Asus Zenbook Pro Duo OLED UX8402ZE

[draxem]

Hello guys,

I'm going crazy with this laptop that i have. It's an 12th gen i9 with 3050Ti graphics and 32GB ram (soldered on board). When i plug in charger, fans go full speed and small oled screen lights, main screen has no light. When charger is removed, it power off. When charger plugged and power button pressed long, laptop restarts but it does exact same thing as mentioned before.

I have tried cleaning ME with the dump file that i have, tried other bios dump file... and a lot of combinations more but i am not able to flash a working bios to laptop (i hope is only bios fault and not other thing...).

I'll add my bios dump file, maybe any of you can help me with a working bios for this model, or repair my dump file.



thanks in advance.

post serial no. motherboard ID and photo with QR sticker from motherboard. All necessary to identify what bios you need for your specific machine.

the bios backup image you posted is a cleaned ME image, not original bios. DMI is in MFS partition from ME_Region, so take DMI from there, from original bios.

I'm a bit lost here. So maybe somebody messed up with the bios already... (it came in a lot with more products).

I'll investigate the DMI thing but i'm not familiar with that. If i flash this bios file that you gave, it should work?

Thanks in advance.

I've flashed the bios image that you gave and is doing exact same thing, fan speed fast and no image on screen.

I really don't know how to go further with this thing...
