At a guess, you need chipset drivers.
The latest ones that Lenovo lists for the T400 are for Windows 8. I hope that these help:

What you need to do is go into Device Manager, right click on the unknown device, and click Properties. A new window will open. At the top, click on the Details tab. Right under Property, click the down arrow and choose Hardware Ids. Under Value, Right click on the first item that comes up and choose Copy.
Next do a Google search for the first item that came up. You can just Paste the item into Google search. That will tell you what device you are looking for. Then go to the Lenovo's website and download the driver.
PCI Vendor and Device Lists
Easier than Googling.
Try putting the device ID into the Device Search.
Just for future reference, before I do an upgrade or a clean install I always go into Device Manager, click the plus mark next to each device, this will show you exactly what hardware on your computer. Next take a picture of Device Manager with your phone. Be sure to get all the deceives. You may need to take a couple pictures to get them all. If you come up with any Unknown Devices you can look at your phone and see what's missing. You can do the same thing with Print Screen. Paste the picture into Paint and print it.

These are Windows 7 drivers. No idea whether they'll work with 10. Three options:
Run the installers. With luck, they work.
If they don't work, run them in compatibility mode.
If that doesn't work, extract the installers (7Zip, freeware) and run the installer manually.
Best of luck.
