Replacement palmrest with integrated touchpad for Dell Precision M90 laptops in gray
This genuine Dell palmrest and touchpad assembly is designed specifically for the Precision M90 mobile workstation. It restores the original input surface and structural integrity for technicians or owners servicing this model. The grey finish matches the factory chassis colour exactly.
As a passive mechanical component, this assembly draws no electrical power and generates no heat or acoustic noise during operation. It adds negligible thermal mass to the chassis and does not affect the laptop's cooling performance or battery runtime in any measurable way.
The package contains only the palmrest and touchpad hardware; no drivers, utilities, or mounting screws are included. Installation relies on existing fasteners and the operating system's native pointing-device support, so no additional software configuration is required.

Align the palmrest screw holes with the chassis standoffs, connect the touchpad ribbon cable to the motherboard header, then secure all screws in a cross pattern to avoid warping the frame.
The touchpad sensor and click buttons wear first; the surrounding palmrest plastic rarely fails unless cracked by impact.
Extended sessions can cause the touchpad controller to overheat, leading to cursor lag or temporary loss of tracking until the assembly cools.
