For some days now, I have a problem with my Lenovo Thinkpad T470p keyboard. Before all : I've already updated drivers and shutdown my computer.
Here are the problems :
- The light of the caps lock key is like 50% lighted up in permanence (see the photo). Of course, before, the light was off.
- When I hold the shift key and then press the space bar, it doesn't work.
- When I hold the shift key, and then press letters, some append 2 letters. For example, pressing shift + B appends "BT", shift + T appends "BT", shift + Y appends "NY", shift + N appends "NY".
It seems to be the only keys that have a problem.
The caps lock key in its normal state (abnormally 50% lighted up):
The caps lock key in its uppercase state (normal 100% lighted up):
Have you an idea of what could be the problem?
