Frequently asked questions

Quick Answers

When should I update the BIOS firmware on Galaxy Book6?

BIOS updates improve hardware stability, patch CPU microcode security vulnerabilities, enhance battery charging efficiency, and optimize thermal fan curves on your Galaxy Book.

How do I safely install this BIOS update on my Galaxy Book?

Connect your notebook to its AC power charger (never update on battery power alone), close all open programs, and run the firmware updater. Do not power off, restart, or close the laptop display lid during the flashing process.

Will updating BIOS firmware erase files on my Galaxy Book6?

No. BIOS updates modify the motherboard UEFI firmware and do not alter your Windows operating system, installed applications, or personal files.
