Genuine Dell Palmrest Keyboard Assembly
This genuine Dell OEM palmrest and keyboard assembly fits Inspiron 11 3157 and 3158 laptops. It replaces a worn or damaged upper case section with an original factory part. The assembly includes the keyboard and palmrest frame only.
No Touchpad Module Included
The package does not contain the touchpad sensor module, so the existing module must be transferred from the old palmrest. Installation requires disassembly of the laptop chassis to swap the upper case. Compatibility is limited to the two listed Inspiron 11 models.
Verify Exact Model Before Ordering
Confirm the laptop is an Inspiron 11 3157 or 3158, as other 11-inch Dell models use different part numbers. Check that the current touchpad module is functional and reusable. Buyers who need a complete upper case with touchpad included should look for a different assembly.
