Try disconnecting the power to your computer, open up your computer case, locate and carefully remove the lithium battery. It should reset the BIOS to its default settings.

Let me know what happens!

How to remove BIOS password


If you have the current password, use it to access the bios password screen in your BIOS menu and leave the new password blank.
Assuming you don't have the BIOS password, there is generally a white jumper connecting two pins on the system board. With this removed, the BIOS password will not lock out changes to the BIOS. This is especially useful if you've purchased a used system that the previous owner locked out.

I just want to reset my power on password, nothing is broken and I didn't forget the password, just want to change it


To change a bios password: enter the current password and select the appropriate enter bios key. When in the bios, navigate through the menus to find the "set boot password" option. This will normally prompt you for the old password then allow you to enter a new password. To remove the password press enter without typing a password.



To change a windows password, log in. Select start > control panel > user accounts
At this point, select the user you would like to change and select change the log in password.

Forget bios password


hi ,
I had same problem, just remove plastic trim ( the one with the switches to power on etc etc ) and you will see a micro dipswitch. It should have all 4 switches to 0, move switch 1 to position 1 power laptop and password should be removed. Turn laptop off move switch 1 back to posiotion 0 and replace the plastic trim. It worked for me on an ACer Aspire 3610.

good look
