Sorry, completely off topic but I am desperate. I have a Compaq Presario 700 series laptop and I need a new AC/DC adaptor. The low voltage lead keeps breaking inside and I have bodged it up for now with a new piece of cable. Anybody know where I can get a new adaptor? PCWorld are as much use as a chocolate teapot! There are lots of different part numbers on it, but the output is 19v, a I have used a Sony 19v one on it , any ideas??
