Have them all running Windows-7, 32-bit, with SSDs (using IDE to mSATA converters).
Installed a 39T0026 modem card in place of the 91P7657 ... and everything I read says this should be a modem card WITH bluetooth. Yet when I look at the devices on the system (Computer, Manage), I see no bluetooth ... nor any card with a yellow exclamation point. When I run the EXE that installs bluetooth, it says I don't have it.
Am I forced to run a dongle?
You need 91P7315 for a modem with BT for in an X31.
PS: I have two very nice X31 machines lying around, PM me if interested.
Thought about an "RF signal off" feature, but could not find one in the BIOS, OS, or keyboard.
Found one of my laptops did originally come from the factory (only the 2672-J7U, JXU, JHU, or JBU came with the BlueTooth option installed). But again, the BT in that would not run ... so I spent about 4 hours trying different combinations. Finally found a 'readme' file that reminded me to press Fn/F5 to turn on the BlueTooth ... and on the JHU optioned X31, the keyboard does have the F5 shown as an RF signal. Press that Fn/F5 combo and came right on.
Went back to an X31 without BT originally installed (thus, no antenna) installed the BT/Modem card. But because it did not have BT originally installed, there is no icon on the keyboard ... but pressed Fn/F5 and BT immediately came on.
