The HP L77237-001 webcam shutter kit is a camera privacy cover spare part identified for the HP ProBook 445 G7 Notebook PC. It is intended for the display area around the built-in camera and is a separate component from the camera module.
When the cover needs replacement, HP’s service guide describes lifting it straight up and off the display. This makes the part relevant for restoring the camera-cover component during display service. The guide identifies the part number as L77237-001 and lists it as the camera privacy cover for this notebook model.
