The latest BIOS version for this Lenovo IdeaCentre 710-25ISH is: FWJY9EUSA.EXE (BIOS version: FWKT9EA dated: 4/22/2019)
Not sure where/why we are being offered this one FWJY47USA.EXE (BIOS version: FWKT47A) with a November 26, 2019 date, which would appear to be newer, but it is definitely wrong. The real date on the one currently offered is: 4/20/2016.
For some reason, a newer BIOS is not readily available on the Lenovo site.
