Genuine HAL sensor board for Latitude 7250
This Dell OEM circuit board provides the Hall-effect sensor and I/O functions for Latitude E7250 laptops that were built without a SIM card reader. It is a direct replacement for the original WKK6T daughter board used in those specific chassis.
Replaces a missing or faulty sensor board
If the laptop no longer detects lid position or the I/O functions tied to this board have failed, swapping in this genuine part restores the original behaviour. The upgrade is only worthwhile when the exact Latitude E7250 configuration matches the non-SIM variant.
Straightforward daughter-board swap
Installation requires opening the chassis, disconnecting the old board and seating the new one in the same connector. Common issues arise when the part is fitted to a SIM-equipped model or when flex cables are not fully seated, causing intermittent sensor errors.

Questions about this item
Does the WKK6T HAL sensor board fit inside the Dell Latitude E7250 chassis without a SIM card slot?
Yes, this genuine Dell OEM board is built for the Latitude E7250 without the optional SIM card reader and matches the original daughter-board footprint.
What is the installation sequence for the HAL sensor board, and which step is most often missed?
Remove the battery, detach the palm-rest assembly, unplug the old board's flex cable, seat the WKK6T board, reconnect the flex cable, then reassemble; the step most often missed is disconnecting the battery first.
When will the HAL sensor board need replacement?
Replace the board if the laptop no longer detects lid open or close events, causing the screen to stay on or fail to wake, which indicates the Hall-effect sensor has failed.
