I need to update my BIOS to the latest compatible version, but my systems Serial Number and SNID are not recognized on the Acer update website.
S/N: PTSFS02001XXXX
SNID: XXXXX

I have an Acer Aspire X3400G-U4802 and I see two Bios updates available (P01-B2 and P01-B3 both with the same date), but I want to be sure that installing the P01.B3 is correct so I don't brick my computer. I tried the update tool, but its showing no updates for a newly installed operating system, so I kind of doubt that it is working correctly. My current bios is version is P01-B02.

Any help is really appreciated

To add to that, my current bios version is not P01-B02, but instead should be P01-B2. The release date is listed as 06/01/2010.
