Hello Friends,
I have a Latitude 3510 i5 10th generation with the same problem.
Manufacturing mode is always on, not possible service tag entering, canot save.
Fan is always at top speed, keybord is making an annoying "biip" voice at every tab.
Can a friend explain step by step how to make that bios editing please, to fix that problem?
At least, where can i find the place of service tag at hex file, to place it manually?
Thanks in advance....
