Clear bios password on acer aspire 5100-3959

I purchased an acer aspire 5100-3959 used and i can access the xp operating system but i cannot access the bios setting because the original owner has a password enabled. my only reason to have the bios password cleared is so i can perform a system restore and return the computer to original factory settings.
I cannot remove the cmos battery as it is sautered onto the mother board and will break if tampered with. can someone plz help me?

If you remove the base plastic cover to expose the memory ect.. All you have to do is locate the wifi card then remove it (very easy) you will then see the system board battery. Now place a flat screwdriver so that it touches both of the wires going to the system board from the battery. this should reset the bios.....

I think Acer Aspire 5xxx notebooks of this era use Phoenix NetBIOS Version 4 Release 6 BIOS.

There should really be no need to open up your laptop & remove the memory to short the jumpers or remove the cmos battery to reset the Supervisor Password. You run a much greater chance of damaging the notebook due to static electricity or incorrectly shorting the jumpers while the power is applied...

Instead the best method is to approach it from the software perspective and by writing down the "BIOS Hash Code."

When booting the notebook, press F2 to enter the BIOS and (in the case that you have forgotten your Supervisor Password) after entering the BIOS password incorrectly three times, you will be presented a "System Disabled" message with a checksum value example: [12345]. Write this down.

Now, thanks to a very talented programmer/hacker named Dogbert, use the pwgen tool to crack the Supervisor Password.

Also, as somebody already mentioned you can hit Alt+F10 to bring up the Acer eSettings so you can try the password within Windows, under the "Security" tab.

Use the pwgen tool (for Windows):

You can touch the two legs where the battery is attached to the motherboard and hold it for about 5 seconds and that should reset your bios password. I did it to a ace aspire one.

Hello, I own a repair shop and somebody brought me a ACER ASPIRE 5100 LAPTOP with a windows vista damage. So, I tried to reinstall but the problem was It has a bios password. In a limited way a could enter to a session of DOS and tried to reset the password running a couple of tools but neither works. There isn't jumpers to reset the bios neither desoldering the battery didn't work. So, I formatted the hard drive and that was a big error. I couldn't enter anymore.
The only thing that work was to install the hard drive how primary drive in a DESKTOP COMPUTER (the hard drive is a sata hard drive, but if you have a similar problem with other laptops with IDE interfase , you can buy a kit to install any kind of hard drive to a DESKTOP COMPUTER, the cost of the kit is like $20)
anyway, I installed the laptop hard drive how primary hard drive (I strongly suggest disconnect others hard drives of the pc) and install a copy of XP, then I installed again the hard drive in the laptop and I went to the acer page support and download the last version of the BIOS, and surprise !!! the password was gone and could put the cd/dvd like first device and reinstall vista without any problem . If you tried to leave XP, you will have a lot of problem, better do what I am saying, download the last BIOS and the laptop won't ask for a password. This solution help me to earn $75 to fix the costumer's laptop . Hope it helps you.

@Thriste... There are no jumpers on the Aspire 5100 notebook like you are discribing. You are thinking about a DESKTOP PC and that is of no help here.

I am having the SAME problem with my aspire 5100. I had a password for the BIOS, which I used right before I tried a system restore (ALT-F10), and it worked fine. After the restore (which keeps failing at 53% for some reason I have yet to find out about) my password does not work anymore. Acer will not tell me what the default password is either THANKS DIPSSHITX... Now I am stuck in Baghdad with no PC to use to talk with my family for the holidays and they refuse to help me. I had to wait almost 2 hours just to use a public PC that 50 other people are waiting on over here... Good times..Good times..

I recently was able to clear my bios password on my acer aspire 5100 by going to the acer website, and looking up my model number under support and downloads, once i found the downloads for my system, i download and installed the Bios Update which not only update my bios, it gave me the option to clear all passwords and stored data in the bios. Hope this works for anyone else with the same problem.

Setting up a password on the Acer Aspire prevents others from accessing the computer without permission.

If the user is unable to supply the correct password at startup, the computer will lock the hardware and fail to boot.

This security measure is a useful feature, but it can create serious problems if you forget the password.
Basics

The Acer Aspire stores the password in a component called the complementary metal-oxide semiconductor.

This component is integrated into a random access memory chip embedded on the motherboard. The CMOS holds data that the basic input/output systema critical software utility that controls how the computer operates at startupaccesses when the computer boots.

If the BIOS detects that a password is registered in the CMOS, it will prevent the computer from booting until the user enters the password correctly.

Depending on which model of Acer Aspire you own, you may be able to clear the CMOS manually.

Contact Acer before attempting to clear the CMOS, as opening the computer without permission could void your warranty.

Desktop Models

Some Acer Aspire desktop models come with a jumper that is used to clear the password and other settings stored on the CMOS.

