Keyboard pressing space key by itself

[Kd4lif3]

So I started up my pc today and I figured I’d play a little bit of BF4 before my friends got on. Once I got in game I found myself jumping inexplicably. I thought my space key was jammed but this wasn’t the case as it moved freely. I proceeded to restart my pc and open a search bar to see if the space bar issue persisted and sure enough it did. I took off my key cap and the plunger to make sure nothing was jammed and it does not appear that it is. Opening a keyboard testing website shows that the key will be normal for a few seconds before looking as if it is being spammed with increasing frequency before it stops being pressed just to start up again a moment later. I have removed the keyboard from the devices section of settings and I have updated drivers on device manager but to no avail. I’ve tried different USB ports and still nothing new. I don’t see any strange programs running in task manager and the keyboard was functioning fine just last night, I hadn’t thouched it since then. Any suggestions? In the meantime I think I will tear it down and make sure there is not anything stuck on the contact pads under the rubber dome.

Don’t think so. I don’t have any remote control software on my pc and like I said, it was working just 8hours ago.

Edit: Nothing is typed when the keyboard is not plugged in to it cant be anything external besides the keyboard itself or some software interaction with the keyboard.

If I were you I would try booting without it plugged in, and using a different USB port. That probably won't do anything but you might learn something.

Probably the right plan of action.

Rubber domes have a limited lifespan.  It’s why people spend so much on mechanical keyboards.

Keyboard might just be worn out.  If it’s mechanical fix or replacement of switch might be needed.

Not sure exactly what could be broken with they key. The dome is intact and there is nothing on the traces underneath. Might be time for a new keyboard anyway but I really don’t feel like spending that kind of money if I don’t need to. Also there is too much of a pattern to the button pressing and giving it a smack has no impact on the pattern so I highly doubt it is hardware.

There is no way it is a key issue at this point. I have physically disconnected the control board from the dome layer so that no key strokes can be registered and somehow the space key is still being registered on screen. Disconnecting the keyboard altogether stops this so this tells me that it is a driver issue of some variety, I just do not know how to fix it.

Yeah.  It’s totally not the keyboard then.  Weird. For a keystroke to register the correct code has to be sent.  This error isn’t just sending a random jolt, it’s sending the code.  Makes me curious what the code is.  If space is one number it could be just something being wonky.
