I have downloaded the new BIOS, Version A31 from the Dell website for my Inspiron 5150, Windows XP and when I launch it, I get an error message "running on an unsupported system."  What's the deal?  It clearly states on the download page that Windows XP is supported and my system information was  used to filter the downloads.  Please help.

By the way, I need this BIOS upgrade because it will supposedly fix the battery charge problem referred to in the BIOS upgrade description.  Please help in this regard as well if you have contrary information.

Thanks!
