If removing the battery did not clear the BIOS
password then the jumpers won't either as all they
really do is bypass/short out the battery to kill the
contents of the CMOS/BIOS memory. In this case the
only real way is to call Tech Support and see if they
can/will help you clear it with some type of a software
tool they may have in-hose as Hewlett-Packard does.
