can someone know how to read schematic tell me where i can find the cmos reset on the yoga 900 NM-A411 board. i update bios then black screen, fan spin 100%. i tried everything. novo button, unplug internal battery. i want to see if reset the cmos can save me, before i buy a preprogram bios chip to replace the old bios chip, which i have no experience doing at all. thanks
