Z440 workstation bios password

Hello, i need a bios password to access bios options? I have tried jumper settings as stated in the service manual and also removing the battery, nothing!! After 3 wrong attempts it says locked out please restart the system. Can you help please? Thanks

with computer OFF-Put the jumper in clear password position..and start your computer...then enter BIOS...access the settings..

after that turn it off again and put the jumper in original postion

Thank you for the reply, i have done all these steps....

1. Access the jumper:
a. Shut down the operating system, turn oƫ the computer and external devices, and then disconnect
the computer power cord and external devices from power outlets.
b. Disconnect any external devices.
c. Verify that the AC power cord is disconnected from the power outlet.
d. Open the workstation.
e. Locate the password header and jumper.
The password header is E49. The password jumper is blue so it can be easily identiƭed.
2. Remove the jumper from pins 1 and 2. Do not lose the jumper.
3. Restart the computer:
a. Close the workstation.
b. Reconnect the AC power cord to the power outlet.
c. Turn on the computer and wait for the workstation to display the HP splash screen.
4. Repeat step 1.
5. Replace the jumper on pins 1 and 2.
6. Repeat step 3, except press the F10 key during startup to access Computer Setup (F10) Utility

when i press F10 it asks for a password?
