I also had this problem at the beginning, when I installed a thin SODIMM plate, there were 4 white flashes and 2 orange flashes, and the power button indicator disappeared. This is not a sign of a device malfunction, so do not worry about the thickness of the plate. Reinstall the CAMM, start the laptop, then turn it off through the "START" menu, and then remove the battery. After installing the SODIMM, make sure that the pressure plate is evenly secured without any distortion, and that each bolt is tightened in turn with a small step. I changed the CAMM to SODIMM several times, and it started. SODIMM initialization takes a few minutes, and if the initialization is successful, the button indicator should not turn off. Be very careful with the contact plate, as the contact may fall out if it is touched with any object.
