Keyboard not working properly - Intermitent issue

[dev1000]

Hi there!

It's my first time posting here on the forum. Hope I can get some help!

I have an intermitent issue on my keyboard. Every now and then when I turn my notebook on some of the Keys don't work.
It happens right from the start when Windows asks me to type my computer password.
When I try to type the password I press some of the Keys on the keyboard and nothing happens.
Even the "Enter" key sometimes is not working. But just some Keys don't work. Other Keys work fine.
Like "A" Works fine and "K" doesn't work.

Also, if I use the virtual keyboard all of the Keys work just fine.
So I'm afraid it's not a vírus as I guess it wouldn't work well that way either.

I already removed and reinstalled the keyword driver again and it didn't fix either.
It also doesn't seem that the keyboard is broken because sometimes it works just fine.

The issue is really intermitent.

Any clues?

 

 

thanks!

this is very minor issue nothing to worry about. And no need of any install software and driver for this problem. you got no help with this. the problem is of your keyboard membrane. you have to changed it, you can do it yourself if you have. its not a thing easily available in market. just go to service center of keyboard and describe your problem.
keyboard membrane is rubber type pad below the keys with lot of wiring in it.

The OP did not say what kind of keyboard he has.
If this is a computer under warranty, he needs to use the warranty.

If the OP or anybody spilled a soft drink on it, it has to be cleansed completely.
If it is a Desktop, he can simply plug in a replacement Keyboard.
Is this a Desktop?

Some regions of the world have unusual keyboards.
Was this computer bought in North America?
If not, where?
