DELL Latitude E7240 HAL Sensor IO Board WITHOUT SIM CH2MC

Replacement HAL Sensor Board

This Dell Latitude E7240 HAL sensor IO board is a genuine OEM circuit board designed for the Latitude E7240 laptop without a SIM card slot. It serves as a direct replacement for a damaged or faulty daughter board. The part restores the hardware sensor functions managed by the HAL module. Installers should verify the laptop lacks the optional SIM reader before ordering.

CH2MC Part Number Match

The decisive specification is the Dell Part Number CH2MC which confirms exact fit for the Latitude E7240 model 7240 without SIM capability. Using a board with a different DPN risks connector misalignment or missing sensor functionality. No other model numbers or revisions are referenced for this component. Buyers who need the version with a SIM card slot cannot use this part.

Sustained Thermal Operation

As a passive sensor interface board, it contains no active cooling or power regulation components that would throttle under load. Its operation depends on the laptop's main thermal solution and power delivery remaining within specification. The circuit board handles continuous sensor polling and lid-switch signals without degradation. Builders needing a full motherboard replacement should look elsewhere.
