If your Asus laptop no longer turns on, several causes may be responsible for the problem: a faulty charger, a drained battery, a power supply issue, or a defective internal component.
Before considering a repair, here are the essential checks to diagnose why your Asus computer will not start.
1. Check the power supply of the Asus PC
Start by verifying that your computer is receiving power.
Check the power outlet
Make sure your Asus charger is plugged into a working power outlet.
