Bios reset HP Probook 6470b

[huhl01]

Dear people,

Last year I bought a secondhand Probook 6470b laptop with windows 8.1. I now like to change my windows system to win 10 but I can't because I dont know the bios password. I can't change the bios boot to dvd or usb.

Can you help me to free the bios?

Kind regards,

Jan Huhl

Hi,

For that Model, 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, 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,

Try using the online options starting on the link below.

Choose 'Continue as guest', enter your serial number and confirm your location - then click the 'Show options' button.

Thanks for the answer. There is no sticker with a serial on it. So on that site it ends there with no serial.

What to do with that? Is there any way to find it?

Hi,

Try tapping f1 as soon as you start the notebook.

Thanks for the help.
