Identify Your Product Correctly "Q78" is often a code printed on the motherboard or associated with a specific BIOS family, but it is not usually the exact model name of the laptop. To find the correct firmware, you need your specific Product Number (p/n) .
How to find it:
Press Windows + R on your keyboard. Type msinfo32 and hit Enter. Look for "System Model" and "System SKU" . Alternatively, look for a sticker on the bottom of your laptop (often inside the battery compartment) for the "Product #".

3. Pre-Installation Checklist (Very Important) Firmware updates carry a risk. If the power cuts out during the update, the motherboard can be "bricked."
✅ Plug in the AC Adapter: Ensure the laptop is charging. Do not rely on battery power. ✅ Close all programs: Save your work and close all open applications. ✅ Do not interrupt: Once the update starts, do not touch the keyboard, mouse, or power button. The screen may go black or beep—this is normal.
