HP Compaq nx7400: need bios password

Stuck on blue screen of password market

I've erased completely the laptop just bought from a friend and I did ' t know I needed.

Any help is appreciated, thanks.

CL; earing the password depends on if your friend set security all in the BIOS.  If it did not, so everything should be pretty simple. If he did, the systemboard will be replaced.

The following quote is from the maintenance & service guide for your laptop.

"1.2 resetting the computer if the computer you are performing maintenance has an unknown password, follow these steps to reset the password."

These steps also clear CMOS. ✎The following steps will not erase a unknown password if the rigorous security option has been enabled in the BIOS.

So stringent security are enabled, the system board needs to be replaced to reset an unknown password.

See section 5.21, "System Board" for more information on replacing the system board.

Before replacing the motherboard, follow these steps to ensure tight security has been properly activated.

Activation of rigorous security offers better protection for the turning on and password administrator password and other forms of authorization of power.

Rigorous security are enabled/disabled by accessing the password Options menu in the computer Setup utility.

See Section 2.1, "Start the computer installation" for more information.

1. prepare the computer for disassembly (see Section 5.3, "Prepare the computer for disassembly," for more information). Remove the battery from the time clock (RTC) real (see article 5.16, "RTC battery" for more information on removing and replacing the RTC battery).

2. wait about 5 minutes.

3 replace the RTC battery and go back to the computer.

4 connect the power supply to the computer. Replace any battery at this time.

5 turn on the computer. All passwords and all CMOS settings have been cleared. »

    Your model is on the list of the piloted.

    Contact HP and they should be able to send you a file custom SMC.bin that you can use to reset the password at startup.
