I have a real wierd keyboard issue, Im using a Dell Inspiron 1420, for almost 2 years, updated the HD, and the RAM, so it´ll being working nice, until the day before yesterday. The problem started like this. I started the system and asked me to select the prompt device, never done that before -I know you can configure it, but I did not mess with that -.
So all goes Ok and then I find out that some number keys didnt respond, from 1-4 <that, I could type since there´s also a Fn key that allows me to type them using the proper key <Fn+j, Fn+k, Fn+l and Fn+u> respectively, and the numbers from seven to nine, that I could type them using the on screen keyboard. So I thought it was a simple issue, but as I continued working, some other keys began to open random programs <like the one´s in the quick access bar o another random programs>, then the systems locks off by itself, locking more keys, so its impossible to log on again. Lately, I found out that switching the user resolves this issue, but the numerical issue is not solved. Because Im out of the warranty time, I sent the computer to a technician, he firstly tried to change the keyboard membrane, not a change was made with the new keyboard membrane.
I found the same problem posted in here Keyboard Virus? BIOS Virus? - TechSpot OpenBoards, but they don´t seem to find an answer for it.
I run several antivirus and anti-spyware programs in my computer, none of them had found any threat. I also checked if this problem was a Windows seven issue, loading a free Linux OS disc, and found out the same problem. What should I do? Change of motherboard? :cry:

Hi megapaco, welcome to the forums
The technician changed the membrane, but not the keyboard, right? Have you tried a completely different one? I think yours might have gone bad, the electronics, not only the membrane. Is it a wired or wireless keyboard?

thanks for the reply, yup, he changed the keyboard membrane. Its the laptop keyboard. Ill try with an external USB keyboard, anyway... that could explain the nonsense keyboard pattern, because I forgot to tell that whenever it starts with this nonsense it sometimes happen that some numbers of that ¨black list¨appear instantly in some text based application <word processor or instant message service>. Then the mess begins...
