Daughter changed password And can't access computer this screen keeps coming up every time I power up


She did more than change your master password, it looks like she erased most of you OS (Operating System) It would be worth taking it down to a reputable computer repair place and having them have a go at it. The might be able to save your files to put back on it once they reinstall an operational OS. Good luck.

Forgot my password


In computing, BIOS (basic input output settings) refers to the information stored regarding a computer's hardware configuration, the system date and time and any applied password. This information is known as the BIOS or CMOS settings--the BIOS is stored on a small battery-powered semiconductor chip known as the CMOS (complementary metal oxide semiconductor). Having a CMOS or BIOS password restricts unauthorized changes to the system's hardware configuration and, in some computers, may even be required for booting. A lost password may be reset by removing the CMOS battery, clearing the motherboard jumper or using a software-based password cracker.

1.Shut down the laptop and unplug its power cord from the wall outlet. Remove the battery cover under the laptop and gently raise the battery from its dock. Unplug any peripheral devices with a live power source connected to the laptop, such as a modem or printer.
2.Locate and remove the CMOS battery. Refer to your user manual or visit the manufacturer's website for your laptop's architecture. Follow manufacturer recommended procedure to access and remove the CMOS battery. Depending on make and model, this procedure may be more involved for some laptops and not others. The CMOS battery is a flat circular shape and resembles a watch battery.
3.Wait 30 minutes and then put the battery back in. This will erase all information stored in BIOS. Assemble the laptop, making sure you leave no loose connections. Power up the laptop and press "F1" when you get the "CMOS cheksum error" message. Type in a new password.

Clearing CMOS Jumper

1.Turn off the laptop and access the motherboard following recommended procedures.
2.Locate the jumper in the motherboard. If you do not have your motherboard documentation, locate a single jumper near the CMOS battery. In some laptops, the jumper may also be labeled in the motherboard. Put the jumper setting to "Clear" and reassemble the laptop.
3.Turn on the computer and hit "F1" when the "CMOS checksum error" message is displayed. Navigate through the BIOS settings interface to load default settings and apply a new password.

Using Password Remover

1.Download a software-based BIOS password cracker. There are numerous free programs able to recover or delete CMOS or BIOS passwords from virtually all motherboard brands. Download the file from a trusted source and save it to the desktop.
2.Burn the installed file to a CD using image burner software. Insert the CD and access the password remover tool.
3.Note the password or use the program to set a new password.

I hope you find it very helpful. Thank you.

After replacing my hard drive my laptop hp compaq 6720 is asking for a power on password Ive never put one in


Using Computer Setup to Reset CMOS

To reset CMOS through Computer Setup, you must first access the
Computer Setup Utilities menu.

When the Computer Setup message appears in the lower-right corner
of the screen, press the F10 key. Press Enter to bypass the title
screen, if necessary.

-- If you do not press the F10 key while the message is displayed, you
must turn the computer off, then on again, to access the utility.

A choice of five headings appears in the Computer Setup Utilities
menu: File, Storage, Security, Power, and Advanced.

To reset CMOS to the factory default settings first set time and date,
then use the arrow keys or the Tab key to select File > Set Defaults
and Exit. This resets the soft settings that include boot sequence
order and other factory settings. It will not, however, force hardware
rediscovery.

See the Desktop Management Guide on the Documentation CD for
further instructions on reestablishing passwords. For instructions on
Computer Setup, see the Computer Setup (F10) Utility Guide on the
Documentation CD.

For more details and pictures see the help pdf:

I forgot the bios password, unable to gain access to the windows professional xp and can not use computer


Hi,

The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

Anyway, open up the computer case using a screw driver and locate the flat, circular and metallic CMOS battery. It should look something like the picture to the right. Some computers have this part standing upright.

Once you have located it, observe how the latches are holding it. There are many different ways to remove a CMOS battery but the most common way on newer computers can be seen in the picture below.

