I have a Dell Inspiron 1100 that I am trying to fix for a friend. The laptop wont boot as if the battery is not charged and her dog ate the power cord. I have a power cord from my old dell that fits it but when I plug it in, the Power light and Battery light repeatedly flash simultaneously and the laptop is unresponsive. I thought maybe the battery was bad so I removed it and plugged the power cord back in, but it still did not respond to powering on and the lights still flashed. Any idea of what the problem could be and how i could fix it? The power output of my old cord may be different from what the laptop needs for input, but I am not sure as the output label is scratched off. If they were different, is this the response i wiould get from the flashing lights?
