Lenovo y520 151BN M2 SSD not read in BIOS

Hi all,


The laptop model is  y520 151BN  / 80WK

I bought a cheap SSD called  -> Solid State Drive Intel E5400s, 120GB, M.2 


I installed it in the laptop however BIOS or Windows 10 is unable to see it .


Can you please let me know if this SSD is not compatible or what troubleshooting i could try ?

Hi Jones5


Welcome to the Community Forums.


You can try to check if the BIOS would recognize the M.2 SSD SATA Intel E5400s but most likely you need to get a PCIe M.2 SSD instead.


Checking on the specifications for the Y520 15IBN 80WK:

-2.5 inch, 7mm, SATA G3
-SSD, PCIE (M.2), 128 GB / 256 GB / 512 GB


Aside from those OEM SSD parts list on page 66 item14 of the hardware manual, parts lookup page also shows recommended M.2 SSD PCIe storage along with substitute here for Model type 80WK:


Part number 01FR500 Lenovo AM6671 M.2 2280 256GB PCIe LENSE20256GMSP34MEAT2TA SSD

Part number 01FR501 Lenovo AM6671 M.2 2280 512GB PCIe LENSE20512GMSP34MEAT2TA SSD

Part number 01FR511 Samsung PM981 512GB M.2 2280 PCIe MZVLB512HAJQ-000L2 SSD

Does an M.2 SSD support both SATA and PCIe?

No. An M.2 SSD will support either SATA or PCIe, but not both at the same time. In addition, system board sockets will be designated by manufacturers to support either SATA, PCIe or, in some cases, both. It is important to check your system’s manual to verify which technologies are supported. On some motherboards, there can even be sockets that support both and some limited to either SATA or PCIe only.

What would happen if I connect a PCIe M.2 SSD to an SATA-only M.2 port or vice versa?

If the host system does not support the PCIe protocol, the PCIe M.2 SSD will most likely not been seen by the BIOS and therefore would be incompatible with the system. Similarly, with an SATA M.2 SSD installed into a socket supporting PCIe M.2 SSDs only, the SATA M.2 SSD would not be usable.

Hope this helps answer your query.
