Adjusting system preferences after a hard drive failure
Adjusting system preferences after a hard drive failure
I've set up a Dell XPS 9510 with four distinct motherboards, including two for power rail issues which appear fixed now. Unfortunately, Bluetooth is turned off in the BIOS, and it doesn't seem to be enabled despite being previously selected during service tag programming. I understand this might have been an error made twice, or perhaps once disabled now it's locked by the hard drive. Windows hasn't been reinstalled, and everything else functions properly.
The BIOS configuration remains unchanged. To verify, disconnect the hard drive, restart the BIOS, and observe no differences.
On HP laptops, a backup BIOS file is stored on the boot drive, which works well when the device allows BIOS flashback, though in cases requiring it, the hardware didn’t support that feature.
It's completely feasible, though unless you attempt to load the save file yourself, it won't choose to load it automatically.
It's quite intriguing. I wasn't expecting a subroutine to detect corrupted BIOS, given how uncommon it seems. Still, for the person asking, disconnecting the hard drive would effectively block the system and would clearly indicate whether the BIOS was removed from the drive (I'm skeptical about that happening).
