Purchased 2018 as replacements in case of failure of other HP laptops. Pulled fresh from shelf Apr 2025.
Worked OK until BIOS update.
Attempted fix with options within BIOS setup, including F11.
Last try for fix was power on while holding Win & B keys. Received predicted beep, no screen.
Power button now has no effect.
