I have swapped the keyswitch to “Matias Quiet-Linear Switch”, with advice Swapping out keyswitch mechanisms. It worked without any problem for 3 days.
Then the right half suddenly have no response, only some of the LED random keep on, and the left half works fine.
Here is what I have tried:
- Pluging into other PC.
- Refresh the firmware.
- Open the left enclosure to press the hidden rest button, then refresh the firmware.
- Change the line which connected the two half to the short one.
