DELL Chromebook 11 3120 Palmrest Keyboard Assembly No SIM RM8HM

SKU CH-MZPM-FVG8X

Replacement palmrest assembly with integrated touchpad and keyboard for the Dell Chromebook 11 3120, excluding the SIM card door

  • Genuine Dell OEM assembly for Chromebook 11 (3120) 2015
  • Complete palmrest with touchpad and keyboard included
  • Part number RM8HM matches original Dell specification
  • No SIM door — fits non-SIM models only
  • Ready to install replacement for damaged palmrest

Genuine Dell OEM replacement assembly

This genuine Dell OEM palmrest and keyboard assembly is built for the Chromebook 11 3120 from early 2015. It combines the palmrest, touchpad, mouse-button circuit board and keyboard in one unit. The part carries Dell part number RM8HM and matches the original factory specification. Buyers needing a SIM-card door should look elsewhere, as this assembly omits that component.

Passive component with no power draw

The assembly contains no fans, motors or active electronics beyond the touchpad and keyboard circuits. It draws no measurable power and adds no audible noise to the system. Thermal behaviour is unchanged because the part simply replaces the original chassis section. Installation requires only standard hand tools and the existing fasteners on the 3120 chassis.

Fits Chromebook 11 3120 without SIM support

Direct compatibility is limited to the Chromebook 11 3120 2015 model without a SIM-card reader. The missing SIM door means the assembly will not suit 3120 units equipped with mobile broadband. No additional cables, brackets or adhesives are required beyond what the laptop already provides. The integrated keyboard and touchpad restore full input function once secured.

Questions about this item

How do I install the palmrest and keyboard assembly on my Chromebook 11 3120, and what step is often missed?

Remove the bottom case screws, disconnect the battery, then detach the old palmrest cables; the step often missed is reconnecting the touchpad ribbon cable under the keyboard before securing the new assembly.

What maintenance or replacement will this palmrest assembly need later?

The keyboard and touchpad circuit board are integrated; if keys fail or the pointer drifts, the whole assembly must be replaced rather than serviced individually.

What limit appears first under sustained typing on this 3120 palmrest?

The plastic keyboard deck can flex during long sessions, causing key travel to feel inconsistent before any electronic fault develops.
