flashed the file, current draw was 800-850mA. after disabling onboard ram it can display but, cpu temperature read 0^oC in bios screen, no response to power button press when using only battery (battery voltage at 8.4V) but it can charge the battery & read current capacity. processor used is intel core i3 gen 11 with intel graphic. still searching another bios 😑

Look for a QR code next to the CPU. If the model on the QR says X415EA then the F1 asus service bios posted above is the only one you need, look for a hardware problem.
