The flash descriptor is missing from your bios backup. Try this one

Re: Probook 450g3 bios

Hold down left + right arrow keys and power up, there may be a message then on screen about the flash descriptor being unlocked,then you can make a backup or flash the bios at post #3 with Flash Programming Tool.The flash descriptor will lock again at shutdown/reboot.If it doesn`t work use a bios programmer,desolder or use a sop8 clip .

Re: Probook 450g3 bios

You can`t backup that part of the bios with universal bios toolkit ,because the flash descriptor part of the bios is locked. Try what i said at post #5 ,if that doesn`t work,try holding down the Win key and l + r buttons while powering up. If nothing works use a bios programmer ,flash the bios at post #3 or #6 .

Re: Probook 450g3 bios

First dump post #3 no display,second one post #6 only 7 blinks,machine does not power on.my original dump from locked machine was done by rt809f bios programmer.i am so confused,i have four other machines waiting.

Re: Probook 450g3 bios

Your backup is definitely not proper. I too use RT809F programmer but i never get such broken backup. Btw, You try this bios and post result.
