Problem with Corsair K100 mechanical keyboard
Hello,
I purchased a Corsair K100 keyboard yesterday. It doesn’t turn on when the PC powers up, doesn’t light up, and I can’t access BIOS unless I connect another keyboard. Only removing its USB cable and reinserting it resolves the issue, and this happens again after rebooting. The PC is still new, with a ROG STRIX B550-F GAMING Wi-Fi mainboard.
Before restarting or turning it on, I attempted various solutions:
- Disconnected every other USB device
- Plugged the keyboard into all possible USB ports
- Updated the motherboard’s BIOS, even tried the Beta version (released in April 2022)
- Repeatedly updated the keyboard firmware
- Reset the keyboard by holding ESC (Corsair method)
- Reset the PC BIOS
- Experimented with different BIOS settings, such as legacy USB off and related options
I also tried connecting the K100 keyboard to my laptop, which works perfectly, but before assuming a hardware problem, I tested other keyboards on that PC—they all functioned correctly.
Any advice on what to try next? I considered downgrading the keyboard firmware (current version v.0.32.262), but couldn’t locate older firmware files for download. I searched online and didn’t find a solution; most fixes seem to involve resetting the keyboard while plugged in. In my case, it wasn’t necessary.
Thanks in advance.
Welcome to the forums, newcomer! To confirm your thread, are you using the most recent BIOS version? If yes, could you extract a BIOS version number? Is it feasible to determine the BIOS version before the update? How did you proceed with updating the firmware for the keyboard?
Thank you for your prompt response. I updated the Keyboard firmware using the iCUE tool from Corsair. It enables automatic or manual updates to the latest firmware from the internet.
For the ROG STRIX motherboard, I’ve used versions 2403, 2604 (the most recent stable), and 2803 (the latest Beta). In my view, the issue seems to be related to compatibility, likely with the motherboard itself. Since there aren’t many discussions about this specific combination online, it might be that only a few people have tried both models or that others have found a workaround.
