Keyboard Malfunction

I'm a computer tech working on a customers dell inspiron 6000 laptop. When you try and type it will input an additional key(s) for each key pressed. For example, type d and d3 comes up. Some keys work as expected but the ones that don't are consistent. I figured it was the keyboard so ordered another from dell installed it and got the exact same results. I saw a post on another site to tighten case screws, did that to no avail. It also does not appear to be software, because I boot the UBCD4win (bootable windows on a cd) and get the same results. Anyone have any ideas what's wrong with this thing?

    Just curious, did the new keyboard come with a new cable to attach to the board? Have you pulled the cable from the board and reseated it?

    Yes to both. It did come with the cable attached and plugs into the port directly on the motherboard. And yes it has been reseated several times

    tjk176,
     
    Have you run the keyboard test from the Dell Diagnostics?
     
    It seems unlikely that two keyboards would have the same problem, possible, but unlikely.  Unfortunately, the only other explanation that I have is a failing motherboard.

    I'm having the same issue. It just started like 2 days ago. Everytime I press y, y6 is punched instead and t=t4. My backspace button acts like the windows button and my tab button isnt working either. Any ideas would be great help! thanks

    Never mind errrbody! I solved it..
    NO NEED TO BUY A NEW KEYBOARD AT ALL
     
    All you have to do is clean out the bottom of your keyboard. It's easy, find the intructions on how to take you're keyboard apart (the manual) on the dell website and then clean out the dust/crums/dirt that is under your keyboard. Also, try Unplugg the ribbon from the motherboard and plug it back in.. it will re-seat the cable with the motherboard.
     
    I just blew hard at the keyboard once I removed it from the case, and then unplugged and replugged the ribbon from the motherboard. I put things back together and -just like that, it worked again, normally!
     
    Im glad I didnt buy another keyboard, Ive read on other forums how users with the same problem go out and buy another keyboard and their problem still persists... so make sure to clean out the slot where the ribbon attaches and things should work again beautifully.
     
    Browse the web some more and you'll read that cleaning out the keyboard and replugging it back into the motherboard has solved the problem for many people!

    Hi there!

     

    I got my laptop an INSPIRON 1525 just 14 days back, and to my horror, on the very second day, I found out that my keyboard was malfunctioning. After that I figured out that some other keys were not working properly too, KEY 2@=2", ' "='@, 3#=3 and the pound sign, \|=\#... In these 14 days, I have figured this much, dunno wht's in store for the coming days.

     

    But after reading your thread, I got a bit releived. But I am not an expert with hardware stuff.... I have also informed Dell. Should I let them do what you have done to rectify your erring keyboard?

    Hi,

     

    It's actually  very easy to open up your pc to make sure that your keyboard is properly installed. When I was having keyboard problems, I was looking to have it sent back to dell but luckily I didn't. Open up your laptop using instructions found here http://support.dell.com/support/edocs/systems/ins1525/en/SM/index.htm and all I would do is unplug the keyboard from the motherboard and plug it back in. I hope this works for you as it did for me.
