New Genuine Replacement Palmrest TouchPad with Keyboard for Lenovo

In this review of the New Genuine Replacement Palmrest TouchPad W/Keyboard for Lenovo Chromebook S345-14AST 81WX, the bottom line is simple: it is for Chromebook owners who need an authentic, direct-replacement upper chassis assembly to restore keyboard and touchpad functionality without compatibility guesswork. The reviewer finds the main reason to buy is its genuine OEM construction, which reduces fitment issues and preserves the original typing feel and trackpad response for the S345-14AST. This review focuses on practical fit, finish, and the tradeoffs compared with third-party kits.

Key Features

• Genuine replacement: Provides OEM construction for a precise fit and authentic feel that minimizes installation tweaks.
• Integrated palmrest and keyboard: Combines the upper case and keyboard in one assembly to simplify repairs and reduce alignment problems.
• Included touchpad: Restores full pointing-device functionality with the original touchpad layout for consistent gestures and palm rejection behavior.
• Model-specific compatibility: Designed for the Lenovo Chromebook S345-14AST model series to avoid guesswork about connector and screw locations.
• Quality finish: Matches the original external finish so the repaired laptop retains its factory appearance.

Who It's For

This replacement is best for owners of the Lenovo Chromebook S345-14AST who prefer an OEM part over a generic option, or for technicians who want a dependable, model-matched assembly to speed repairs. It suits users replacing damaged keys, a faulty touchpad, or a cracked palmrest and who expect original fit and tactile response.

Those who should look elsewhere include buyers with a different Chromebook model or those seeking a lower-cost, universal keyboard module; this part is specific to the S345-14AST and will not fit other chassis without modification.
