I have a Thinkpad Helix that suddenly started showing strange behavior. The user reported that it wouldn't wake up from sleep state. She brought it by the show us and it wouldn't boot at all. While troubleshooting I realized that removing it from the keyboard would allow it to start.
Here is what I know:
The user has only had the tablet since the begining of May.
We removed windows 8 and installed windows 7 per the users request.
The keyboard dock firmware is up to date.
If I turn the tablet on first and then insert it into the dock, it will stay on and it will charge, but no inputs are received from the keyboard dock.
At this point I'm thinking hardware failure. Any thoughts?

When you attach it to the dock, do both batteries appear in the notification power icon?
You might just have to reset the dock.

They didn't at first but after resetting the dock the second battery shows. However, the keyboard and touchpad still won't work. I reset the tablet as well and saw no change.
I should also mention that being attached to the dock is preventing booting to the point that restarting while the tablet is attached to the dock causes it to shut down and stay shut down.

Well, that is a bit of an improvement, albeit not much. If you enter the Device Manager, do you see any
devices disabled or displaying the error triangle?

Besides the keyboard and clickpad not working, do the external ports, USB/DP work?
Since the machine is not running the Pre-installed Windows, this here registry fix might apply.

Both of the USB ports work on the keyboard dock.
I applied the registry patch and it didn't do anything. I would have been surprised if it worked considering everything had been working find previously.

Have you tried re-flashing the 1.15 firmware for the keyboard dock?
