You can do that, but you also need to replace the original camm interposer. The interposer used along with the pure CAMM board is thicker than that used along with the SODIMM daughter board. You may ask the Dell Advisor to order the daughter board and interposer.

A thin spacer is needed when your case is not a performance one. I installed the SODIMM mechanism on a thick spacer in the performance case and everything works. Buying a thin spacer for a performance case is a waste of money.

To note. WWAN cards/slots are B key and NVMe drives are M key. You need an adapter to fit a NVMe drive in the WWAN slot.

 

I'm talking about something else, why use an adapter in WWAN if you can install a 2230 SSD instead of a Wi-Fi module. If DELL allows the installation of a 2242 in WWAN, you could have bought a 2242 SSD and adapter in the store DELL, but the store only had 2230 SSDs and this instead of the AX211. Of course, we understand that to sacrifice the AX211 for an SSD, we need an alternative for wireless internet, and such a sacrifice is acceptable if we have a working WWAN option.

Did you install the 2230 SSD in the WWAN via an adapter? The WWAN is 3042. The 2230 SSD can be installed instead of the Wi-Fi module.

 

 

No i only use 2242 SSD.  SN520 works, but under device manager>USB, a ! USB item will intermittently appear and disappear thru out the session, not affecting actual use. Earlier i thought it is because of other peripherals since i connect to the Dock 90% of the times.

 

I have emptied the WWAN slot for 2 weeks since it is not performing to its max.  SN520 can only run at 260MB/s.  Other SSDs that can run at >1GB/s need to go thru a guaranteed blue screen crash everytime the laptop boots.

as far as I understand, the photo shows the display cable for the version with an infrared camera, but the camera is not included with the cover, probably you need to transfer the camera and display cable from the old cover or buy a new
