Black screen after changing graphic settings in bios

[party43333]

I brought a new Asus StrixG16   MODEL: G614JJ-N3088WS. I have installed the nvidia graphics drivers but nvidia application does not recognise the nvidia graphics card. It's not visible in device manager also. I had reset the system and tried again but didn't work. While trying i have opened BIOS and changed VGA settings from Intel to Discrete. Now the BIOS doesn't openup to revert the setting and screen remains black. How to solve this?

Please try the following steps: while the laptop is powered off, disconnect all external devices and the power supply. Press and hold the power button for 40 seconds to perform an EC reset. After that, reconnect the power supply and turn on the laptop to check if it can boot into the system normally.

If the issue persists, we recommend taking your laptop to a local service center for further diagnosis. Additionally, if your device was recently purchased and is still within the return period, we suggest contacting the retailer for further assistance to ensure your rights are protected. Thank you!
