Lenovo Mylar Synaptics PCB 01YU300 — Large touchpad PCB replacement

Lenovo Mylar Synaptics PCB 01YU300 — Large touchpad PCB replacement is a direct electronic replacement component designed for Synaptics-compatible laptop touchpad assemblies. This large-format Mylar PCB restores the touchpad's sensing and signal functions when the original printed circuit board is damaged or malfunctioning. The component is intended for technicians and users performing component-level repairs on compatible Lenovo devices and must be installed into an existing touchpad housing and connector assembly.

Advantages

This replacement PCB provides a form-fit electrical substitute for the original Synaptics touchpad board, maintaining compatible trace layouts and connector alignment for an easier swap. Being a Mylar-based PCB, it is thin and flexible, which helps preserve the original mechanical fit inside the touchpad module. The board is intended to reproduce standard Synaptics signal behavior and enable restoration of cursor movement, multi-touch gestures and click detection when integrated with a compatible touchpad cover and ribbon cable.

Key specifications

• Form factor: large Mylar flexible PCB designed for Synaptics-compatible touchpad assemblies
• Function: capacitive touch sensing signal processing and connector interface
• Material: flexible Mylar substrate with printed conductive traces
• Compatibility: intended for installation in Lenovo touchpad modules using Synaptics electronics (verify mechanical and connector match before installation)
• Mounting: designed to be placed within existing touchpad housing and connected via ribbon cable/connector

How to use

Power off the laptop, disconnect the battery and ground yourself to avoid electrostatic discharge. Disassemble the laptop to access the touchpad assembly, remove the touchpad cover and detach the original PCB from the housing and ribbon cable. Install the replacement Mylar PCB in the same orientation as the original, secure it within the touchpad housing, and reconnect the ribbon cable and any grounding points. Reassemble the touchpad cover and laptop chassis, then power on and verify touchpad functionality and gesture response. If the device does not recognize the touchpad, recheck connector seating and alignment.

Recommendations

Before ordering, confirm mechanical dimensions and connector type to ensure this large Mylar PCB matches your touchpad module. Use ESD protection during handling and follow manufacturer service guides for disassembly and reassembly. If uncertain about compatibility, consult device-specific repair documentation or a trained technician.
