My brother gives me hcl laptop but system ask for HDD password,any bdy khow how it break... :confused:

If your brother actually gave it to you, you would have asked him. I don't think there is a way to bypass a hard drive password, this is a usual something companies install on their laptops and depending how it was set up you might not even be able to format it without the password.

Why doesn't your brother tell you the password?
