Turn on the laptop. Step 2: Type any password three times until you see a screen that says "System Disabled" followed by a long number (e.g., 57546233 ). Step 3: Write down that code precisely. Step 4: Use a smartphone to visit a "HP BIOS Unlocker" website (search for "HP laptop BIOS master password generator"). Step 5: Enter the code from your screen into the generator. Step 6: It will produce a master password (usually 5-10 digits). Step 7: Type that master password into the laptop. Note: On some models, you must press Ctrl+Enter rather than just Enter. Success Rate: ~30% (Works on older BIOS versions). Method 2: The CMOS Battery Short (Hardware Reset) While removing the CMOS battery alone won't work, shorting specific pins on the BIOS chip will.
