Hello everyone,

I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.

This is the picture of 3 similar ASUS motherboards, all of them being X555LD...

Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...

I’m troubleshooting an ASUS ROG Strix B660-I Gaming WiFi motherboard and I’m a bit stuck at the BIOS level. What I’ve tried so far

• Attempted to flash the BIOS using the USB BIOS FlashBack (Q-Flash) port with a properly formatted FAT32 USB drive.
• BIOS file downloaded directly from the official ASUS support page.
• Followed the exact FlashBack procedure (correct port, renamed file, standby power only).

Issue:
The FlashBack LED does not blink at all — no activity whatsoever. Further investigation


Because FlashBack didn’t work, I:

• Removed the BIOS SPI IC from
