Hi, im having a problem with my Dell Inspiron 5490 AIO. Its not touch screen, my problem is that when i press on button, nothing happens, ive looked at connection and there is a light on ( green) on power box. Ive tried unplugging the computer and leaving it for an hour or so but nothing, this is my first Dell. Any help, much appreciated. Thanks in advance
