[tso4ev]

Hi all I have a problem with missing lid screw from the factory I've contakt the pinebook per email the same day they told me that I need to wait they will contact their hardware devision.. And I'm still waithing for answer... I just need the specs for the screw to be able to order some it really bugs me...  the screw is at the bottom side of the lid (shorter one it has longer ones too same head I'm happy they are all in place) if someone knows the type or the name of it please to share with me
