After write the bios, i listen 10 beeps can you solve this for me, please ?
I still wait the wifi card that come from China.
Thank you
I have a Lenovo T440 (not T440p or T440s) and I need the whitelist removed to install a third-party WiFi card.
The one I am going to order is the Dell DW 1510 Half-Size Mini Wireless PCi-E WiFi N 802.11AGN card. If a whitelist removal isn't necessary, I would love to know. I updated the BIOS a month ago, so it should be the latest version. The only OS I have on the laptop is OS X El Capitan so if possible I would like to use that to do everything. I assume I will have to use Windows eventually, so I could make it dual-boot with a little work. Whatever info you need me to provide, just ask!
I have a public non-branded version of Intel 7260AC Wi-Fi module and used it for 2 years with a patched BIOS v2.19 on my Lenovo T440s (flashed by an external tool with desoldering the chip). Recently I've decided to upgrade the BIOS and prepared to patch v2.36, but was surprised by the fact that it works fine without any patch. I thought Lenovo eventually stopped the whitelisting, but yesterday I've installed v2.37 and my laptop stop booting with the well-known message about unauthorized Wi-Fi module. Then I've flashed back original v2.36 and everything is fine again.
I've unpacked several last BIOS versions for T440/T440s. In the range 2.32-2.36 there is the same LenovoWmaPolicyDxe.efi module of 4.2kb. Before 2.32 and after 2.36 there is another LenovoWmaPolicyDxe.efi module of 4.8kb, but also the same. To make things more clear I've digged into the LenovoWmaPolicyDxe.efi from 2.32-2.36 and I can say the whitelisting code looks like a sort of mess, but not a valid code. Also this mess looks unreferenced anywhere. So, most probably all of v2.32-v2.36 allow to install unbranded Wi-Fi modules (not just v2.36).
So if you have Lenovo T440 or T440s and BIOS v2.36, then you probably may install any Wi-Fi module. This is a good chance if you not familiar with soldering/patching.
To give it a try here is original v2.36 BIOS for T440/T440s

If your BIOS is newer, then you will need to disable the Secure rollback prevention feature in the Setup to be able to downgrade.
Here is info for v2.37. We can see that 2.37 fixes several serious bugs. So be aware of them if you decide to stay on v2.36.

It would be nice if somebody can confirm this with other Wi-Fi modules and also discover this bug on other Lenovo models.
I can confirm that I am able to run the Dell DW 1560 (Broadcom BCM94352Z AC WiFi + BT combo card using the m.2 slot) using this BIOS without needing to reprogram using external flashing tools. I was previously running a modded BIOS. (Using T440S)
Hi guys,
I have exactly the same problem and would be very thankful if anyone could help! The AC-7260 is really a mess...
Thx in advance!
In my case I have to find some who can write directly my BIOS chip... So no to easy...
And, yes the AC-7260 is peace of sh.. This is the worst WIFI what I've ever seen...
