Replacement palmrest with touchpad, smart card reader, power button, speakers and spring latch for Precision 2400 laptops
This genuine Dell palmrest touchpad assembly is built for the Precision M2400 laptop. It restores the original typing surface, pointing device and integrated smart card reader in a single replacement part. The unit suits technicians or owners repairing a worn or damaged chassis on this specific mobile workstation model.
The decisive feature is the built-in contactless smart card reader, which is not present on every Precision M2400 palmrest variant. Verify that the original unit carried this security module before ordering, because the reader cannot be added later and an incompatible palmrest will leave the slot empty.
Installation follows the standard Precision M2400 disassembly routine: remove the keyboard, disconnect the old palmrest cables and swap the assembly. The part arrives with the touchpad, circuitry, power button, left and right speakers and spring latch already fitted, so no secondary components are required. A common error is forgetting to reconnect the smart card reader flex cable, which leaves the security function dead even though the touchpad works.
