My question is: is this IC reprogrammable, or do I just need to replace it? It appears to be controllable via I2C or SMBUS, and the main controller should be able to control it, so it probably doesn't need any further programming and should work out of the box. Also in case it's programmableI need to know if there's any kind od ec bios available for this ic and laptop model.

Hey guys, I have an Asus gaming laptop. It arrived with a short circuit on the 20V rail due to a failed attempt to restore the backlight. I resolved the short circuit, but when I connected the charger, the laptop wouldn't turn on. I also noticed overheating on the 3V and 5V power supply. After a few hours of diagnostics, I identified the faulty component: the IT8308FN, it seems to be a GPIO expander for EC. This component got damaged and caused a short circuit on the 3V LDO rail, causing the power supply to overheat due to the overcurrent.
