The notebook display itself does not work in WIndows (Win7 64). Boot to safe mode, BIOS, recovery etc it's there and works fine. But partway through booting up in "normal" mode the notebook LCD goes blank.
An external LCD works fine.
Going to graphics options, there is no option for the notebook display. In device manager, and enabling display of disconnected devices the Thinkpad LCD does show up as a disconnected device.
Again, booting to safe mode, BIOS setup or Thinkpad recovery the notebook LCD works just fine. Just not in Windows 7 normal mode.
Uninstalling the Intel video driver resolves this, reinstalling it brings the problem right back. Also have installed the latest version directly from Intel's site to no avail.
I should note that Fn-F7 brings up the menu, but changes nothing.

It's the Intel integrated card. I don't know the exact version numbers now. I pulled the latest from the Intel site, as well as the Lenovo site first to no avail.
I've given up and am doing a factory restore.

Doing a factory restore fixed the problem, but now I have just heard about a customer that had the exact same problem occur. On the same model machine.
Open a command prompt as administrator then run "sfc /scannow". If the issue is a corrupted system file this should fix it.
From the MS support site:
Some commands that you can run using Command Prompt might require elevated or administrative privileges. To run these commands, you can use the Run as administrator command.
In the search box, type command prompt.
In the list of results, right-click Command Prompt, and then click Run as administrator. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
