For a general overview of laptop-related articles and recommendations, see [Laptop](/index.php/Laptop "Laptop"). ## Contents * [1 firmware (e.g. bios and peripherals)](#firmware_.28e.g._bios_and_peripherals.29) * [2 kernel and hardware support](#kernel_and_hardware_support) * [3 mobile broadband](#mobile_broadband) * [4 lspci and lsusb](#lspci_and_lsusb) * [4.1 lspci](#lspci) * [4.2 lsusb](#lsusb) * [5 Configuration](#Configuration) * [5.1 Smartcard Reader](#Smartcard_Reader) * [5.2 Fingerprint Reader](#Fingerprint_Reader) * [6 See also](#See_also) ## firmware (e.g. bios and peripherals) As of writing, the current bios version is 1.0.7\. By visiting the downloads section (for the type HG/HF T470s) an iso can be downloaded and burned to disk which will perform the update [[1]](http://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t470s/downloads) This laptop is unique in that it retains the thinkpad dock connection as well as provides docking ability over USB-C. We have tested with the [Thinkpad Ultra Dock](http://www.thinkwiki.org/wiki/ThinkPad_Ultra_Dock) and are able to utilize multiple HiDPI monitors via individual connections (e.g. no display port chaining). There are published [firmware updates](https://support.lenovo.com/us/en/solutions/pd014572) for the dock that require windows to install. DisplayPort chaining works via USB-C to DisplayPort adapter. ## kernel and hardware support Installation with modern media puts you on Kernel 4.10.10-1, however [this note](/index.php/Dell_XPS_13_(9360)#NVME_Power_Saving_Patch "Dell XPS 13 (9360)") made [linux-mainline](https://aur.archlinux.org/packages/linux-mainline/) seem essential. As advised in [Intel graphics#Enable early KMS](/index.php/Intel_graphics#Enable_early_KMS "Intel graphics") and [Kernel mode setting](/index.php/Kernel_mode_setting "Kernel mode setting") you can add i915 to your modules. [Hardware video acceleration](/index.php/Hardware_video_acceleration "Hardware video acceleration") with Kaby Lake seems to work fine via va-api. On [gnome-shell](https://www.archlinux.org/packages/?name=gnome-shell) via [wayland](/index.php/Wayland "Wayland"), suspend-resume results in the fan holding at 100% without ever spinning down. Alternatively if you use [xorg](/index.php/Xorg "Xorg") this doesn't seem to happen. Upgrading BIOS/UEFI seems to solve the issue. ## mobile broadband The mobile broadband card is a [Sierra EM7455](https://www.sierrawireless.com/products-and-solutions/embedded-solutions/networking-modules/), which can be seen below in the lsusb. We have confirmed working with with [Google's Project Fi](https://fi.google.com). ## lspci and lsusb On kernel '4.11.0-rc6-mainline' via [linux-mainline](https://aur.archlinux.org/packages/linux-mainline/) on a *20HG* T470s ### lspci ``` 00:00.0 Host bridge: Intel Corporation Device 5904 (rev 02) 00:02.0 VGA compatible controller: Intel Corporation Device 5916 (rev 02) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI #1 (rev 21) 00:16.3 Serial controller: Intel Corporation Device 9d3d (rev 21) 00:1c.0 PCI bridge: Intel Corporation Device 9d10 (rev f1) 00:1c.2 PCI bridge: Intel Corporation Device 9d12 (rev f1) 00:1d.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #9 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Device 9d4e (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.3 Audio device: Intel Corporation Device 9d71 (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (4) I219-LM (rev 21) 3a:00.0 Network controller: Intel Corporation Device 24fd (rev 78) 3c:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd Device a804 ``` ### lsusb ``` Bus 002 Device 003: ID 0bda:0316 Realtek Semiconductor Corp.

[libfprint bugreport](https://bugs.freedesktop.org/show_bug.cgi?id=94536). Synaptics (which has acquired 'Validity Sensors') has unofficially said that they cannot disclose the protocol, but may possibly release a binary driver. Open source Linux driver is being developed by reverse engineering the Windows driver.
