Hi @DesiBattle,
Welcome to the HP support community.
Thanks for sharing the details. The error code "i 74452038" you're seeing after three incorrect password attempts on your HP Pavilion x360 indicates that your system is locked with a BIOS or power-on password, and the code is a System Disabled hash used to generate a master unlock key.
⚠️ Important Notes:
- Removing the CMOS (watch) battery no longer clears BIOS passwords on most modern HP laptops, including the Pavilion x360 series.
- HP uses enhanced security that stores the password in non-volatile memory, which is not reset by battery removal.
Please help us with your HP unit serial number or the product number in a private message for further assistance.
