Dell XPS 13 7390 bios

[fabyband94]

Good evening, I have a Dell 7390, the power LED turns on for 3 seconds then goes off. I tried another bios found on this forum, it turns on but the display starts to appear after 3 minutes.

cpu i7
service tag FFYPFB3
edp35 la-h931p rev:1 (A00)

I attach the original bios.

I thank anyone who can help me.

With this bios found online, the notebook turns on, but does not see the memory. Furthermore, the service tag should be corrected, is it important?

Dear fabyband94,

Please find attached my working BIOS with NVME support.

I believe you’re experiencing the same issue as I did.
Your BIOS dump doesn’t contain only the BIOS itself; it also includes your laptop’s configuration data.
I manually edited my configuration to correct the NVMe settings in a clean image.

By default, the system boots, but some voltage and PCIe parameters aren’t configured correctly. I went through each setting one by one to ensure they matched my laptop’s original configuration.

You could try using my fixed firmware, where I corrected the NVMe configuration. My NVME drive is now properly detected, and I’m fairly certain it would work for you as well. The service tag doesn’t seem to be particularly important in this case.

For information, I fix many thinks like voltage on some GPIO.
If you open your file using "Intel CSME System Tools v14.0.11-r1," you’ll be able to see your SATA and PCIe configuration details.



My working configuration for nvme

Thank you so much. You solved my problem, everything works perfectly now. Thanks again.
