Surface Pro 4 stuck on "Surface" screen with padlock an red line
Recently found a SP4 in a tech recycle bin, and when i plug it in and power it on it just displays a screen with the word "Surface" and a red line and padlock with no spinning dots, exactly like this:
Now i know the red line and padlock means secure boot is disabled, but it wont boot into either the UEFI or a recovery USB and an Arch Linux USB (that i tested and they worked on my SP3 (that i found in the same bin))
It doesn't look physically broken or like its been taken apart before, it could have liquid damage, im comfortable with trying to open it up but i'd rather not.
Any help is much appreciated! I'd love to fix it but i didnt pay a cent for it (other than buying a $30 charger off amazon) so it doesn't matter too much. I may take it to a Microsoft store tomorrow since they were a great help with my SP2 a couple years ago, but i'd love to do it myself.
Questa è una buona domanda?
