I forgot my HP Probook 4230s Bios Password

HP Probook 4230s
Microsoft Windows 7 (32-bit)

I forgot my hp probook 4230s bios password. I tried the combination keys for reseting the bios but i don't know exactly how to do this process. I also tried some software methods like cmospwd and some other methods but failed.I also tried removing the batteries both main and the time battery for about an hour but nothing is working. Please help if there is any solution. Thanks.

Contact HP and they should be able to send you a customized SMC.bin file which you can use at boot to reset the password.

When talking to the HP rep ask them to escalate your service request.

 

Or download these files.

Insert clean USB flash drive.

 

Then run USB Image tool.

 

Choose the flash drive then click on RESTORE.

 

After restore remove flash drive.

 

Insert flash drive into locked laptop and boot. ”If HDD is installed remove before booting.”

 

At C:\OUTPUT   type CD.. “Then hit enter”

 

Type HPBR   “Then hit enter”

 

First thing is to save your settings.

 

Select #3 re-program.

 

Press “S” to save system information.

 

Type HPBR and hit enter.

 

Since your model is not listed select “SHOTGUN.”

 

After reboot repeat “SHOTGUN” a second time.

 

Let me know the result so I can update my list.

 

Some instructions here. “If you cannot boot from USB there are instructions to make a bootable HDD.”
