Hello. Lenovo 710-11isk NM-A771,SR2ER processor with built-in hub and video. When connected from a laboratory power supply, the current consumption rises to 300mA, after 10-20 seconds it drops to 250mA. It may stay like this for a long time, or it may fall to 10mA. The display is connected to the board, voltages are present on the processor PWM, except +CPU_VCCGT video core power supply (no PWM signal) I replaced the NCP81206 controller, but it did not change anything. All voltages are normal except +CPU_VCCGT. I also replaced the PWM charge controller because there is no signal from it to the PSYS_CPU processor PWM. It didn't change anything. I also flashed the BIOS with a clean ME region. I understand that the signal rises under load, but I have no other display to check. If anyone had a similar problem, please let me know. Thank you
