Running the latest Windows 10 64-bit, all drivers up-to-date according to the Lenovo tools, but the only key that seems to work on the keyboard is the Function Lock key in the upper-left and the Windows-logo key. All others, when depressed, result in no input to the system.
Has anyone else experienced this? Is this a faulty driver issue in a recent update? Or is this a hardware failure?

Oddly enough, yes. I just powered up the machine and before the Lenovo splash screen, it allows me to toggle that off. As the system comes up, it re-lights. NumLock goes off when the Mute is toggled, but by the time the OS comes up, both are back on and cannot be toggled off.
Other keypresses result in no response once the OS is up.

I restarted and entered Safe Mode. Using Notepad, the built-in keyboard remains unresponsive while the external works. Speaker mute, etc. operate the same as before and cannot be toggled off. CapsLock also cannot be enabled. Esc/FnLk does work, however.

Lenovo is shipping me a box for the unit. I presume this is a hardware problem and not a driver issue? I have seen reports that the Synaptic drivers cause issues under some conditions and Registry changes sometimes work. I would prefer not to ship this in if it's not necessary and can be corrected with a driver or software change.
Any more suggestions?

'twas a good idea, but...
Booted from LinuxMint live media and while some behaviour changes - NumLock and Speaker Mute are not enabled post-boot, most behaviour remains the same. No input from most keys on the keyboard, NumLock cannot be toggled, etc. So this is a hardware failure it would appear. Again.
This will be the 4th mainboard in this machine in 8 months. This is becoming tiresome. This machine is obviously a lemon. I'm going to push for a swap with a new, non-horked machine.
Thanks for the input, though.

After testing with the Live linux yesterday and powering it down, I wanted to power-up this morning and pull data off of the two SSDs before shipping back to Lenovo for repair. Now I have no video on the built-in display.
