Spare parts finding for Precision 7540

Im trying to find and purchase the following list of parts compatible with a Dell Precision 7540 service tag 

<To protect you, your private information was removed from public view. All private data was saved to your private Case. DELL-Admin>

The spare parts page was not helpful.

  • A WWAN card
  • A 2.5 inch SATA interposer module. Reportedly, part number is typically PRW9D
  • A caddy or bracket for the drive.
  • A 64 WH battery, for compatibility with the 2.5 inch drive.

This is a 2019 system, so Dell likely won't have the parts.  Try parts-people.com or EBay.

The WWAN card is a standard part, and you should verify support with whatever OS you're running and with your service provider.

same goes for the interposer. lot from china, one from slovakia
