So i got this New razer cynosa v2 today and some of the Keys doesnt work like My space backspace C and N doesnt work idk what is wrong but I would like if you Guys could help me
Did you install the Razer Synapse software? Also you can try unpluging it, then holding Esc + Caps + Spacebar and plugging it back in. After that you can release the keys, that worked for my Razer Huntsman a few days ago. If that doesn’t help just try other USB ports. I hope I helped and make sure to let me know if it worked!
