I was looking at your video for about this kind of Lenovo T14 gen 1 and that PD controller video is very helpful. Thank you mate! I also have a USB Type C power jack problem, one of the VBUS pins is detached from the board and the questions are:

1- Since there are 4 VBUS pins connected together, would be any problem if one of the VBUS is missing?
2- The resistor R6304 it is not giving any ohm value and I think the current it's not flowing through it! Probably damaged from any short circuit..! Could this be the problem that I am not having 20V in the test point TP6301 or at USBC_VBUS20...

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 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...

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


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...

Hello,
does this file works only to the bios with that serial number or to any bios?...
