2. Performance & Stability

• Fix for random "WHEA_UNCORRECTABLE_ERROR" when resuming from sleep.
• Improved eMMC storage detection – no more boot failures after power loss.
• Reduced DPC latency for Realtek audio and Wi-Fi chipsets.

4. Fan Curve Optimization

• The fan now spins up earlier at 55°C instead of 70°C, preventing sudden thermal spikes.

7. Risks & Warnings

• ⚠️ Never interrupt power during update.
• ⚠️ Do not force restart unless frozen for >30 minutes.
• ⚠️ Verify file checksum if provided by manufacturer.
• ⚠️ Some laptops require battery ≥30% + AC adapter connected.

You CAN SKIP the update if:

• Your system is running perfectly stable on an older BIOS.
• You use Linux (the update mainly benefits Windows ACPI and TPM).
• Your laptop is a secondary device not connected to the internet (security patches irrelevant).
