Hi,
Please do try these troubleshooting steps that may help in resolving the issue.
- Do a hard reset first, unplug the AC adapter then press and hold the power button for 20 seconds. See if the laptop will boot up after doing these steps.
- Next is to test the AC adapter if it's supplying enough voltage to the laptop to even charge or power it on.
- Try another AC adapter, see if it's just an issue with your charger.
- Lastly, is to contact Asus Support for a repair if all these doesn't work that is if it's still under the factory warranty.
