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.

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.

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).
