I ordered a P50 and plan to install a separately ordered M2 SSD but am confused by the variety of options here. There are multiple types of M2 connectors and sizes out in the market and unfortunately I could not find exacts specs on the M2 in the P50/P70. What do the 2 bays offer? I was planning an m2 850 EVO (N5E500BW 2280 size which comes with B&M key connector). Will this work? According to cruical the MX200 which has the same size and connector is compatible. On the other hand I have seen reports by people putting in the samsung 950 pro which comes with an M-Key connector. Does the socket support both?

M.2 drives come in several flavors:
- NVMe (PCIe)
- AHCI (PCIe)
The M.2 850 EVO drive you're referencing is a SATA M.2 drive. This should be supported in either of the M.2 slots on P50.
Each of those slots is capable of supporting M.2 PCIe drives (NVMe or AHCI) as well. Note that AHCI drives should be supported natively by win7/8.1/10, but NVMe drives will require a driver to work with win7 (support for NVMe is native to win8.1 and win10).
You'll need one of the M.2 trays for each M.2 drive (regardless of type) you intend to install in the P50. Note that typically M.2 drives will install with the components facing down in the carrier. There should also be a thermal pad on the bottom of the carrier.
There is an easy way to distinguish whether a M.2 drive is SATA or PCIe based. SATA M.2 drives have two notches in the edge connector, while PCIe drives only have one.
Here's a pic that should help:

I have bought a 850 Evo which is SATA connector.
After installation on my thinkpad p50, neither BIOS nor disk management detects this new drive.
I tried both slots, but neither or them works.
There are a lot of people facing the same problems on Internet, but no one knows how to fix this.
Do you know how to solve this?
Looking forward your response,

When you shutdown your P50/P70 to add/remove hardware, how are you doing it?
Win10 "shutdown" is not a real shutdown, it's more like a hibernate. BIOS gets confused if you are adding/removing hardware in this state. Most of POST gets skipped when turning on the PC from this state, so hardware changes aren't noticed.
To do a real shutdown, press and hold Shift key while you choose shutdown option in Win10.
The 2.5" SSD problem happens when you don't do a real shutdown.
If you do a real shutdown before adding the 2.5" SSD, it works fine.
To make Win10 always do a real shutdown (without holding down Shift key):
Notice the power LED behavior before and after this change, when doing a shutdown. with fast startup, the LED blinks during shutdown (like a hibernate). without fast startup, the system just turns off right away (like a real shutdown).
Hope that this solves your issue. Please post back on results.

What harrisb said is the exact reason and solution. I have helped others for the exact same issue who were not realizing that Win 10 is not doing a proper shutdown by default.

Not in my case. Already have / had fast bood disabled.
I'm going to try the 850 m.2 in a home machine tonight to see if maybe it was DOA from Samsung.
I am getting:
2100: Detection error on SSD1 (m2) or
2104: Detection error on Storage Device2 (m.2)
Depending on which m.2 slot I put the SSD in.

I was getting the errors also. But I am now running a Samsug 850 M.2 with no issues, after having to RMA my 850.
The problem is Lenovo's drive caddy and internal connector allow for the M.2 drive to be installed upside down. Do it wrong the first time and it smokes the 850 M.2 iteself. Ask me how I know.
I have successfully installed many M.2 drives in desktops and other laptops without issue. First try on a P50 resulted in failure.
Moral of the story...BE EXTREMEMLY CAREFUL WITH ORRIENTATION WHEN INSTALLING M.2 in a P50/P70
