To break BIOS password, you need to unpack the laptop
there is inner cmos-battery that should be removed for a while, and put it back to it's plase,
but this operation isn't easy to be done, it should go through technician.

Please tell us your results

You have to pull the cmos battery from the board. It is the only way to reset the password. Some manufactures back a backdoor password they do not share with the public though. Only real way to is to pull that battery.

how do I unlock the bios password acer extensa 4620

Hi

Just remove all the screws at the back of your laptop and remove the CMOS battery located in the motherboard to reset the BIOS setting.

Hi,

If you have forgot BIOS password then you have to reset CMOS jumper setting. Please follow the below steps: Open the Laptop back panel. Locate the CMOS battery, remove it & then with the help of a screw driver keep on pressing the terminal inside it and turn ON the computer for 10 secs and Turn Off (make sure you keep on pressing the terminal with a screwdriver while turning ON). It will short the BIOS setting. Now, fix the CMOS battery & restart the computer. This will take care of the issue.

Thanks and regards,
Jitha

To reset the BIOS read the information from this link.

In case of your Acer Extensa 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.

There's no way that we can determine the BIOS password of your laptop. But if you can disassemble your laptop and locate the CMOS battery you can remove the CMOS battery to reset the BIOS together with the password. After resetting the CMOS battery you will no longer be asked to enter a password for the BIOS when you turn on your computer. However, there are instances that even though you reset the CMOS it's still asking for the password, for this concern, the computer manufacturer should deal with this concern.
