ThinkPad P50 Intermittent Keyboard Issues
Posted: Thu Aug 25, 2016 11:29 am
I recently ordered a ThinkPad P50 for work and I am finding that the internal keyboard periodically goes unresponsive for a short duration (30 seconds to a few minutes). The system is running Win10 with the latest firmware and drivers from the Lenovo site.
The trackpoint and trackpad continue to work in this fault condition. And most of the time, some of hotkeys (microphone mute) continue to respond, even though the rest of the keyboard (caps lock, num lock, normal keys) do not seem to register. I can always plug in a USB keyboard and I will be able to type. Sometimes the act of plugging in a USB keyboard will cause the internal keyboard to respond, but not always.
I've also tried re-seating the ribbon cables from the keyboard, but that has not solved the problem. The problem occurs even with Windows 10 in safe mode.
Has anyone experienced this kind of problem or have any suggestions? It's intermittent, so I'm hesitant to contact Lenovo Support because it may or may not show up when they are observing it.
