Hi, I have a Probook 4520s and I want to enter the bios but it says Administrator was locked with a password, as I see in the forum I know that you can provide me the unlock code/password Adminisitrator for my Notebook, I will give to you all the data you need, thanks for your time and patience, Regards Juan Pablo
Probook 4520s
SERIAL: (removed content)

Hi,
Unfortunately, business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.
If you Contact HP Business support they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.
