E7390 SSD in WWAN port

In my Latitude E7390 I can see an empty WWAN port described **bleep** "WWAN / SSD"

Photo of the motherboard (top-left corner): 

Can I place there an additional SSD harddrive like this one SATA III M.2 2242: https://www.goodram.com/en/products/s400u-sata-iii-m-2-2242-ssd/ ?

Not the one you suggested for 2 reasons. It is a SATA drive you linked to and that is a PCIe slot and that is a 2230 slot not a 2242.

From the owner's manual.

Secondary Storage:
128 GB M.2 2230 PCIeSSD
256 GB M.2 2230 PCIeSSD
 
Drives as below..2230

Thank you!

 

So definitelly a PCIe NVMe hard drive.

 

Regarding the form factor - seller of my laptop send me email that I should buy M.2 2242 form factor drive, not 2230.

OK, after further checking it appears that some retailers such as Crucial only supply SATA drives yet others such as Mrmemory state that PCIe drives are compatible. Are you confused yet...I know I am. The following posts should help. And since you have contact with the previous owner, what do they suggest as they obviously had a drive in there that was working.

I have bought the laptop from a reseller selling regualry hundreds of refurbished dell laptops (waiting for the NBD warranty transfer to my company - then I will be able to ask Dell Support for details).

 

This company wrote to me that in the WWAN/SSD port I can mount  PCIe NVMe M.2 2242 SSD hard drive (without any specific example model, although ie. Toshiba RC100 fits these requirements.

Hi,

I have a Dell 7390 2 in1 and have installed BG2 M.2 2230 Toshiba 256 Gb PCIe in WWAN port and It works fine.

You will need a proper bracket to install this SSD as SSD is really small as compared to room available :-).

 I have also upgraded my primary slot with SSD7 M.2 2280 PCIe NVMe 1TB. Both SSDs are working good.

By the way, I have made Secondary drive as my system and boot drive and have observed no difference in loading software or starting windows.

Regards,

Hey - I’m a little late getting in on this - sorry.  Where would I get the bracket to mount the SSD in the WAN port? Do you have a part #?

Thanks so much!

Welcome to the Dell Community  @MWA_JeffW 

He installed an M.2 2230  30mm

If you install an M.2 2242 42mm you should not need a bracket.

Can you check your size just to make sure???

Best regards,

U2

@MWA_JeffW 

Does the BIOS see it???

Does Windows see it when you try to install the OS???

Ok - I have the drive and I installed it.  I get "no bootable devices" at power up.  What am I missing?

Toshiba OCZRC100

M.2 2242 PCIe NVMe SSD

Any help, please.

Thanks for the response.  There is no OS.  I installed the drive in my laptop so I could install the OS.  On boot it shows no bootable devices.  The laptop does not  recognize the drive in the WAN port.

No - the BIOS doesn't see it. With just that drive in it, there is an error message when the computer starts: No bootable devices. When I enter the BIOS it shows no HDDs. The BIOS version is 1.3.3

I updated the BIOS to the newest version - 1.9.3.  My situation has not improved.  The system does not recognize that anything is in the WWAN slot.  Is there something I need to turn on in the BIOS or??   I'm at a standstill.

Thanks, by the way, for the help so far.

@MWA_JeffW as previous posters in the thread have suggested, the slot will only accept the 2230 style drive with an additional bracket. The drive you have purchased, the 2242, doesn't work with that slot hence why it is not being detected.

As per JOceans post

Not the one you suggested for 2 reasons. It is a SATA drive you linked to and that is a PCIe slot and that is a 2230 slot not a 2242.

Also confirmed as working by ProcessSoft
