I have a Legion 5 15ACH6 with RTX 3050 ti graphics card (NM-D601 board). Computer charges when plugged into a charger. When power button is pushed, it lights up and stays lit forever. No other action is happening. All voltages needed to start are present: 3.3V, 5V, 1.8V, 0.75V
The EC chip gets 3.3V on many pins, it is not shorted. However, IC chips responsible for generating 2.5V, 1.2V and VCORE are not producing the power due to no signal on the enable pin.
I can, of course, reflash the BIOS chip but I think the EC chip is corrupted. I read somewhere where it was said if the computer is charging and the EC chip gets the right voltage, then it is not corrupted.
Could someone, please weigh in and let me know whether I should try reflashing the bios chip or rather replace the EC chip? I think it's the latter.
