Hello everyone, it may seem like a novice but I can't find the Rom Bios, the one I unsoldered with the data that is silkscreened on the component does not appear any information on the internet and when unsoldering it and placing it in the CH431A or the EZP2019 + it does not detect it at all not even with the 1.8V volt adapter, could you tell me if I am choosing the correct component, I have looked for the Schematic but I can't find it either, it is a JS471 / JS573 Lenovo 15ALC7 Motherboard...
