This is kind of a strange problem.
My internal keyboard on my Yoga X380 lower half of my keys (shift to shift area) sometimes don't respond when I press them.
Keys work fine on a external usb keyboard so its the internal keyboard.
This has been going on for a few months after I got the unit and the only way to fix it is to reseat the keyboard connector on the mainboard.
I've worked with Lenovo support and had the keyboard + mainboard replaced but it keeps reoccurring after a few days.
I work in a semi static safe environment (no carpet + hard floor/table) and my previous Lenovo X250 didn't have this issue.
I also have other coworkers that use the same bench with Yoga X370 that don't have this issue.
All I have connected is the power adapter, Thinkpad USB 3.0 pro dock and Plantronics Voyager Legend bluetooth headset.
My usb mouse is connected to the docking station which has 2 external monitors + network cable connected.
I've swapped out the power adapter and docking station, same issue.
This issue seems to happen when I fullly shutdown the laptop for the day and store it in a secure cabinet.
Next morning when I power it up, it has the issue (the issue never starts to happen when the unit is active, always after a full power off).
I've updated to the latest BIOS 1.23.
Looking for any suggestions.
