## Long description

Lenovo replacement PCB board with Synaptics touch controller (model: lar + Synaptics PCB, GS) is a component-level printed circuit board intended for repair and replacement of touchpad or input subsystem electronics in compatible Lenovo devices.

How to use
Installation should be performed by a qualified technician familiar with laptop disassembly and ESD-safe handling.

After reassembly, boot the system and verify touchpad operation and driver recognition.
