This is list of Windows 10 (64bit) T420 drivers that might be useful to someone else and to make sure I have the latest version of «all the things,» and whether I missed anything. All tested on my personal T420-4180CM6 (except SmartCard and Fingerprint Reader, which I don’t have). It should make most of the FN keys work, among other things.

Not all drivers are absolutely necessary, a lot of things work okay with the genericAF Windows drivers, I just made this list to be thorough. Some of the Windows 7 drivers are actually newer than the generic Windows ones…

IMPORTANT NOTES NOV 2019

I’m currently working on updating this list, Lenovo in their infinite wisdom keeps mucking with Vantage, which wreaks havoc with the house of cards that is the combination of Lenovo PM, Lenovo Power Management, and the Lenovo Interface Foundation.

A lot of this just installing the new driver doesn’t work, you have to manually update via Device Manager, a number of system devices will find updates from M$ if done manually — I added a list of the devices this works for below.

Mini-rant about «Driver Updater» Software

I’ve tried a lot of them, they’ll try to get you to pay money to install drivers from dubious sources that won’t work for your system anyways. For example, the 12.x.x.x version of Bluetooth drivers are for BT4.0 and make 3.0 devices not work.

If they told you the truth about your system being up to date and didn’t find anything, they wouldn’t be able to scam you into buying a copy.

Windows 10 1903

I did have to «force» the update using the Windows Update Tool as it was giving me the «Your Device Isn’t Ready.» So far, everything seems to work just fine with a few exceptions:

1. The Camera App didn’t work even with the default drivers. I forced the Realtek drivers AGAIN and it works. (see below for more information)

2) A «MAP SMS/MMS» in Device Manager with a question mark when a cellphone is Bluetooth linked. Under «Devices and Printers» in Control Panel find your mobile device -> right-click -> properties -> services tab. Uncheck MAP SMS/MMS.

Windows 10 1909

No notable issues thus far. At least not driver-related ones.

Windows 10 20H2 UPDATE IMPORTANT

DO NOT install any Conexant drivers, just use the windows default.

I had to do a clean install of windows 1909 with no drivers installed and let it update from that. The various epic things I tried to do to get rid of the conexant drivers didn’t work, and 20H2 went into a bluescreen loop.

Quirky

It took some wrestling with Windows to make it keep these and not auto-install ones that didn’t work — namely trying to install Ricoh drivers when it’s not a Ricoh device. If your camera isn’t working after installation, check to make sure the driver version matches the correct manufacturer (ie, not Ricoh) in Device Manager.

It didn’t seem to matter which device I picked when manually installing the driver, as long as I picked one of the Realtek ones.

Under Device Manager -> Details -> Hardware ID’s VID_04F2 is Chicony, which uses a Realtek Chip.

Integrated Camera Driver 10.0.18362.20112

    https://support.lenovo.com/us/en/downloads/ds502998

Brief instructions for «Forcing» the driver:

    Update Driver

    Browse my computer for driver software

    Let me pick from a list of available drivers

    Have Disk

    Copy manufacturer’s files from C:\DRIVERS\CAMERA\N29CA04W (default location)

    Realtek -> Integrated Camera (may have to experiment with which Realtek to pick)

    Update driver warning [Yes]

Additional note — the W10 Camera App is . . . quirky (to put it nicely) about detecting the camera. The camera may still work in other apps. I personally found an OEM version of Cyberlink’s YouCam 6 that (A) works more consistently and (B) offers more functionality than the W10 App.

For some users, the Rico SD card thing causes 100% cpu usage, either disable/enable in Device Manager as needed or just get an external card reader.

Thermal Controls

In my experience the T420 runs hot, TPFC is needed to make the fan run full speed (~6000rpm)

I use Throttlestop set up to still allow throttling for safety, but only down to 2GHz instead of 800MHz

ThinkPadFanControl USE v063 for T420

    https://thinkwiki.de/TPFanControl

ThrottleStop 8.70.6

My TPFanControl.ini temperature section (T420 w/ 4200M)

My ThrottleStop settings *Updated, using ‘set multiplier’ instead of ‘clock modulation’ kept it from downclocking @ idle.

Available via Manual Update

The chipset drivers above seem to work fine, if you like you can manually update the following. (Go to Device Manager and use the ‘Search Automatically’ option. For some reason Intel now dates their chipset drivers to 1968 so they won’t over-ride existing drivers — this is the work-around.

At the time of writing, the version for these is 10.1.1.38

Notes:

Rename the files when downloading to something besides the garbled Lenovo names.

Low volume: Control Panel -> Smart Audio -> Click headphone picture -> Disable «safety»

Lenovo Power Manager no longer supported, use Lenovo Vantage to set charge threshold.

IME Security Risk: Disable or leave as «unknown device»:

    Ports (Com & LPT) -> Intel(R) Active Management Techology — SOL (Com5)

I didn’t bother listing the cellular adapter, it took up the valuable mSATA slot.
