Yeah, I wonder if there's a solder gap? Is the lcd screen backlight on? Usually you'll get a beep code, though. If you have time to waste, look on Youtube for reflowing a motherboard. It's worked for me several times and it only costs you a thermal paste tube/patch (plus the joy of completely tearing apart your laptop). You might be able to get a mobo cheap online and replace it, instead.
