The password that was created on the hard drive (especially if it came from an IBM, or HP/Compaq) cannot be removed by removing the BIOS battery. The password is stored on the firmware chip and there are no backdoor passwords.
The power on password and hard disk password are created from the BIOS setup and it is stored on an EEPROM chip on the laptop.
These password protection methods are designed to prevent unauthorized access to the laptop its data and the hard disk data. Removing the hard disk and inserting it into another computer will not work.

I was given a IBM think pad 2626.My friend can't remember the password. What can I do?


There are three passwords used at a typical customer site:
the Setup password, the HDD password, and the Power
On password.
Ÿ Power On password:
1. Power off the computer.
20 ThinkPad 390E 2. Remove the battery pack and AC Adapter.
3. Remove the backup battery (RTC) for 20
minutes or use a screwdriver to touch the
backup battery (RTC) for 1 second.
4. Put back the backup battery (RTC).
5. Power on the computer and wait until POST
ends.
6. Verify that the password prompt does not
appear.
Ÿ Supervisor and HDD passwords:
The Supervisor password and Hard Disk password
(Hard Disk1 and Hard Disk2) are security features
that are used to protect the system and the hard disk
drive data from unauthorized access. No overriding
capability is provided, so it cannot be replaced if they
are forgotten. If the customer forgets the Supervisor
password, the system board must be replaced. If the
customer forgets the Hard Disk password, the hard
disk drive must be replaced.

I have an aspire one acer computer and I forgot the password ... is there anyway to recover or change password without lossing anything??


Disconnecting and reconnecting the Complementary Metal Oxide Semiconductor (CMOS)/Real Time Clock (RTC) battery can work to clear Basic input output System (BIOS) passwords in some models. The CMOS/RTC battery on portable computers can sometimes be accessed by opening one of the small compartments underneath but, more often than not needs the computer to be disassembled. On many portable computers, removing and replacing the CMOS/RTC battery has no effect on the BIOS password because the BIOS memory is archived in BIOS-related capacitors which retain a charge even if the computer is disconnected from the mains electricity or has its battery removed.


If the forgotten password is an Operating System Password then you really only have 4 choices:


Try to recall the password;

Use another computer to download password recovery software, burn a password recovery tool stored on a flash drive or a CD (depending on what the BIOS will allow) and use that to find and enable you to clear or change the password to something more memorable (see below for websites);

Remove the hard disk drive (HDD) and use another computer to connect it to and back any important data up to the computer or another storage device, then reinstall the HDD to the original computer and reinstall a fresh copy of the Operating System (O/S), drivers and programs;

Or (if no important data was stored on the HDD), just go ahead and wipe everything on it by installing a fresh O/S, drivers and programs.

What's your problem?lockedout of my computer


It depends what type of computer it is and what type of password you are talking about. If it is a Basic Input Output System (BIOS) password and the computer is a desktop PC, then all you have to do is disconnect the power cable and other cables, open the computer and then remove the flat silver Complementary Metal Oxide Semiconductor (CMOS) or Real Time Clock (RTC) battery for a few minutes to clear the BIOS cache of its memory, then replace it, close the computer, reconnect the cables and then start the computer again.
If your computer is a laptop, notebook or netbook, the removing the CMOS/RTC battery can also work to clear BIOS passwords in some models. The CMOS/RTC battery on portable computers can sometimes be accessed by opening one of the small compartments underneath but, more often than not needs the computer to be disassembled. On many portable computers, removing and replacing the CMOS/RTC battery has no effect on the BIOS password because the BIOS memory is archived in BIOS-related capacitors which retain a charge even if the computer is disconnected from the mains electricity or has its battery removed.
If the password is an Operating System Password then you really only have 4 choices. Either try to remember the password, use another computer to download password recovery software, burn a password recovery tool stored on a flash drive or a CD (depending on what the BIOS will allow) and use that to find and enable you to clear or change the password to something more memorable; remove the hard disk drive (HDD) and use another computer to connect it to and back any important data up to the computer or another storage device, then reinstall the HDD to the original computer and reinstall a fresh copy of the Operating System, drivers and programs or (if no important data was stored on the HDD) to just go ahead and wipe everything on it by doing a fresh Operating System, drivers and programs installation.

Forgot password for Acer TravelMate 240


RTC battery inside somewhere to keep the password of your computer.

Try to find the RTC battery (acer almost used cr1220 ) and take it off from socket wait 10 seconds and put it back again .

You need to disassemble the unit ~take the keyboard and heatsink plate off ~you will see the RTC battery.

You may type cr1220 to search the picture of RTC battery on line easy.

Good luck.
