The list of manufacturers which are a problem is uniquely ours developed from
reports by others. We see the issue frequently enough too. IBM and HP are
probably the ones we have encountered most although this is just coincidence.
I think Dell may have only recently started doing this and Toshiba just
doesn't have much market share.
Not all the Mini PCIe network card issues you will come across are
specifically because of this though. Generally our experience is the system
won't boot or will otherwise pop up an error message when there is digital
restriction in place. It is clear with the Lenovo/IBM laptops as they pop up
a "unauthorised" message.
There is extensive documentation for Lenovo/IBM at the URL below and there
are some complicated solutions to the problem too for some models. Applying
such fixes though can be disastrous though as they often (?almost always?)
involve modifying the BIOS. You could end up with a system that does not
boot.
