Security - IO Port Access)Ĭan someone clarify for me what's up with the USB lines on the mPCIe ports of the T420s?
Forgot to add that both have Bluetooth enabled in BIOS (i.e. I did install the latest Intel Pro Wireless software package as well as the Intel BT software - but still no dice on T420s #2 - I originally saw the BT in Device Manager but it disappeared after. Lenovo T420s i7 <- this is the T420s that BT didn't work after installing the AC7260 wifi card until I taped PIN 51ĭid not come with Bluetooth (no BT indicator light on screen bezel) Lenovo T420s i5 <- this T420s worked right after installing the AC7260 wifi + BT cardĬame with stock Bluetooth (I can tell as the BT indicator lights up on the screen bezel)ĭisabled the stock BT and everything works well.Ģ. Now everything works flawlessly after taping PIN 51 on the card.Ĭard I am using in both T420s: Intel Dual Band Wireless-AC 7260 2x2 Network plus Bluetooth adapter ()ġ. The one without stock BT had issues and I finally stumbled by accident the Pin 51 tape trick.
One that had a stock BT worked flawlessly after I installed the AC 7260 card.no issues (I disabled the stock BT adapter and only have the AC7260 BT enabled). Both have whitelisted BIOS and I installed the Intel AC7260 + bluetooth Wifi cards.
Hoping someone can help explain this to me.
