No power whatsoever, but...

Question

I think I had a power surge in my apartment even though my HP Laptop was plugged into a power strip. Anyway, no power whatsoever. The adaptor showed a light where it was plugged into the computer. And after turning it over and hitting what I thought was the reset...it caused the battery light to continually flash. But that's the most life I've been able to get from it. Any ideas, without having to send it for the $80 estimate?
Thanks
It's an HP Pavillion dv9000 notebook
