Acer Extensa 4620Z bios password reset

We have a Acer Extensa 4620Z  that is out of warranty and Acer requires proof of purchase for service (which of course the customer can't find after two years)---the customer's teenager set the password as a joke and can't remember it--pulling the battery for a week doesnt work--no jumpers to be seen---Acer tech support is zero help/sympathy.

the most likely answer is you will have to get it back to acer to have them provide you with the master password, apart from that resetting the bios will not work on most laptop due to security.

acer will only be able to generate the master password from the service tag on the machine.

although there are some software out there that lets you recover but sorry to say they are not reliable.

so the machine is kinda stuck at this point.

As punishment, let the teenager sit for 1 hour a day and try to remember the password, or pay for a new machine...


I hope this helps !

You can't remove the password, without knowing it !
modern laptops keep it in a security chip - for anti-theft reasons
resetting the bios does not help;  nor does removing the battery, since the password is not in there
you would need to know in what chip it is, and how to reset that
you have to turn it in to the manufacturer, and show proof of ownership - then they can help
or replace the mobo !

some services on the net claim to do it, but not free !
