G-Series Gaming Keyboards

[Coda]

Hi,

I bought a used G15 V2 (Orange) because my V1 screen died.

Everthing was ok with it, but one morning last week I turned on the PC to find that the Enter key was not working. I did further tests and found also that the Backspace key, and the numeric keypad 2 key is not working either.

I did some reasearch and found lots of posts (not just on Logitech forums) with people having had the same issue:

Some said to replug it, some said that worked, others didn't.

Some said to reboot PC, some said that worked, others didn't.

Some said to re-install drivers, some people said... you get the picture.

I have done everything but re-install the drivers. Why not? you may ask. Because I don't think this is a driver specific problem. If I cold boot the PC (even after standby power has been off) and go directly into the BIOS, the enter key still doesn't work. Windows is not loaded, so therefore neither is a driver.

I plugged the keyboard into my laptop, windows found the device, installed a generic HID keyboard driver, and I tested it with notepad. Same problem. That's on a different computer, with no logitech drivers installed. My V1 G15 does NOT exhibit these issues. Apart from the LCD being dead, it's still fully functional and recognised and programmable with the LGS software.

So, there are 2 possible issues here that I can think of. 1. The logitech driver software has borked the keyboard somehow (possibly by flashing a bad macro sequence), or 2, an actual real hardware fault.

Has anyone spefically found the reason for these failures that have hit so many people?

Thanks in advance.

BTW - Using Logitech gaming software 8.20.74. which is relatively new.

So nobody, including the millions of geniuses on this forum knows what causes the issue?

Hello Coda,

Since the issue followed the G15 to a different computer, this indicates a hardware failure. The G15 does not have on board memory so it can not be caused by a profile.

Best Regards,

Right, confirmed. I've disassembled the keyboard and plugged it in to find that the keys were working again. That was yesterday. Everything was fine until 5 mins ago when the same fault re-appeared. Must be a broken trace/membrane/connector somewhere. Oh well. I have another used V1 arriving in the post this week with a working screen so this one can go in the trash.
