Most likely thing is a motherboard issue. You can try unplugging battery and wall power, open it and remove the CMOS battery (if there is one in that model), hold in the power button for about 30 seconds, then plug in wall power only and see if it turns on. That looks like a lower end system, most likely will be cheaper to replace it than get a motherboard to fix it.
