Let see, pretty much you will have to tear your computer apart, I mean disemble it by taking the bottom cover, all the screws around the edge on the bottom, take the battery out, and there might be few smaller screw that needs to be taken out, then the optical cd-drive needs to be taken out, then there are like 2 or 3 small screw there located where the cd-rom slot is to be screwed off. Then on the other side, pry the top half of the laptop where the power button is off, then unscrew the screw holding the keyboard out, take out the keyboard, and slowly disconnect all cables to the keyboard. I'm not sure where the Cmos battery is located anymore since it's been 2 years since I took this model laptop apart, but then I think there some sticky cover near the palm rest that need to be pull out, and if I remember the cmos battery is there, if not it somewhere around the motherboard, but what you want to look for is a silver round battery that looks about the size of a nickel out. You'll have to take it out for a few minutes and then put it back it. This will allow a hard clearing of the Cmos bios which will reset it to original default value. Just becarefully since there is alot of screw and cable to take out to just to get to the battery.

Hi

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
Good Luck

REST BIOS ACER EXTENSA 5620Z


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.

I have a bios password in my acer extensa 522u and i forgot it. how can i remove that password?


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.

Acer extensa 4220 bios password


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.

The computer locked and I can not unlock because it won't let me type inn my password. no letters appear when I type. Acer extensa 4620-4431


For security reasons, some laptops do not show passwords when you type them on the password page.
For your own case however, I would suggest that you should just try and reset the Laptop Password to its default settings by removing the CMOS battery. This means you might have to unscrew your laptop at the back, and try to locate the CMOS battery, remove it from a few seconds and replace it. This method will automatically reset your password to its factory settings.
If you cant unscrew your laptop by yourself, you can easily get a technician to do it for you.
Hope it helps you out.
Goodluck!
