I cannot remember the password I set for my Acer Aspire 1 D250 netbook computer. Will removing the CMOS battery reset the password?

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.

disconnect the CMOS battery or set the reset jumper to reset, with the primary laptop battery removed, and the ac adapter disconnected, hold the power button for 30 seconds to a minute, then re-assemble and reset jumper settings and power the laptop on, there is no OEM backdoor password for acer computers

Try removing the main battery and unplug the power, then hold the power on button down for 30 seconds, if this does not work, remove the cmos battery for 30 seconds to reset the bios

Hi, don't worry. windows password unlocker can help you.
Just download it from http://www.passwordunlocker.com/products/wpu.html

There are free methods as well, you can search for them in google. Manual changing of password requires an advance user.

You can also reset your netbook using recovery disk. Please see this: http://www.ehow.com/how_5833609_restore-acer-aspire-one-series.html

To reset your bios password please refer to either one:
!BIOS - is a PC BIOS toolkit offering password removal/decrypt and BIOS settings modification/backup/restore.

Please let me know if it was helpful.

Thanks

Can't remember Windows password? I have forgotten my login password for my Acer Win 7 laptop. I used Windows Password Recovery Tool to help me finally! It is really a useful tool!

the password could be administrator, that is what is used from factory most of the time

If you are looking for Drivers then I would recommend an Automatic Driver Download Tool that can detect all your installed hardware, search, download and install all the required latest model and manufacturer specific drivers automatically.

Regarding the Battery, some intelligent batteries remember the charge. If the first time you do not let it discharge completely, then it remembers that setting and never charges more than that. So just try discharging your batteries to zero percent and try recharging it. I am sure it will charge to 100% this time. Read more at www.fixpcfreeze.com

Hi the only possible way to reset the password in the BIOS is to reset the CMOS battery. It is located in one of the panel below the sys (you must have proper expertise to do this) towards the right hand side. The battery is set on a jumper You first need to disconnect all power source i.e adaptor and battery. than remove the panels to try and locate the CMOS Battery. Remember not to tuch anything else or connect any of the cables any where else it may cause a problem for the sys and you. Once the CMOS battery is reset the BIOS password will have gone.
All the best

If it's at bootup:

You need to temporarily remote the CMOS battery from the motherboard to reset the bootup password.

If it's at login:
