Updating bios administrator
In yet other cases, the EEPROM chip has to be desoldered and the data in it manually edited using a programmer.
Sometimes it is enough to ground the CLK or DTA line of the I²C (Inter-Integrated Circuit) bus of the EEPROM at the right moment during boot, this requires some precise soldering on SMD parts.
In older computers with battery-backed RAM, removal of the battery and short circuiting the battery input terminals for a while did the job; in some more modern machines this move only resets the real-time clock (RTC).
Some motherboards offer a CMOS-reset jumper or a reset button.
User Password: The user password is also called a system password because it controls access to the entire system.
If the user password is set, the password prompt is displayed before the computer boots up.
The default motherboard BIOS version was dated 3.56 released in Jan/2013 and the latest one we can get from the HP website is v3.57 which was released at July/2013.
I suppose that isnt up to date solution as it uses flash memory for storing password. Than are utilities to reset CMOS, but they didnt worked at all or needed to boot from cd or flash drive. So i was browsing an internet to find a solution but i found nothing. Than i found you can set any date, if u have some problems with that ( up to 2011) and find your pass here This was also tested on another two ASUS notebooks A55C and F751LX. If you download multiple revisions for one model, I suggest you come up with a naming convention so you don't have multiple separate directories to hold one revision.The BIOS (Basic Input/Output System) is critical to the proper operation of your computer.I tested these steps on a Dell Opti Plex 780 SFF (Small Form Factor), Dell Opti Plex 790 SFF, and Dell Opti Plex 3040 MT (Mini-Tower).All systems were running Windows 7 Professional x64 and Windows 10 Pro x64.
