  • Maker recommends a BIOS update
  • New CPU not supported
  • Stability or security fix listed

Step by step

  1. Ask: does the release note fix a problem you have, add support you need, or patch a security issue? If not, it's fine to wait.
  2. Find your exact model and current BIOS version (Start › System Information › BIOS Version/Date).
  3. Use the maker's tool (Dell, HP, Lenovo, ASUS, Acer updaters, or the motherboard maker's utility).
  4. Back up files and save your BitLocker key. Suspend BitLocker: Control Panel › BitLocker › Suspend protection.
  5. Close all apps, plug in power, and start the update. Don't touch the PC until it finishes and reboots.
  6. After it boots, resume BitLocker if it didn't automatically.
