Hi,
Welcome to FixYa!

Are you the one who set up the BIOS password? If not, unfortunately, there's no way for us to retrieved the password. The only way you can reset the password to default settings is to reseat the CMOS battery on the motherboard, its a circular thing that looks like a battery of a watch,sometimes a pin hold it, just detached it then wait for at least 30 minutes then connect it back again,

Note: Before you reseat the CMOS battery,make sure that everything is unplugged on the computer, like AC adapter,battery and all external devices...

Hope this will help...Thank you for using Fixya...

    This doesn't work because the bios password isn't in the CMOS, it's on another chip in the laptop, so pulling the battery does nothing other than reset all your bios settings except the password.

    Luckily there's a tool out there to clear, reset or change your bios password on quite a few HP laptop models, more info here:http://h20000.www2.hp.com/bizsupport/Tec...

My laptop HP ProBook 4510s prompt computer open password befor going to BIOS or OS. And i don't know what is the password? So how can i reset the password to boot the computer.


When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there

also

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps you

Hi, Is it possible to reset/recovery admin Bios password on Probook 4310s ? And how, if Yes. regargs, Bob


To reset the BIOS password read the information from this link.

In case of your HP ProBook laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper and I wouldn't recommend doing it especially if it's under warranty.
