            Do you guys have the U7103 bin? U7201 (TPS65994) TBTA_VBUS20 output is on a loop from 3v - 5v and drops to 0v, I suspect the firmware of the PD chip is corrupted, but here is the backup

              Check your CPU , according to the laptop configuration based on the service tag your CPU is an i5-1135G7 Tiger Lake.

                    Dell Latitude 5400 Chromebook UEFI bios

                    Hi there masters, recently i got a dell 5400 chromebook and wanted to install windows, i searched the internet and i found out other people also wanting a UEFI bios for this model, i searched there is a R/W legacy, but there are bugs like keyboard/trackpad not working, and hard to install.

                    so i decided to try to port one, this bios is based on dell 5400 windows version, i am testing this bios for a week now an found only a little to no bug at all in windows 10, or only a minor issue
                    in windows 11 sound driver compatibility, but overall its ok, for me i can deal with it, 😅😅😅...
