Hi. Asus schematics are rare.

What is the history of this unit ? Power adapter is good ?

Do you see the DCIN voltage?

Review where the DCIN voltage enters the logic board -> then likely 2 mosfets will follow. Check if the same DCIN voltage is present on the mosfet pins.

Post the SMD markings of the mosfets. Also, nearby should be a charger IC that controls these 2 mosfets - what are the markings on the charger IC.

Be very careful when checking the voltages on the mosfet as the power is live and use good meter leads. If not possible, do not proceed.

Instead, we can do resistance measurements to check if the mosfets are good or defective.

Thanks Sir for giving me advice .I will let u know .

Since you're having no display issue, check all coil impedance first.

Then power it on and check if voltage is available on coils,your dc reading should give you a clue. Check DC/DC section, if vcore is not available you can get the datasheet online and check it basic requirements.

Sometimes writing a new bios file will resolve the issue.
