Dell Precision 3660 - BIOS Update 1.2.48 - Fails


i have this new Precision 3660 with Windows 10.

I can´t update the latest BIOS, the BIOS Update fails with this error message.



The Remote BIOS Update can´t find any new BIOS online.

Is there any fix for this Problem?

Let Dell scan your new computer to see if you even need a bios update--Go to

use the Dell SupportAssist app to do the update.

If you ask a Dell technician, they definitely don't recommend you to update the BIOS unless the computer is malfunctioning, even if there is an updateable version.
I think it's safest to restore the old version.
