It seems that the Razer keyboard in the studio has a bizarre problem. There is an issue with the 9 key. When it is pressed 89 is show on the screen instead of only 9. Same with the ( key which shows 8( so the low level keyboard logic is borked. Pulling the keycaps off showed no damage or dust to explain the fault.
Razer suggest unplugging the keyboard and restarting the computer. I already have installed a spare keyboard as I need proper functionality.
This fault is known from the off forum post where a keyboard failed. The keyboard CPU seems to be working but the ROM containing the character codes seems to be faulty. Given the ROM is hard coded and the CPU core is also embedded as a SoC there is no repair possible.
I also dislike their spyware package of software that demands signing in etc. Privacy matters.
