Hello

I have model AHL50/abl52 LAC710p - ac120ns. It doesn't turn on after connecting the battery. The battery is charging correctly. I remove the battery, restart the bios by pressing the start button for 30 seconds without a charger and it works. I connect the battery, press the start button and it does nothing.
When it is on and I connect the battery, I reset it and it works and detects the battery.
I have measured some voltages according to the schematic and they are correct.​
Can the BIOS be corrupted?...
