Yes, I know, I only noticed this after soldering the CPU to the motherboard. My mistake for not checking this first. So I thought I'd try using the same region and swapping the BIOS part, and the motherboard started booting, but only up to 250mA. I was hoping someone could help me solve the problem. So I had to replace the CPU again.

Thank you...

Hi everyone,
I'm working on a UX534FTC (ASUS ZenBook) computer that originally had a faulty CPU and PCH. I transplanted a working CPU and PCH from a Lenovo NMC421 motherboard. I verified that the motherboard is fully functional—it boots correctly on the original motherboard.

Now, on the ASUS motherboard, the system briefly powers on (~250 mA) and then shuts down—no POST, no backlight, no fan spinning.

So far, I've tried:

🔧 Flashing a clean ASUS BIOS (UX534FTC_306)
🔧 Flashing the full CSE region from Lenovo to the clean ASUS BIOS
