Thinkpad T14 WWAN SSD

2021-09-02, 18:44 PM

Hi there,

 

I've seen some discussion around, about Thinkpads which supports a SSD into the WWAN port. I wanted to try this in my Thinkpad too, without success.

 

The M.2 SSD fits perfect in the WWAN module. The Thinkpad boots, and it even says: "Configuration changed - restart the system". But it doesn't show up in Windows (not in device manager, not in disk manager). Also when putting in a Windows install USB stick it's not showing up.

 

Is it just not possible for my Thinkpad, or is there a bios setting that I need to change?

Or is it maybe not the right SSD (type)?

 

I have a Thinkpad 20UD0013MH, the SSD I bought for it is the Transcend 430S (2242 size). I've also tried some 2280 M.2 I had laying around (for testing), they didn't work too.

 

Any help? Thanks :)

Hello Marvintje123!


Welcome to community forums

 


If the part number or FRU number is listed as compatible on the link below then it should work: https://pcsupport.lenovo.com/ph/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t14-type-20ud-20ue/20ud/20ud0013mh/parts/display/model

 

Filter the commodity type to a solid-state drive.

If it's not, then we can not guarantee its compatibility


Regards

 


Jwes_Lenovo

@Jwes_Lenovo So it should work in de WWAN port if it is listed there?

 

@CyberGenius I've found multiple results in working and not working.

Two problems:

  1. M.2 SSDs come in two interface types: SATA and NVME. The SSD you chose uses a SATA interface. As far as I know, in these models the WWAN slot only supports NVME. This is a hardware restriction. It's a bit harder to find NVME M.2 SSDs with a keying (the notches on the interface) that fits these slots, but they exist.
  2. Depending on your specific model and BIOS version the BIOS may prevent your system from booting even with an NVME SSD. This is an artificial blocklist that Lenovo puts in place. That would likely prevent ALL SSDs from working, because Lenovo never ships these with an SSD in the WWAN slot.

Not booting from the second drive wouldn't be a issue for me.

Because I want to use the second drive for VM storage (just in Windows).

 

So if I manage to find a NVME M.2 B+M key, then it will work? Or is there still a chance that it doesn't show up in Windows?

Sorry, I was unclear: If the BIOS is like mine, the laptop won't boot at all (from any drive) as long as an SSD is installed in the WWAN slot. The BIOS checks the installed module against a whitelist, and if it doesn't match, the BIOS literally stops the computer with an error message. Can't even enter the BIOS setup, the only way forward is to remove the SSD.

 

In my case, with a previous BIOS, I was able to install an NVME B+M keyed single-sided SSD, and it worked. Windows saw it, I was even able to boot a secondary OS from it, everything just fine. (Then I updated the BIOS.)

 

BUT: Just because it worked for me is no guarantee it will work for you, even with a good BIOS. Clearly Lenovo does not support this use case, and so for all sorts of reasons it could be that your machine is different and it won't work. The only way to know for sure is to try.

Thanks for your reply :)

 

May I ask which ssd you have? Because I can't find a nvme m.2 ssd, with b+m key in 2242 size.

I think it was a KingSpec (the 512GB version). Was available on Amazon at the time. I don't know anything about the brand, but this was one of the few I could find, and it worked.
