DELL PRECISION M6800 - problem after BIOS upgrade to A21 version.

The BIOS was upgraded from A19 to A21. Computer works properly, but I can't enter into BIOS setup. After push F2 key the screen is black (no backlight), the fan works and that's all. After push Esc key computer restarts. After downgrade to A19 version BIOS works correct - it's possible to enter BIOS setup.

Has anyone that problem after upgrade to A21 version?

Best regards

Actualisation:
The screen of BIOS setup is available only on external monitor (connected to VGA port) - when I switch Fn + F8.
The Precision M6800 screen is black in setup BIOS mode (F2) and boot choosing menu (F12).
I've got NVIDIA Quadro K4100M graphics card.

Hi Krakers,

Do you remember how long does it take to update your BIOS? Mine freeze for half hour at 0% and I don't like it.. Not sure if I should power down the system when it says I shouldn't 😕

It looks like BIOS A21 is no longer available. 

I posted about this 20 minutes ago and now my prior post is gone, but at least I got to keep my Bronze badge upgrade.  Scratching my head...
