The Lenovo 5CB0U26489 Upper Case Assembly (ASM USB81QB) with Keyboard and Touchpad is a genuine replacement palmrest unit designed for Lenovo Chromebook 100e 2nd Gen (81QB series) and compatible models. It includes the full upper chassis assembly, integrated keyboard, and built-in touchpad, making it a complete solution for repairing damaged or non-functional laptop input systems.
This part is commonly used for replacing worn-out keyboards, broken palmrests, or faulty touchpad assemblies. Since the keyboard and touchpad are integrated into the upper case, replacement is done as a full unit rather than individual components.
