As another option you could try resetting the jumper. Some boards save the password regardless unless the reset the BIOS by using the resetting jumper. Refer to the motherboard's manual for further information on how to do this.

When you say you cleared the bios password, did you actually remove the cmos battery for about 15 minutes or did you just delete the old password, as acer normally protect the password and sections of the bios, removing the battery or shorting it is normally the only way.

    this would work if there was a cmos battery or jumper but on this model of laptop they are nowhere to be found. Please direct us if you know the location of where they might be. Thank you

SOURCE: asking for bios password I have no password


Unfortunely someone has put a boot password on the system. The only way to get rid of the password is to remove the CMOS Battery backup. This battery can be found inside the unit so opening it up is the only to get to it. It is a nickel sized battery. Turn on the unit while this battery is out of the unit, wait unitl u get wrong time message. then turn off the unit reinstall the battery and all passwords will be gone.

SOURCE: hi, I updated the BIOS

It sounds like the BIOS may have failed, which is very difficult to fix unfortuately. If a corrupted BIOS will not allow you to boot at all, you will either have to have the BIOS chip removed and flashed manually, or replaced with a new BIOS chip.

There are other possibilities however.

Do you hear any system beeps at startup? If so, that generally indicates your BIOS is still functional, and one or more BIOS settings may have been corrupted. If this is the case try hooking the laptop up to an external monitor. If your BIOS flash changed the screen output settings it might be preventing it from displaying on the laptop LCD.

As far as getting your assignment, you can put the harf frive into a destop computer and retrieve your files that way for the time being.

To remove the hard drive:
***Unplug the Laptop and Remove the Battery*** It may appear to be off, but it's better to be safe than sorry. On the bottom of your laptop there is a panel in the shape of an 'L', which should have 5 screws. Unscrew all 5 screws and remove the panel. You will see your harddrive in a metal cage. Remove the necessary screws and remove the harddrive by sliding it out of it's connector, then lifting it out. You should now be able to plug your HD into any computer with SATA hookups (make the connections with the power off). Now you should be able to power up the computer and access your files.

Hope this is helpful!

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).


I forgot the security password

here are 2 password type first 1 is bios password if tell me about your bios password it prompt when u powerup follow procedure below

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

And if u tell about windows password
Then when you power up the computer press F8 key then enter in safe mode then wait until it prompt for user password

then enter in administrator then if u able to enter then reset your password.
But if u set and forgot default administrator password then u should need winxp recovery disk.


Computer Log In lost

If this is a Windows password, enter safe mode at start up by pressing F8, log in as administrator, from here you can clear any user passwords. Now, if this is a bios password you will need to contact Acer support.


If this is an operating system password, enter safe mode at start up by pressing F8, log in as administrator, from here you can clear user passwords. If it's a bios password, then you will need to contact Acer support.


forgot my bios password,
pleas help me
my notebook is acer aspire 1350

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!
