While blinking the lights, do you hear any sound of the CPU or the motherboard?
I think the problem you might be having is related to a faulty hard drive. If you can't hear anything spinning on your laptop, probably the fan also has gone. Try opening the laptop and put another hard drive if you have one.
The other option is to test the RAM, because it might be damaged too.
I believe, the best thing you can do is to bring your laptop to a technician in order to make the tests.
