Here are some troubleshooting steps to try:
1. Basic Power Reset (EC Reset) – Try This First!
Since your laptop drained completely, it may need an EC (Embedded Controller) reset:
1. Unplug the charger and disconnect any peripherals (USB, external monitor, etc.).
2. Press and hold the power button for 30-60 seconds.
3. Release the button, then plug in the charger and wait 10-15 minutes before trying to turn it on again.
2. Check the Charger & Charging Port
Try a different outlet to rule out power issues.
If possible, test with another compatible charger (ROG laptops are sensitive to power supply quality).
Inspect the charging port for dust or damage—sometimes, debris prevents proper contact.
3. Check for Battery or Power Delivery Issues
When you plug in the charger, does the charging light stay on?
If yes, but the laptop won’t turn on, it could be a battery issue.
If the light turns off again, there might be a short circuit or power delivery problem.
Try turning it on without the battery (if removable) by plugging in the charger directly.
4. Try Booting Without Peripherals
Disconnect any external devices (USB drives, headphones, HDMI cables, etc.) and try again.
If you recently installed new RAM or an SSD, try removing it and re-seating the original components.
5. Check for Signs of Life
Do you hear any fan noise, keyboard backlight, or a faint screen glow?
If the laptop turns on but has no display, try connecting an external monitor to see if the issue is with the screen.
6. ROG-Specific Key Combo to Force Power On
Some ASUS ROG laptops have a key combination to force power on:
1. Press and hold the power button.
2. While holding power, press and hold F2 + F3 keys for about 30 seconds.
3. Release and try turning it on normally.
7. If Nothing Works
If none of these steps work, it might be a motherboard power issue (e.g., a faulty MOSFET, capacitor, or charging circuit failure). If your laptop is still
under warranty, you should contact ASUS support for repair options.