Make sure to power down the computer, unplug the power cables and unplug any USB devices if they are powered. The computer must not be able to get power from anywhere for this to work. Take out the CMOS battery and wait 10 – 25 minutes before putting it back in. The reason for this wait is because the computer can still store power in its capacitors even though everything is unplugged. The waiting period allows enough time for them to discharge.

Plug everything back in, power up the computer and enter the BIOS again. If everything went well there should be no more password. In some cases, if you get weird error messages during bootup now, you will need to goto “Load BIOS Defaults” in BIOS and save the changes to fix them.


Good luck!
And Thanks.

Dont have password


There are two sections (that come to mind) when a password is requested in starting a computer. BIOS or Windows Passwords.
WINDOWS PASSWORD This will be after the windows logo as come up. Depending on which version of windows you have, you will need to find a windows password reset tool. 
A lot of these will require you to boot from a CD that you have created from an ISO image. If this is is confusing, head into a computer shop and ask them to do it.  Alternatively, reformatting the machine by reinstalling windows over the top should eliminate the problem (and all of the data that is still on the machine.)
BIOS PASSWORD This will usually be during the 'black screen' phase of booting.
An IBM ThinkPad laptop can have three BIOS hardware passwords set
  • Power-On Password
  • Hard Disk Password
  • Supervisor Password

Power-On Password
RT/CMOS RAM has 8 bytes reserved for the power-on password and the check character. The 8 bytes are initialized to hex 00. The microprocessor can access these bytes only during POST. After POST is completed, if a power-on password is installed, the password bytes are locked and cannot be accessed by any program. During power-on password installation, the password (1 to 7 characters) is stored in the security space. Installing the password is a function of the built-in system program Easy-Setup. The power-on password does not appear on the screen when it is installed, changed, or removed. After the power-on password has been installed, it can be changed or removed only during POST.
Hard Disk Password
The hard-disk password (HDP) protects the data on your removable hard disk drive from being accessed by unauthorized persons.
Supervisor Password
The supervisor password protects the system information in Easy-Setup from being changed by unauthorized persons.
How to Reset an IBM ThinkPad Power On Password using Software If you can boot the IBM ThinkPad, KeyMaker will recover the BIOS password.
How to Reset an IBM ThinkPad Power On Password Using Hardware If you cannot boot the ThinkPad, you will have to reset the IBM ThinkPad password via hardware. If only the power-on password is set, do the following to remove the power-on password. Power off the computer Remove the DIMM (Memory) cover on the bottom side of the computer. Short-circuit the two password pads or put a jumper on the contacts to short the circuit. Under the short-circuit condition, power on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The power-on password is removed. Reinstall the DIMM cover.
If both the power-on password and the supervisor password are set, do the following to remove the passwords: Power on the computer by pressing and holding F1. Enter the supervisor password. The Easy-Setup menu appears. Click on the Password icon. Click on the Power on icon. Enter the supervisor password and press the Space bar. Press Enter twice. Click on Exit; then click on Restart.

Can't unlock my ibm thinkpad t23


Your computer has been protected by a Power On password.
If you didn't set this password then ask the person who set the password on the computer.
This password is near impossible to crack, try various names, pets, kid's names, family names/places, street names etc. There are no back door passwords and the password is not stored in the BIOS and removing the BIOS battery won't erase the password.
The password is stored on an EEPROM chip and you need electronic knowledge to build an EEPROM reader, then pull your laptop apart, solder the reader to your laptop, connect the reader's connector to a working computer, and run a program to read the contents of the EEPROM, identify the password from the downloaded data, unsolder the reader, put the laptop back together, boot up and insert the password. You can now enter the BIOS and change the password or remove it.
For further info goto http://sodoityourself.com

The Power On password and the Hard drive password are designed to prevent unauthorized access to the laptop and the data that is stored on its hard drive.
Removing the hard drive from the protected laptop and inserting it into another laptop will not work, you still cannot access the data on the hard drive without the correct password.
