HP Recommended
Product: Zbook 15
Operating System: Microsoft Windows 10 (64-bit)

My Zbook came with Win 8 which I upgraded to Win 10 trough Microsoft free upgrade offer. A few days ago when I pressed the power button a message poped up saying something like "BIOS identity was rewritten by Embeded Controller due to hash mismatch" (I do not remember precisely), and after 10 seconds it ended up to a blank screen and nothing more. I made many efforts such as entering the BIOS setup screen and restoring the default settings, which did not help. Finally I created a recovery flash as described in HP website and updated the BIOS, and the problem is solved now. Now the question is that will this happen again? And is it possible that HPSureStart feature has been deactivated/uninstalled/whatever when Windows was updated, and if so do I need to do anyting to restore it?
