<div dir="ltr"><div>Hi Bjorn,<br><br></div><div>I did the same trick when I installed
new wireless card in my older X220 - after flashing modified FRU
white-listed BIOS I had to load BIOS default to get my card working, but
there was slight difference - the card was showing in the rfkill
listing as HW blocked. As I remember correctly MC7455 is not listed in
rfkill at all, which is kind of strange... But I will double check it
tomorrow as I do not have NB with me right now. Thank you anyway for
suggestion, l will post rfkill list here.<br></div><div><br></div>BR</div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jun 7, 2017 at 9:38 PM, Bjørn Mork <span dir="ltr"><<a href="mailto:bjorn@mork.no" target="_blank">bjorn@mork.no</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">Dominik Strnad <<a href="mailto:litinoveweedle@gmail.com">litinoveweedle@gmail.com</a>> writes:<br>

</span>Don't know if this is relevant, but I seem to remember similar problems<br>
on my X301 when switching modems. IIRC the BIOS cached whether or not a<br>
modem was installed, and I had to reset this somehow after installing a<br>
new modem to get rfkill working again. My memory is a bit hazy as<br>
always, but I *think* I simply did a "load BIOS defaults" or whatever it<br>
was called in the BIOS setup.<br>
<br>
Might be worth a try before messing with the pin.<br>
