I recently bought a Transcend M.2 SSD(http://www.amazon.com/Transcend-MTS400-Solid-State-TS128GMTS400/dp/B00KLTPUU0/ref=sr_1_4?ie=UTF8&qid=1415742846&sr=8-4&keywords=transcend+m.2+ssd) for my Lenovo Y410P. I have looked inside my laptop and confirmed that the m.2 port is there. But, the ssd did not come with a screw to screw it down to the motherboard, so I was wondering what size and where I can buy the screw.
