Good day! I'm trying to troubleshoot an nm-b242 board. The laptop powers on by default when ac is plugged in. The power button responds and I can turn the laptop off/on, but no display or fan spin. Main rails are present (5valw, 3valw, 1.8valw, vccst, 2.5v_ddr, etc ), even with the laptop turned on. LCD backlight circuit seems ok. The laptop previously had a dead pmic (pu500), which has been replaced and also added pu701 to compensate for the part difference. I'm maybe leaning towards a corrupt bios but I'm not to sure. I'll also add that the fan spins for a seconds then stops. Why could that be? If you need additional info, just ask me. Thank you.
