What could be the reason for Bluetooth not working when a second disk is installed in a laptop?

Question

Bluetooth

I replaced the native 2.4 GHz WiFi module in the Lenovo Z70-80 laptop with a new one that supports 5 GHz in addition to 2.4 GHz. The new module is included in the list of allowed ones in the BIOS, so it worked, but with a strange glitch - if a SATA HDD is also installed in the laptop along with the SATA SSD, then Windows in the device manager displays the 45th code for Bluetooth and that the device is not connected. It is worth turning on a laptop without an HDD, as the Bluetooth icon immediately starts working. There are no such problems with the old one. The hard disk is installed through an adapter instead of the native CD-DVD drive, and the SSD is respectively installed in its old HDD place. I can specify the models of the old and new WiFi modules, if necessary.
The problem is software or hardware, can anyone come across this and know how to get around it?

Answer 1

I say right away that the problem is very atypical, from the category "-doctor, why does it itch behind my left ear if you smear the heel with grease." I would only do this live.
Can I really tell you that in this lenovo the module sits in the M.2 connector. Wlan - via pci-e, and BT - via USB (both buses in the same socket).
If you dig in the power direction, you can start it with one SSD and a vlan, without a screw (the BT should work), and then "push" the basket with the hard drive onto the hot one. And look at the behavior of BT
A by interfaces - there shouldn’t be any collisions / problems at all, three independent interfaces .... I won’t assume anything from them

Answer 2

The laptop will not see the disk as "hot" if it is not specified in the BIOS. And since BIOS in laptops is cut to a minimum, then consider: you will never see it. Try after connecting the disk not to restart the laptop, but in the device manager to update the hardware configuration. If the problem is soft, then the laptop should fall into a BSOD.
And you didn’t think about the mechanical problem, how are the disk and bluetooth located relative to each other, as well as the bluetooth cable?
