Hi,
On my Asus X200M notebook, there's this black colored sheet covering the motherboard.
I am curious what is the purpose of placing such a sheet on top of motherboard?
Is is some sort of insulator. It's black and is not transparent.
See a photo.
Thanks & regards.
R Gangal.

Yep!

An insulator to prevent electrical shorts/arcing/fire retardant when dropped, stomped on, or ran over by anything. Maybe, causes for delayed traveling or trips to other places.
