Hi,
Please do try these other troubleshooting steps that may help.
If there are lights on your laptop and the fans are spinning.
- Reseat the RAM first, take them off for couple of seconds then put them back in making sure that they are seated properly into each slots.
- Test the AC adapter if it's supplying enough voltage to power the laptop.
- Connect an external monitor and see if you'll get any display from it.
If there's no light on the laptop.
- Try another AC adapter.
- Lastly contact Asus support if it's still under a factory warranty for a repair.
