HP Elite Dragonfly G2 Notebook PC (25W59AV)
Microsoft Windows 11

i have a DRAGONFLY G2 11Gen core i7 512ssd  and 16GB RAMi previously had a BIOS version HP T90 Ver. 01.10.01(2021) , and i updated recently to the latest 2025 version , and it caused severe post boot lag , and battery management not working , and the fans are too loud after  booting , and the post boot lags last like 40 to 60 seconds which is so annoying considering that my DRAGONFLY G2 11Gen core i7 512ssd  and 16GB RAM never did that UNTIL the BIOS update. I was requesting for a rollback , please provide the 2021 version for the DRAGONFLY G2 NOTEBOOK pc

Hi @Alihat 

You should update to the latest BIOS version 01.23.00 Rev.A (Jan 16, 2026) from the HP Support page for your HP Dragonfly G2. This release supersedes earlier firmware and may address the post-boot lag, battery reporting, and fan behavior you’re seeing
