I initiated a BIOS update using Inspiron_3452_3552_4.4.0.exe from within Windows 10. The system rebooted and has been stuck on the 'Flashing...' screen for over 8hrs now. See image below.
I'm fearful of forcing a power cycle and bricking the system.... but I'm not sure where else to go with it at this point.
Advice/guidance would be greatly appreciated!
