I have a last question if you don't mind!
Is it going to be a problem if I do a Bios Update via Windows, to the latest version after the installation of this unlocked version?

Thank you very much Vesko356!
Cheers

No, it won't be a problem, you can update to any version you want, including the latest one.

Vesko, an error occurred during update! I haven't wrote the service tag that had before!
What you think, what might be the problem?

Re: Dell Latitude 7400 EDC40 LA-G871P

Vesko, an error occurred during update!

The error is shown on the screen - invalid password. You must input the correct (bios) password, or better remove the password, then update the bios. If you like afterwards you can set the admin password again.

I haven't wrote the service tag that had before!

I didn't get that, explain what you mean.

After the Bios Unlock I've asked you if I could update bios version afterwards to the latest one... You said yes there would be no problem and after that I have downloaded the latest one and during update process, it gave me that error! Isn't supposed to be without password?!

What do you suggest to do?

I didn't get that, explain what you mean.

I was wondering if it's necessary to put the service tag that had before which might explain why it gave me that error!

Once again thanks in advance

Enter the bios, remove the password if you set any, if you didn't set the password everything should be OK (admin password must be cleared with the unlocked bios), check the Service Tag field - must not be empty, if it is ,the STag must be inputted and saved.

At first boot press F2, write the service tag, save & restart. After that at the second boot press Alt+F to exit manufacturing mode. And the fan will slow down.

Hi everybody. Please help me BIOS has late display problem. I have worked with FIT but the problem has not improved. I have flashed many other dump files but not working. With other LA-g871P systems FIT works perfectly.
