Good day,
Laptop model: RZ09-03519G11
CPU: i7-10750H
GPU: GTX 1660 Ti
Mainboard: MBPGR5MP6A-AN10, OL510-MB PTV V1.0
Embedded Controller: IT8390E-256, EC flash: 25Q64CSIG

There’s an issue with power-on — the PWRBTN# signal (controlled by the EC) gets stuck. This signal is managed by the EC firmware itself.
If anyone has a working BIOS and EC dump, or could help correct my dump, I’d be very grateful, since I haven’t been able to find one publicly available....
