I couldn't find the bios to disable the onboard rams. But I found the motherboard schematics and boardview, to disable the onboard rams I removed the RC160 (10K) resistor on the left side of the processor and put it on RC164, and removed the RC161 (10K) resistor and put it on RC165, the onboard rams were disabled. I installed 16GB DDR4 ram in the ram slot and it is working fine now. I am posting it here in case someone else needs it.

Recently, I have started to encounter a problem with Lenovo E15 Gen 2 models not opening. When you try to open the device, it gives a warning sound and does not display an image, when you apply light pressure on the keyboard, the image appears and works for a while, when you turn it off and on, the same thing happens again. Bios was tried, RAM slots were cleaned and soldered to the legs, the problem still persists. There seems to be a problem with the onboard processors, but since Lenovos glue the processor firmly from the sides, the paths are very damaged when removing it. Has anyone encountered...
