I stupidly disabled the onboard GPU to see if the dGPU works. to reset the BIOS, it should be clear just to remove the CMOS battery for sometime and replace it and you're good to go. But no, not with me, the stupid unlucky. I removed it for 20 minutes with no results, now I can't access anything. I'm panicking because it is not my PC, what to do? please urgent help!
