Hi.

I have a same problem with my ProBook 450 G3.

BIOS recovery not work at all (Did you tried it???).

If you know what solder is and know how to use it:

Open your laptop and take your motherboard out. Find motherboard model (something like DA0X63MB6H1 Rev. H).

Go to eBay and use search by motherboard name and/or model name something like 'bios ProBook 450 G3' or 'bios DA0X63MB6H1', try different combinations.

You'll find BIOS chip for your model. If not, write to seller, 99% he/she have your version also. When you'll receive it, you need to change broken chip by new one. PROFIT!

Or go to Service Center if you can't do that itself.

Best wishes,

IT-Velho

NO.

You can't flash it using USB drive(also DVD), if BIOS recovery doesn't work.

Solution is in my first post.
