RE: XPS9560 Bios 1.2.4 bricking systems
I had the same issue... twice. First time I called support and they just sent me a new device. I figured the first brick was a corrupt download so updated the new machine and... same thing. I tried holding the power button but that did not work. The FN key however worked like a charm. Kind of sad that it did... I was half looking forward to see how many new laptops I could brick in a month before Dell figured it out and took the BIOS down from their site.
