Locked out of your laptop due to a forgotten BIOS password?

In many machines, the BIOS password is stored within the BIOS firmware. By replacing the original chips with clean, pre-programmed BIOS chips, the password can often be removed.

This makes the chip set a practical solution for:

• Forgotten BIOS passwords
• Locked second-hand laptops
• IT refurbishment and recycling

⚠ Note:

• Not all passwords are stored in the BIOS chips
• Some systems use dedicated security chips
• Results may vary depending on motherboard revision

🔹 FAQ

Q1: Why does this set include 2 different BIOS chips?

Certain motherboard designs utilize a dual-chip / split-BIOS architecture (where the main BIOS code is divided across two separate SPI flash chips). Both chips must be replaced as a pair to ensure complete firmware restoration.

Q2: Are both BIOS chips pre-programmed and ready to install?

Yes. Both chips in this set are fully pre-programmed with their respective firmware files and verified before shipping.

Q3: How do I know which chip goes to which position on the motherboard?

The chips are clearly labeled to correspond with their respective motherboard designations (e.g., BIOS 1 / BIOS 2). Please double-check chip markings and board locations before soldering.

Q4: Can this BIOS chip set unlock or remove the BIOS password?

Yes — in many cases. Replacing the original chips with clean, pre-programmed firmware will remove passwords stored within the BIOS firmware.

Q5: Do I need soldering tools?

Yes. Professional soldering equipment (hot air rework station, soldering iron, flux, solder) and technician-level skills are required.

Q6: What if it does not fix the issue?

If the issue is caused by physical hardware faults (PCH, CPU, EC, or power circuit issues), replacing the BIOS chips alone will not resolve it.
