I am in possession of a Dell Inspiron 1440, and on the built in keyboard only certain keys work (Fine with USB keyboard). I took it apart and used some compressed air to clean it, and then when I reconnected the Acer ONE Netbook 531 (Black) Keyboard , some of the keys were still not working, but they were different keys. For instance the A key worked fine before I took the computer apart, but is now disfunctional, while the X key currently works, but didn't before.
I am not totally sure what this means, whether its the ribbon cable, motherboard, or the notebook itself, and I would love some kind of confirmation on which one is causing the problem is such a thing is available.
Also, I had never taken the computer apart before the keyboard broke the first time around if that help. Thank you for your time
