Try removing batteries, pressing holding power button to drain power(more time you press the less likely you need to repeat procedure), re test with a good known power adapter. Check old power adapter to see if correct voltage is given, using voltage meter.... if nothing works reseat ram(use 1 module) ,repeat procedure. Or gpu or ram or bios or power problem(these are most likely culprit.)
