Intel AC 7260 w/Pin 51 Removed on My T520 (Pics Link)

Hi Gang.

My T520 (4242-AB9) was one of my few Thinkpads without Bluetooth, a means of communication which I use almost everyday in some form or another.

I had an old Bluetooth 2 card from another Thinkpad at hand and installed it. It worked ....sort'a...OK, and I could connect to different Thinkpads, but not reliably to either my BBY phone nor my Yamaha P515 piano. Out it came.

My router had been changed out some time ago to a TP-Link AC 1750, and other Intel AC 7260 with BT 4.0 cards that I had used in other Thinkpads have averaged anywhere from 650-850 Mbps in speed so I was happy with that card and wanting to replace the Intel 622AN card that was in the T520. Added bonus....better/faster Bluetooth (I hoped!)

I have a Samsung EVO mSata 500 Gb card in the WWAN slot and did not want to forgo it, so into the WIFI slot the new 7260 card had to go. First install with no pin 51 taped, and the WIFI was a success, but of course, no Bluetooth.

Second install with pin 51 taped (scotch tape) was a disaster! Three tries at an install, and I ruined the tape every time when inserting the card into the slot....Sorry, no pics of THAT....too embarrassed at my ineptness/clumsiness with scotch tape :oops: :oops: :oops:

Pin 51 removal here we come!

Hit the slideshow button.

I used the smallest jewelers file I had in the set, and the flat side was the width of about three of the pins....the edge side, though, was an almost-perfect fit for grinding just one pin. It took a few minutes of careful one-way grinding to get the pin removed, but when all was said and done, it was a clean removal, with only minimal scraping of the adjacent pin.

( I first thought of digging out the Dremel.....Heh Heh Heh...I'll have this Puppy fixed in NO time!!...but.....yeah...... :BAAAD!:. One slip @ 10,000 RPM and I can only imagine how my new 7260 card would function with NO pins!).

Into the T520 and install the software ( The latest Intel AC 7260 WIFI/Bluetooth software [Ver 20.10.2 Proset Win 7 - 10 X32/X64 Versions can be downloaded here:

https://downloadcenter.intel.com/downlo ... duct=75439

Success with both WIFI and Bluetooth :D . WIFI connects to the router at 750-800 Mbps, and I'm now happily BT4- connected to my Yamaha P515 Digital piano, the BBY phone and the rest of the Bluetooth-enabled Thinkpads around the house.

A few downsides of course, which I can live with...NO Bluetooth indicator on the clear-plate. The hardware On/Off Switch does NOT turn on/off the Bluetooth portion of the card (It DOES turn off the WIFI though). The 7260 card is NOT recognized with Function/F5 either. (Turn the card on/off via the Intel software (BT icon in the Taskbar.)) I have Access Connections installed (Win 7 Ultimate O/S) and that program DOES recognize the card/signal, WIFI Profile, etc.)

Hope this helps anyone who runs into problems getting this card's Bluetooth 4.0 to work in a non-Bluetooth enabled Thinkpad.

Let me know if the pics link gives any problems or if you have any questions.

Regards.

Dave

Would taping the 51st pin on an AC 7260 work for a T530? I saw a video with someone using black electrical tape for an X220 and it worked. I just got a T530 on eBay and looking to upgrade various things on it, after updating the drivers, BIOS, etc.

If you you'd be fine with modified bios then you could take a look at 1vyrain. It removes bios's "allowlist", allowing installation of any WLAN/WWAN card in your laptop. I personally done that on my X230 and can't complain, I have been using 7260 for few months now and it works just fine.
