Disable oscillating light on MacBook Pro when in sleep mode This is not the same question as Can I disable the lighted Apple logo on the back of my MacBook Pro?

When I shut the lid of my macbook pro, it goes into sleep mode.  When it is in sleep mode, there is a small oscillating white light on the front of it.



That small pill-capsule-like shape on the long metal strip glows forever on end when in sleep mode.  Is there any way to disable this while keeping the computer in sleep mode?
Yes.

Put a piece of cardboard in front.

I have tested and approved this solution.

As far as I know, this is the only non-destructive solution.
