Hi,
 
I've not found any other thread on the internet that describes this same problem. I hope someone out there can help. :-)
 
The keyboard does not work properly. The Num Lock button turns off intermittently every few seconds, as though there was a lack of power to the keyboard. While it is off, I cannot type. 
 
I have a USB hub on my computer screen. USB cable goes from my computer to the screen, and at the screen I connect my keyboard and my mouse. It has to be this way, as the screen is too far from the computer to do otherwise.  
 
The computer functions normally otherwise. I have double-checked all my power saving options and updated all my drivers. Windows boots normally. I have tried changing USB keyboards. I tried changing the USB cable from the computer to the screen. I also tried changing USB ports.
 
Any ideas on other things to try?

Open the Device Manager and scroll down to Keyboards .

 

Click on the diamond to expand the tree.

 

Double click you your keyboard, select Driver, then select Uninstall.

 

Restart the computer, a new driver will be installed.

Thank you. I tried that already as well, it did not help. 

 

Sometimes (right now) it works. Other times, I can't type more than three words at a time in between the light blinking on and off. So strange...

Have you tried another keyboard?

I appreciate the help friend, but as I already stated in my OP, I have updated all the drivers and tried another keyboard etc.

 I'd get a USB extension cord and run it directly from the computer to the keyboard.  If that doesn't remedy the problem, you could possibly have a motherboard problem.  How old is this computer?

 

 Good luck.


Make regular full system backups or you'll be sorry sooner or later.

I tried that, thanks Niweg. Works just fine if I'm connected the keyboard directly to the computer. It's quite a well-built computer with a 3rd generation i3 processor. Only three years old. 

 

By the way, it's failing again. It took me about 5 minutes just to type these two lines...

Sometimes the touch screen, mouse, and keyboard are all non-functional. They are certainly never functional before windows boots. Does this information help narrow it down?
