Re: hp 450 g7
You have done [COLOR="DarkRed"]excellent job[/COLOR]. Again many many thanks for your effort. Now there is no more "[B]Power-On Authentication[/B]". Every function running perfectly.
Both Main and Backup BIOS had been re-written as your instruction. I did one more thing, made a BIOS backup on pen-drive from HP's site. Also plug-in at the same time for extra caution.
So [B]HP Probook 450 G7[/B] need to rewrite both BIOS to remove "[B]Power-On Authentication[/B]".
Appreciating your effort....
