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.

Forgot the password of bios of acer aspire 5584 wxmi model: zr1


Hi,
1. Go and download the bios file - ftp://ftp.work.acer-euro.com/notebook/asp.../bios/v1.06.zip
2. There should be a file call AG1A-106.EXE inside Alviso folder, just extract this file to the location you like.
3. In windows, use cmd (Command Prompt) to run this application.
4. The syntax should be ---- AG1A-106.EXE /ldcmos /reb -----
5. It may take 1 minute to load up, when it appears, just flash it.
6. Computer will restart after flashing and password should be cleared.
7. Don't forget to set back the BIOS settings if required.

Hope this helps!

Please rate my response!!

My acer aspire one crashed and i need help


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).

Forgotten hdd/bios password


The only way to reset the BIOS password is to find the jumper pins on the motherboard and set them to the clear state and remove the CMOS battery. It resets the CMOS to the default state.
Your best bet is to contact tech support and explain the situation to them

Bios Password Reset


The only idea I have is to find and disconnect the CMOS back-up battery after removing main battery and unplugging the AC adapter. That SHOULD clear the bios completely, wiping out the password, the date, and everything else.
I know this works on desktops, and most laptops, but no promises, and the cmos battery may not be easy to access.
You should probably leave the battery unhooked for at least 1-2 minutes to be sure it clears.

Hope this is some assistance!
