Model: AN515-57 Nitro 5

I unlocked the Advanced Bios, and it unlocked me new options. I did not alter any. Windows booted well after I did the process.

But then I went into Bios > Advanced Tab and in "Graphic Mode", I changed it from "MSHybrid" to "dGPU Only", and after restarting, My PC display is a blackscreen.

Keyboars lights up, PC turns on. But no Acer logo, Pressing F2 doesn't boot up Bios.

I cant boot into BIOS at all.

How do I fix this. How to reset this.?

Model: AN515-57 - 15-11400H - RTX 3050

    I believe the warranty has already expired on your laptop, if not bring the laptop to Acer Services in your country to reset BIOS. If you want to try this yourself open the laptop and disconnect the battery. Locate the CMOS module under the battery (round coin sized module with 2 Red and Black twisted wires). Open the module and take out the coin battery, shorten the +/- terminals inside the capsule (battery contacts) with a metal wire or bended paperclip for a few seconds and replace the coin battery with the + sign facing up. Close the CMOS module and connect the battery.

    I know the CMOS battery, but I don't know about the shorting process. Can you send vide a video of this process?

    I looked online and everyone was simply removing the CMOS battery and leaving it for sometime.

    One video even said 10 to 30minutes.

    None of them showed shorting the contacts.

    Can you send me some kind of video for it?

    Don't worry about this "shortening" if the main battery has been disconnected the CMOS shortening routine is absolutely harmless, I would not recommend this if it was not a sound procedure. Check this forum many tried this method, only shortening CMOS would reset BIOS or pressing the CMOS jumper in desktops (same thing). 😉
