Hello. Can you also send me a reset password for my Probook 4510s? The serial number is CNU9477TWK.

Thanks in advance

Hi nikdouv,

 

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.

 

If you Contact HP Business support, they may be able to send you a customised file which you can use at boot to reset the password - the only other method that will work on these machines is to replace the bios chip.

 

Regards,

Do you receive a halt code after 3 incorrect entries - if you do and it's different from the s/n, post back with the code?

Hi,

 

If you have an Elitebook, contact HP Business Support - they should be able to send you a binary file you can use at boot to remove this password.
