DELL Latitude 5290 2-in-1 USH Daughter Board Power Button Home Button YFXHX

Genuine Dell OEM USH Daughter Board

This is a genuine Dell OEM USH daughter board that integrates the power button and Windows Home button for the Latitude 5290 2-in-1 tablet. It carries part number YFXHX and is intended as a direct replacement for the original component. The board matches the DAJ00 and LS-F371P identifiers found on the factory part. Buyers who need a version with fingerprint or NFC support cannot use this board.

Passive component with no active cooling

The daughter board is a passive circuit assembly that draws minimal power from the tablet's main system and generates negligible heat during normal operation. It requires no dedicated cooling, produces no audible noise and adds no measurable thermal load to the chassis. Installation simply restores the original power-button and Home-button functions without affecting system thermals.

Fits Latitude 5290 2-in-1 without biometric options

This USH board installs inside the Latitude 5290 2-in-1 tablet chassis and connects to the mainboard through the factory connector. It is compatible only with units that lack the optional fingerprint reader and NFC reader, so verifying the existing hardware before purchase is essential. The part frees the user from a non-functional power or Home button while leaving all other tablet features unchanged.
