  • M.2 Putty pad kit

Important
Gap pad/putty pad replacement guidelines

  • To identify the gap pad/putty pad location and orientation, see Gap pad/Putty pad identification and location.

  • Before replacing the gap pad/putty pad, gently clean the interface plate or the hardware surface with an alcohol cleaning pad.

  • Hold the gap pad/putty pad carefully to avoid deformation. Make sure no screw hole or opening is blocked by the gap pad/putty pad material.
