HP M29534-001 Solid-State Drive/Memory Module Thermal Pad Kit is a service replacement for the thermal pad material used with solid-state drive and memory components. The HP service manual identifies it as a kit containing replacement thermal material.
The manual lists M29534-001 in the parts catalog for the HP ZBook Fury 17 G7. It also notes that a thermal pad sits on the solid-state drive cover and should be inspected when that cover is removed. This makes the kit relevant when servicing the documented SSD thermal-pad arrangement.
This is a specific HP spare part for SSD and memory thermal-pad service; the manual does not provide dimensions or describe additional kit contents.
