Hi,

Please do try these steps:
- Hard Reset, remove the battery and the AC adapter then press and hold the power button for around 20 secs. Put everything back together and see if it power on.
- If Hard Reset doesn't work reset the RAM, remove the RAM for couple of seconds then put it back together then power it on again.
- Lastly try hooking up an external monitor just to see if there's something wrong with the LCD display.
- Worst case is the motherboard might be faulty already if all these doesn't work
- If the laptop is still under factory warranty please do call the manufacturer since it might need a repair.
