This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Just a heads up that this has a possibility of not working since it is normally the procedure of desktops.

If you are confident with opening the laptop on the bottom there should be compartments. As you go opening them one of them should have what looks like a black covered CR2032 Flat Cell Battery.

You will need to remove the laptops battery and unplug the AC Adapter. After this let it sit out for 2 minutes. Once the time is up put the clock battery back in, then the battery and finally the ac adapter once you have put the laptop compartments back together.

Note: This works because the Black Covered CR2032 battery lookalike's purpose is to keep power to maintain the system settings. Once it loses power the chips no longer retain the information causing the BIOS to go back to default settings.

Also Note: This may not work if the BIOS has another method of keeping the settings stored.

Hi Michael,

ready for a challenge?

This homepage hold a load of Backdoor passwords, - one of them will bypass you forgotten BIOS password. If you don’t know your type, you´ll have to try them all out, or until you hit the right one:
http://www.computerhope.com/issues/ch000451.htm




If the above doesn’t work, try this:
!BIOS, download from here:
http://www.technibble.com/downloads/misc/BIOS320.EXE

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
CmosPwd will recover the BIOS password for the following BIOS versions:


ACER/IBM BIOS
AMI BIOS
AMI WinBIOS 2.5
Award 4.5x/4.6x/6.0
Compaq (1992)
Compaq (New version)
IBM (PS/2, Activa, Thinkpad)
Packard Bell
Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
Phoenix 4 release 6 (User)
Gateway Solo - Phoenix 4.0 release 6
Toshiba
Zenith AMI
Download !BIOS and save it to your desktop. Then, open a DOS command windows by going to
Start -> Run and type: cmd
Once you see a black screen in front of you, type: cd desktop
You should now see something like: C:Documents and SettingsYourUserNameDesktop>
Now type the name of the file you just downloaded, if you haven’t changed the name just type in: bios320.exe

Use the down arrow and choose “Crackers” and then press the right arrow. Using the up and down arrows, select the BIOS that the motherboard is using and press Enter.
You should now see a menu asking what you want to crack, in most cases its the Supervisor or System Passwords you want to crack, so press the 1 key on your keyboard. It will then show you another menu asking how you want it to be cracked. Option 1 is pretty good so try that first by pressing the 1 key on your keyboard. You should now have your BIOS password.
Reboot the computer, enter the BIOS and try it out.

NOTE: Because of this applications password cracking abilities, some anti-virus software may report it as a virus/trojan. This is a false positive.

If the above doesn’t work, try this crack link:
BIOS password crack, download from here:

SOURCE: Boot sequence / bios password issues with Acer Aspire 5100

for removing bios password you must have to remove cimos bettery for few mnuts but for doing this you have to open case of laptop
and it is not adviceable because your notebook is new one
so find any service station if yor laptop is in warranty period or you may lose your warranty
there isn't any other way to clear cmos without opening case of your laptop and remove cmos bettery
unless you will get cmos password but as u said you didn't put password in your laptop it might be possible that your notebook manufacture him self had put any password in cmose as a company policy
in that case also you must have to go to them

The finger print bull is how that password came up for me and they want a 125.00 to remove it. I called the better business bureau and filed a complaint. They shouldn't have any right to control your laptop. I to have a 6292 , took it apart as far as I could and could not find jumper or password. This is a gimmick to make money.

SOURCE: reset bios password or remove

The laptop password cannot be reset by removing the battery and there is no jumper for the CMOS or bios reset. You must go to Acer to obtain the master password as laptop computers have NVRAM (non-volatile RAM) that retains the password forever as an anti-theft protection. Steve Medley
