Reset bios password

Want to reset unknown cmos\bios password on Acer Extenza 4630z.

Have goggled for information and it is not very good information.

Google suggests:

Remove plate covering cmos battery under the keyboard, on the 4630z there is on plate.

Take apart the laptop and there will be a red reset button on the mother board, cannot get laptop to come apart.

I am:

Looking for pins to jump (have not seen any)

Looking for way to remove round battery under the rechargeable battery, It appears to be glued in


Any other suggestions for resetting this password.

    I have sent this request several times.

    Reason for the duplicate sending is because I was trying to get my account setup correctly.

    Answers that I have received thus far are the only option I have is to return these units

    to Acer. Not what I wanted to do but it seems like the only option.


    Will continue to look at site to see if any one has figure out how to do this.
