I just had a K70 MK2 refurbished (red keys) delivered from SCAN 4 days ago and every key is working except the delete key below INSERT.
The delete key does not put me into the BIOS on startup.
The delete key below numpad 3 does work.
The onscreen keyboard delete key is detected.
What I've tried:
Factory reset through https://help.corsair.com/hc/en-us/articles/360025465031-How-to-Reset-your-keyboard
Exiting iCUE
iCUE version: 3.36.125
Firmware version: v3.24
Is this a hardware issue and should I use RMA?
EDIT:
As a side note, with iCUE open, using the volume spinner too fast can lock the volume at 0/100 and lock the keyboard.
This does not happen with iCUE closed.
