Re: x1 Carbon 4th gen (20FB) intermittent keyboard issues

Got similar issue that keyboard & trackpad not working after a Lenovo system update, finally uninstall and remove the Trackpad driver (Need to be removed!!!) from device manager, run the hardware checking it installed the driver from Windows update and reboot, the trackpad and keyboard working again!

Re: x1 Carbon 4th gen (20FB) intermittent keyboard issues

Hi,

My three week old ThinkPad has just experienced a similar issue. Keyboard stopped working and machine failed to re-boot. Power light is on, but system is totally unresponsive. Is there a reset button on these?

This just happened to me. We only have one computer so we have any other laptops stacked on top, but we tend to rest our phones on the laptop. That being said, nothing is responding. The USB ports are putting out power and the power button is lit up but I can't power the machine down (even by holding down power button), get the screen to turn on, or anything.
