Hi there! I have a Dell Inspiron n4010, and recently my speakers stopped working. At first, it was just one of them, but later the other stopped working too. Everything in the OS seems to be right, the drivers are installed, etc... So I decided to open it so I could see if the connection on the motherboard is alright. And they were, so couldn't solve that. Anyway, the big problem came later. When I plugged the three ribbons attached from the top panel to the motherboard (one for the powering button, another one for the keyboard, and the last one for the trackpad), and put all the screws back in, the laptop didnt boot up. So after playing around a bit to try different possibilities, I realized that is only when I connect the trackpad ribbon that the computer doesn't boot. If it's unplugged, there is no problem. Searching for a solution I found this on another post on /vb/topic37680 (Add techspot.com at the beginning and .html at the end, cause I cannot post links). But that works for a different model, and implies breaking a sensor, which I'd rather not doing. So I would like to know if anyone knows the solution to this, or if there is anybody out there with the same problem and had success fixing it. Thanks and regards!
