I have a Gateway, model ID49C. I bought it new about 3 years ago but replaced its battery less than a year ago. This phenomenon has been happening for more than a year: When I plug in my computer to charge, sometimes the front power light (orange when charging) and the light for the power button start flashing in unison and the computer stops receiving charge. It immediately stops when I unplug the computer. This only seems to happen when the computer is open -- I can still fully charge it overnight. Lately it's started to happen so often that my computer can barely charge at all from the number of times I have to unplug it. Does anyone know what's going on, or where I could look to find more info? Thanks for your help!
