|It could be a bad power connection: AC adapter, AC power plug on power supply or on the motherboard; faulty power switch; could be a bad motherboard or other component. |
Unplug it from power, pull out the battery, RAM, any other components that you can - HDD, DVD/CD rom, WiFi adapters, Modem, USB/Flash memory cards and other peripherals (if applicable). Plug the laptop into AC power and try to turn it on to see if there's any life to it. If there is, add back in one thing at a time and test boot each time:
- RAM - inspect RAM slots, blow out with compressed air
- DVD/CD rom
- WiFi adapter
MOOOOooove! OH and you're welcome!
