        You will need an SPI bios programmer to make a backup of the chip.The chip is in a WSON8 package,so you will need to desolder it first ,then put it into a WSON8 adapter or alternatively use a WSON8 pogo adapter (unreliable YMMV) .Then read the chip a few times,check to make sure you`ve made a good backup, then post it here inside a zip or rar attachment and also post the laptop serial number.

        1. How to dump and flash
        1.1. BIOS

          Thank you. So basically, RCUnlocker or any other tool can't bypass/reset the Administrator BIOS password without removing the chip?

            "or alternatively use a WSON8 pogo adapter (unreliable YMMV)" .The most reliable way is to desolder the chip using a hot air station.
