Guide to remove BIOS password of Acer computer (Both Laptop & Desktop).
There are four ways to remove the BIOS password
1. Reset Password BIOS via Backdoor BIOS Password.
2. Reset Password BIOS via Software.
3. Reset Password BIOS via hardware.
4. Reset Password BIOS via default manufacturers.
You can contact acer support or search internet for Acer's default BIOS password and that would be real easy for you, But if you are comfortable enough to use Dos you can also try this method.
OK, here is my guide to Remove Acer Bios password computer via
Software. This has been done on testing machine Laptop Acer Aspire
3620/ Travel Mate 2420. Anyway, I'm not sure it will work on every Acer
PC/Laptop so just consider to do at your own risk, I’m not responsible
for any damages caused by this guide.
As we know most of Acer computer (Laptop & Desktop) allow us to
setup BIOS in Microsoft Windows (9x/XP/Vista) environment. Great, this
is the powerful that help us to remove the BIOS password because all we
know if we enter Setup Utility at the boot time we have only three
times of filling the password and if all wrong then the system will
The program helps us to enter Acer BIOS setup in Microsoft Windows is
“Acer eSettings Management” which comes with the CD when we buy Acer
PC/Laptop. If you lost the CD then just come to Acer website to
download the program.
Before you can install “Acer eSettings Management” you have to install
program called: “Acer Empowering Technology” so you’d better to
download both of them from Acer website and install & restart your
computer to be ready for the job. Here is the link of Acer website,
just come there and sellect right series/model of your computer to
download these programs:
Another one program is also very important we will need called:
“CmosPwd” - CmosPwd is a cmos/bios password recovery tool. CmosPwd is
under GNU Public License. You can freely distribute it. It can be
compiled under Dos, Windows, Linux, FreeBSD and NetBSD.
Download it here:
Guide to install CmosPwd and remove password:
1. Download & extract to a folder. I put it in drive D like this: d:\ cmos
2. To work on cmos memory, ioperm need to be installed and running.
ioperm gives direct port I/O access for specified ports to user-mode
process (ring 3) using Ke386SetIoAccessMap and Ke386IoSetAccessProcess
Log on to Windows as Administrator priviledges and do as follow: (see picture):
a. Click Start-->Run: type CMD hit Enter on your keyboard.
b. now us the CD command of Dos to come to d:\cmos\windows. (here is: d: hit enter; cd cmos hit enter; cd windows hit enter).
c. when you are already in d:\cmos\windows in drive D then: type “ioperm.exe –i” hit enter.
d. to start ioperm service: type “net start ioperm” hit enter.
e. ok, type: “Cmospwd_win.exe /k” hit enter, we will see:
1 - Kill cmos
2 - Kill cmos (try to keep date and time)
0 - Abort
Type 1 and hit Enter to clear cmos.
f. run the Acer eSettings Management program: start-->program-->Acer Empower Technology-->Acer eSettings Management.
g. now come to the: Bios Password to see: if you still see password
enable, that means we fail but if we see they are Disable so we are
done. Remember if we success remove password then we have to create a
password for it and then remove it and click Apply to save to cmos
memory. This is very important because sometimes we see it Disable but
when reboot the computer they are Enable again cuz the password is
still in the CMOS.
That’s all, good luck & don’t forget to set an easy password later.
