Dry graphite lock lubricant

Are you sure you want to be spraying graphite around near a laptop?

Many such things are 'lubricated' on assembly with a damping fluid - a bit
like the spindles on controls - to give that "stirring treacle" feel (a
wonderful expression - found on this group)

A typical long chain molecule compound is this one:

Kilopoise.

Removing this can make the assembly feel very sloppy. Alternatively it may
have some sort of spring loaded expanding spindle to give some braking
effect.
