Troubleshooting - Stuck on ASUS/ROG Logo Screen During Boot

If your device is stuck at the ASUS logo screen, try forcefully shutting down the device and then restarting it. Sometimes, this issue is temporary.

Press and hold the power button until the power indicator turns off to shut down the device. After a few seconds, restart the device.

• Disconnect all external devices, including the keyboard, mouse, external hard drives, printers, any optical discs in the CD/DVD drive, and any adapter cards in card readers, and so on.   
  Note: Also, remove any external monitors. If it's a desktop, connect to an external monitor to ensure the computer can boot properly and display a screen.
• Update the BIOS to the latest version, here you can learn more about How to update the BIOS using EZ Flash. (For desktops, refer to ASUS Motherboard EZ Flash 3 instructions.)   
  Download the BIOS file for the problematic device from the ASUS support site on another computer and place it on an external storage device (USB flash drive or external hard drive) if necessary. If you don't have another computer or external storage, or if the BIOS is already up-to-date, you can skip this step.

Perform an Embedded Controller (EC Reset) or Real-Time Clock (RTC) reset to restore the hardware in your device to its default state. You can refer to the following articles to understand how to clear it:

Question 1: Why does the ASUS/ROG logo screen display a 「Back Cover was Opened」 warning? How can I resolve this? 

Answer 1: Certain notebooks equipped with an Ambient Light Sensor (ALS) will record when the bottom cover has been opened and will remind you the first time you power on the device after properly reattaching the bottom cover.

Note: The Ambient Light Sensor is a new design feature for system power-off protection. When the back cover is removed, exposing the sensor to light, the system will automatically cut off the power to activate the protection mechanism.

If you see this prompt, you can simply press the power button to shut down the computer, then press it again to start up and enter the system as usual.

Alternatively, you can press 「Ctrl + Alt + Del」 on the keyboard to restart the computer and enter the system directly.
