I’m experiencing an issue with my Razer BlackWidow V3 Tenkeyless keyboard, purchased in 2021. In the past, one of the keys stopped working, but I was able to fix it by manually installing a firmware update. Recently, however, a new problem has appeared: several letter keys, such as U, O, and E, only work intermittently or very rarely. All drivers, software, and Razer Synapse are fully up to date. I plan to test the keyboard on another computer to rule out system-related causes, but at the moment I don’t have the ability to do so.
I’m not sure whether this issue is related to the age of the keyboard (even though it has been well-maintained, never damaged, never exposed to liquid, and always cleaned carefully), or if it’s another software-related problem. I’ve already reinstalled the software several times, but manually updating the keyboard firmware doesn’t work because it says the device is already up to date.
I’m looking for potential solutions or explanations for this issue, and I’m wondering if anyone has experienced something similar. I’ve heard that cleaning the switches with isopropyl alcohol can sometimes help, but I’m not sure how effective or safe it is for this specific keyboard. I really care about this keyboard and would like to avoid replacing it if possible.
