The last time when my computer shutdown was a power failure. Now some keys are automatically being pressed when I type something.

The last thing I did to keyboard setting was adding a keyboard layout (on Ubuntu).

What is happening

Whenever I press c, xc is writeen

s gives me sd d gives me sd

e gives me we

2 gives me 23, So when I want @ it gives me @# 3 gives me 23

Pressing CAPS Lock gives me F3 and vice-versa.

All other key are either working fine or I don't use them.

I have two operating system Ubuntu and Windows, I use Windows very less and found this problem on Ubuntu, but as soon as I logged in to Windows (for checking) then I found that Windows has the same problem.

Effects on my life

  • This starts form the time of login, even I have problem in typing my password.
  • Whenever I try to save any webpage, it is bookmarked automatically.
  • Whenever I copy, it is cut automatically.
  • I have to spend more than half of time correcting what I have typed.

Note: Typing thisd quwesdtion wasd rweally a big pain to mwe.

It seems like a hardware issue to me. I've had this several times in the past, and just replaced the keyboard. It could just be a piece of debris on one of the tracks. Do you have a spare around to check?

Will cleaning the circuit board (which is made up of transparent material) will work? – Santosh Kumar Jul 11 '12 at 15:08
Which keyboard is it? It should work, but you need to isolate this as the problem first. – Diamond Jul 11 '12 at 15:12
its SSD-KB-806 – Santosh Kumar Jul 11 '12 at 15:37
Did you get a chance to try another? – Diamond Jul 12 '12 at 9:02
I have repaired.. Thanks by the way! – Santosh Kumar Jul 14 '12 at 3:33

Looks like a broken keyboard. You need to connect another keyboard to your computer and check if it works OR connect this keyboard to another computer or laptop and check if it shows the same problem.

One thing I forgot to mention that a few months ago my drink was poured into the keyboard, after a 2-3 days my keyboard became home of a group of ants.

For getting rid from that I opened up my keyboard and cleaned it well, and finally sprayed an (liquid) ant repellent inside and outside of keyboard. I cleaned the excessive repellent as well, and screwed it up.

But I forgot that that transparent circuit board has three layers. And I just cleaned the outer layers leaving two layers wet which was doing short circuit.

In my case cleaning that liquid was the answer which was doing a short circuit I think. Now my keyboard it working fine like before. But one thing I'm still not getting is why it didn't just happened when I sprayed the repellent.
