How to open the Optical drive? (disc department on laptop)?

I have the G40-30 Lenovo laptop and I can't figure out how to open the disc thing. There's not a single button and it's not in the manual. Help!How to open the Optical drive disc department on laptop

View the drive in Computer, right click it and select eject. IF that is actually as drive and not just a blank plate.

It won't let me nject it

There's no Optical Drive, its just a cover if you want to in a future install it!

I have purchased a Lenovo Idea pad 310 and I can't open the optical drive. There's an option "This PC" (in fact I have a laptop) but no DVD drive is shown
