I disassembled my Realforce R2 to lube the stabilizer last week.
After the keyboard was reassembled, I found that the last row of keys of the keyboard lost its tactility and the a actuation force became very low. It feels like the PCB is not fixed to the steel plate very well, but I have checked all the screws at the back, all of them were tightened. I tried resitting the dome and spring, but didn’t help.
Any idea about this issue? Thank you.
