Notebook model Exper W25HP no RSMRST#

Hi
Notebook model Exper W25HP, Motherboard 6-71-W25P0-D02B.GP
Problem: 3.3v and 5v were missing, one diode (vin) was replaced. Stand by started working. But now there is no RSMRST # signal. When an extra 3.3v is given to the RSMRST # pin on the SIO, for example, when I make a short circuit with 3.3v next to it, the device starts and displays the screen. But when I press the power button there is no start. Please can you help me, thank you.
by the way, there is no flash eprom 1st pin 3.3v, there is only 1.85v. Is this normal, can it be a flash eprom problem?

EC won't lift RSMRST until some conditions are met. Which conditions depends on the board and the EC, but generally clock, standby voltages, SPI response from the flash. I would double check the CMOS battery voltage to eliminate funnies.

1.8V flash is definitely a thing, but whether this is appropriate here or not should be determined by the chip that's actually installed.
