Hello gays

I have an HP 15 with mainboard LA-D704 is not turn on at all.
19v in is present
Acok is 3,3v
Acdet is 2.5v
ADP_ID is 1.75v
EC_ACIN is 3.2V
VCIN0_PH is 2,7v
EC_RST# is 3.25V

in the schematic it should give EC_ON to start the 5/3v always to start all the section but it not giving this signal unfortunately this line is not shorted to ground i have replace the i\O and the charging IC and 5/3v no change.
i thing i have one missing signal on i/o chip if any one can give an idea to solve the problem.
it is an HP 15-ay094nd reflash the bios also no change, if any one have an EC dump i can try to reflash it maybe will help.
When insert the battery is charging and it light orange.
