Windows 10: Specific Keys Not Working and Unexpected Sleep Combinations on External Keyboard

I am facing issues with my external keyboard Zeb Companion 107:Specific keys such as Left Ctrl, F1, F2, `, =, -, 5, and 6 intermittently stop working. When they fail, all these keys stop functioning simultaneously and start working together at the same time unpredictably. Keyboard diagnostic tools show that pressing Right Alt also triggers Left Ctrl even when Left Ctrl is not physically pressed.Certain key combinations on the keyboard cause my PC to go into sleep mode unexpectedly. These combinations include:Ctrl + Tab + `Ctrl + Caps Lock + F1Ctrl + F3 + F2There can be even more there is a p

Specific key combination not working on specific keyboard

I don't know if this is the right community to ask in, but I've seen several "plausibly" equal questions.

I'm baffled here (after 20+ years working on IT), and don't know what to do next.

The specific key combination for the key [ is not working on my system (Win 10 Pro x64). In my keyboard layout (es-ES), this is achieved pressing AltGr + `.

This is a Microsoft wired Comfort Curve 2000, with Spanish layout

At first I had assumed I could have changed my layout, however:

• That key is working fine without AltGr, ` and ^ (that's normal and Shift for that key) works fine.
  
• The rest of the keyboard works fine, correct layout
  
• Other keys requiring Alt Gr work fine
  
• The layout is correct (both language and variation) in the control panel
  
• It works fine using other keyboard in the same system
  
• It makes no difference plugging the keyboard on other USB ports
  
• It worked fine till this morning (I was programming with it yesterday, I'd have noticed the lack of ['s)
  

I've tried removing the HID device from the Device Manager and installing it again. Also tried reverting back to the "Default" input USB device driver (instead of the specific Microsoft one).

I'm out of ideas... any hints on what to look for? Maybe hardware fault? I'm ruling out the hardware fault because other AltGr combinations work fine, and that specific key works fine also, it's just the specific combination of AltGr + ` which is failing... but I might be wrong.

I'll probably go and buy another keyboard, because I need to code, but if there's any hints you might give that save me the money, I'll appreciate them.

 

Key combinations not working

Thanks for following up. In here, you can find the list of all the keyboard shortcuts in Windows 10. Check it out and
see which key combinations are still working on Windows 10, and which are not.

We also tested on our end and only the Alt + F and Alt + P are working fine, and this is on a PC that is on the Fall Creators Update. May we suggest that you update your operating system to 1709 and see if the key combinations will work.

We'll keep an eye out to your response.

 

How to reassign a keyboard key combination to a specific key?

How do you reassign hot keys?
You can do this easily with Autohotkey (free). (And much much more- including manipulate windows and buttons and create small programs).
