I installed a fresh MS Windows 10 and after that SupportAssist on a brand new Dell Precision 7540. Hoping to turn into a dual boot configuration.

SupportAssist started a bios update and this bios update got stuck somehow. The screen shows.

• Updating your firmware
• Do not power down your system
• Flash progress 100%
• Updating System BIOS with Bios Guard

I cannot turn it off. I can press power down for minutes, nothing happens. The battery cannot be removed I think without opening the system.

Is this brand new laptop dead meat now? I only had it for a few days. Why does Dell do Bios updates this  way? This doesn't make sense. Why would you suggest BIOS updates that are untested and not working?
