1. Strict Power Isolation (Mandatory): Before starting the replacement, turn off the laptop. You MUST enter the BIOS (typically by pressing F1 or F12 during startup), navigate to the Config -> Power menu, and select "Disable Built-in Battery". The system will shut down automatically, cutting off all internal power.
2. 40-Pin Connector Precision: The 40-pin eDP/Touch connector handles high-speed video and digitizer data. Align and insert the connector perfectly straight. Secure the metal locking latch and apply fresh anti-static tape.
3. Hinge & Bezel Alignment: When installing the assembly, ensure the hinges are aligned correctly before tightening screws. Avoid applying excessive pressure to the corners of the glass to prevent "bruising" or digitizer damage.
4. Static Shielding: Always work on a grounded anti-static mat and use a wrist strap to protect the sensitive timing controller (T-CON) and touch IC on the back of the panel.
