For any out of warranty "but still working" system, I would never install a BIOS update. Your warranty expired 22 months ago. A failed BIOS update will break the motherboard. BIOS 1.1.27 is not posted. None of the later BIOS added any hardware fixes.[IMAGE]
Where do I find 1.1.27 if that must be downloaded?
XPS 8930, still on Bios 1.1.26, haven't been able to update since