This jumper is located on the motherboard and is often found next to a label such as "JBIOS1" or "CLR_CMOS." To clear the CMOS using the jumpers, turn off the computer, disconnect the power cable and remove the case cover.

Remove the jumper shunt from pin 1 and pin 2; then place the shunt on pin 2 and pin 3. Return the shunt to its initial position after 10 to 15 seconds.

If the Aspire doesn't come with a jumper to reset the CMOS, the CMOS can be reset by removing the lithium coin-cell battery instead.

Removal is accomplished by pushing down on the tab securing the battery to the motherboard and lifting the battery out of its slot.

Leave the battery out for 24 hours, and then return it to its original position with the positive sign facing up.

Laptop Models

Resetting the CMOS password on an Acer Aspire laptop is much more difficult than resetting the password on a desktop.

Disassembly steps vary from model to model, but on most models, you'll have to take apart the computer to access the CMOS battery.

Don't take apart the notebook if you don't have experience disassembling PCs.

After turning off the computer and disconnecting the AC adapter, take out the battery (different from the CMOS battery).

All visible screws must then be removed from the bottom of the notebook.

Remove all components stored to their separate compartments on the base of the notebook.
Turn over and open the PC.

Lift up the switch cover and remove the screws securing the keyboard to the PC, if any are visible.
Remove the keyboard.

Remove the screws securing the monitor to the hinges, and then set the monitor aside. Disconnect all visible cables connected to the motherboard; and then remove the screws from the top cover.

Remove the top cover to reveal the motherboard.
Locate and then remove the CMOS battery.

Leave it out of the notebook for 24 hours; then reinstall it and reassemble the Acer Aspire.

Other Options

If removing the CMOS battery fails to clear the password, or if you don't feel comfortable with the idea of opening your computer, you might be able to gain access to the computer using a backdoor password.

These special passwords were implemented to allow technicians to access locked computers. Not all models recognize backdoor passwords.

Most Acer Aspires use the Phoenix BIOS, and backdoor passwords for this BIOS include "BIOS," "CMOS," "phoenix" and "PHOENIX."

All of these passwords are case-sensitive.

RESET HARD DISK DRIVE LOCK FOR ACER ASPIRE


Step 1:
Which model of acer laptop ? there are many

The BIOS (Basic Input Output System) is designed to check the integrity of the computer hardware and launch the operating system. The BIOS also has basic security features that prevent unauthorized access to the computer by locking the hard drive with a password. The password is required in order to launch the operating system. That option can be disable without an changes to the operating system.

Turn your computer on. Press "Esc," "Del," "F2" or "F8" to access the BIOS. Use the arrow keys to go to the "Security" tab. Press "Enter." Highlight "HDD Lock," Boot Password" or "Hard Drive password" using the arrow keys. Press "+" until "Disable" appears. Go to the "Exit" tab, highlight "Save and Exit" and press "Enter." Press "Y" when prompted to reboot your computer without the hard drive password.

Forget password acer aspire 3610


Acer laptops are equipped with a BIOS utility. The BIOS (which stands for "Basic Input Output System") acts as an interface between the hardware and software installed on the computer. On some computers, a BIOS password may be required in order to boot the computer and make changes to the BIOS settings. If you are unable to access the BIOS settings and do not know how to reset the BIOS password, you might be tempted to send the computer back to the manufacturer for repair. Fortunately, that's not necessary as there is a simple way to do this on your own.

Go to "Start," then perform a search for "Command Prompt." The Windows Start button is located in the lower-left corner of your computer screen. Double-click on "Command Prompt" to open the application. You will need to use MS-DOS commands to reset the BIOS password. Type the following commands one by one in the order shown: debug o 70 2E o 71 FF quit Make sure that you are typing the letter "o" and not a zero at the beginning of the second and third commands. Reboot your computer by clicking "Start," "Shutdown," and then "Restart." The BIOS password will now be reset to default. or To get into your computer's Basic Input-Output System (BIOS), your computer must be on, but your operating system cannot be running. If the Microsoft Windows operating system has even started to load, you will not be able to access your BIOS. This is why getting into the BIOS on an Acer Aspire netbook computer must be done specifically during your computer's initial boot-up sequence, which happens immediately after pressing the power button on the device.


Turn on your Acer Aspire. Press and hold the "Ctrl" key. Press and hold the "Alt" key. Press and hold the "Esc" key. This key combination will open the BIOS on your Acer Aspire.

Below are the steps for the resetting of the password. Below the steps is the link for the service manual. On page 113 is the picture of the jumper pads that need to be "shorted" to reset the cmos.

Steps for Clearing BIOS Password Check
If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:

• Power Off a system, and remove HDD, AC and Battery from the machine.

• Open the back cover of the machine, and find out the HW Gap on M/B as picture.

• Use an electric conductivity tool to short the two points of the HW Gap.

• Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.

• Restart system. Press F2 key to enter BIOS Setup menu.

• If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.

NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).
