Hi,

Elitebook system is locked due to incorrect BIOS password.

Can someone please suggest any solution.

Thank you!

Hi,

At the password screen, hit enter 3 times. 

If you receive an 8 digit 'halt code', post back with this code.

If you don't receive a halt code, you will need to 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.

You can contact HP Business Support in your country via

or

Just to note, if you do need to go the HP route, don't try removing the rtc battery.  It won't remove the password, but it will reset the clock - as smc files are time coded, a large disparity between the system clock and the time encoded in the smc will cause it to fail.

Hi,

It isn't showing any error code, just says - system locked, press power button to reboot.

And regarding CMOS battery, unfortunately i have already removed it & tried to reset out of this knowledge.

Thank You!

Hi,

You're welcome

The best thing would be to explain the rtc removal to HP Business Support when you contact them for the smc.
