Ask Lenovo Legion Y530-15ICH not working with battery

[jaudat]

Hello,
if i try pressing power button while the charger is unplug, the laptop does not work, no lights no display, nothing happen.
if i plug the charger and press power button, the laptop start normally, and after that if i try unplug the charger the laptop stay working fine (indicate that the battery is good).

i attached the backup of motherboard Bios
