need clean ME BIOS+EC.
Please help me. The machine does not turn on, so I want to try to reflash the BIOS.

I already asked ME BIOS in the topic "Aspire A315-53G need bios dump". Hoaca338 sent me the BIOS file. I flashed this BIOS, but it did not help. And I have no way to flash the EC file.

I also measured signals on PU801(NCP81218):
SCLK - 1V;
SDIO - 1V;
ALERT# - 0.05V;
SOC_SVID_ALERT# 0.05V (I think it should be 1V). What could be the reason?Leave a comment:

What signals should come to PU801 (Ncp81218) to obtain PWM signal PWM1_2ph?
What should be on PSYS? I have nothing on it
thank you for helping meLeave a comment:

Is it possible that the problem may be in the firmware BIOS?Leave a comment:

The problem is that there was a reflashed BIOS before me. And I do not know for sure whether the reflashed BIOS is the original.
Here is the backup copy of the BIOS....Leave a comment:
