Please help identify these components in granger2-6050A3024001 MB

Hello friends, I have a board without schematics. granger2-6050A3024001. I have 3 and 5 volts. But there is a very low consumption. I want to identify U472, to be a RAM memory source. When pressing the button, there is no activation. The coil does not show anything abnormal, although the 5 volts part has an impedance of 33.2 ohms; I consider this voltage optional because it is always activated.
