I am unable to update my Alienware M17xR3 Bios.

Windows 7 Professional SP1, 64 Bit. (I did a fresh install of Windows 7 because I could not update the BIOS in Windows 10 Pro 64 Bit).

I get the following Error when trying to update Bios from A04 to A05.
  • phoenix winphlash64 version
    Error Code Error Message
    -100 BCPSYS block signature was not found.
The A05 Bios Flash does not work via bootable USB drive either; it needs to be performed within Windows.
I did "identify" the error via the following guide, however the "fix" or workaround is not provided. ... -guide.pdf

Note, the Battery is an original, recognized in the task bar notification and BIOS, but refuses to charge. I have replaced with a new battery as well.
I am hoping that eventually updating the BIOS to a higher level (A10 or A12) will help me fix the battery charging issue.

Any help is greatly appreciated.
