is it true that y510p short of stock currently?? i facing problem that the seller keep delaying to deliver the new replacement to me?
last month i bought y510p but i found out it was demo unit. so i request for new replacement unit. the seller agreed but then when i asked when can get the new replacement he keep saying new stock take long time to get. it's one n half month already but i still not yet get the new replacement. any solution to this situation?

Some ppl with the same problem (no M.2 NGFF connector installed on the motherboard), have suggested installing a connector on their own.
Here's the link.

I've asked Lenovo again about this & still haven't gotten a reply yet either. Anyone here tried installing the connector on their own?

For SLI model, u can install faster 2.5" SATA SSD with OS/programs in HDD bay for faster response time, then
- use slower HDD as external drive or
- replace DVDrom with HDD in 9.5mm compatible caddy bay as mentioned earlier, use swappable GT750m or HDD according to ur needs.

Not recommend to use faster SSD as external with slower usb3.0 port.
