I forgot my bios password, i want to reset my bios password


A. By Removing the CMOS Battery:

cmos_battery.jpg Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.
B. By Using the Motherboard Jumper:
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

Tip

Reset BIOS Password


You set a BIOS password on your computer. The next time you start up the computer, you forgot what it was. How do you reset it?

1. Open up the computer to expose the motherboard. For normal desktop computers
,you will have to slide the case cover or side door off. For Laptops,remove the keyboard by unscrewing the screws securing it to the unit.
2. Look for a battery on the main board. It will either look like a large watch battery or like half of a AA.
bios-battery.png3. Remove the battery for about 10 seconds.
4. Place the battery back on the motherboard.
Ifthis doesn’t work, it is likely that you will need to look in thedocumentation for your motherboard to learn the jumper that will resetthe BIOS password.

How can i reset my bios password ,logged out/dell computer


You can call Dell and they can reset the bios password for you. But if it doesn't have a warranty anymore you can simple open the casing of your computer and there's pin(jumper) on the motherboard that you can pull out and then put it back in. The password will be reset.

Backdoor Passwords READ COMPLETELY!!

Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations.

WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords.

Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.

Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.
Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.

Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all. IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system.

How do I reset my password on m panasonic toughbook cf29


The boot-up passwords are normally set by the computer's BIOS. So a reset of the BIOS is normally performed in these cases. It requires opening your laptop's case, and removing not only the Big battery, but the tiny dime-sized battery on the motherboard. It's used to maintain BIOS settings and the Date/Time. Removing this battery will cause the custom settings to be wiped, and putting the battery back in will cause the default factory settings to be restored.

If you're talking about your windows password, it requires using software to crack your copy of windows. Which violates this site's rules.

Don't reset password BIOS HP DC7100


If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard.

Open the CPU casing locate the CMOS battery in motherboard and remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper.

This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.

If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it. Good luck!

I have a dell 4600 that I got from my daughter . which I had to re-install and It has a password in the bios for the set up and my daughter dont know




Hi katmbutts;


Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:
    • Using a manufacturers backdoor password to access the BIOS
    • Use password cracking software
    • Reset the CMOS using the jumpers or solder beads.
    • Removing the CMOS battery for at least 10 minutes
    • Overloading the keyboard buffer
    • Using a professional service
Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive.

Backdoor passwords
Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops. WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times.

Overloading the KeyBoard Buffer On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key over 100 times in rapid succession. Jumping the Solder Beads on the CMOS It is also possible to reset the CMOS by connecting or "jumping" specific solder beads on the chipset. There are too many chipsets to do a breakdown of which points to jump on individual chipsets, and the location of these solder beads can vary by manufacturer, so please check your computer and motherboard documentation for details. This technique is not recommended for the inexperienced and should be only be used as a "last ditch" effort. I hope this helps, Don't forget to leave a rating. Mark

Bios default password


The BIOS default password is just blank, and it is not asked.

When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.

To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.

Password


that is because the password in question that you are trying to get past is the BIOS password most likely. Verify that your computer is turned off, remove power cord from back of computer, and find the jumper near the Bios chip on the motherboard. It will usually be close to the battery ( another option, temporarily remove the battery for about 30 seconds, then replace the battery into its proper position ). Be careful when you do this as some battery sockets are a pain to work with. Anyway in nearly all cases, the Bios reset jumper is located very close to both the battery and the bios chip ( firmware ). Removing the Bios reset jumper and positioning it one pin over from the initial position will usually reset the bios and get rid of the bios password requirement. Always put the bios reset jumper back into its initial position before re-appying power to the motherboard. Be careful not to leave anything loose lying around on the motherboard or in the case, else you might fry the motherboard..
Once you have successfully managed to get past the Bios password, then you should see the computer start to boot up normally and prior to Windows boot up and in the Bios routine you can configure the computer to boot to CD first. In many more modern situations, the motherboard is already configured that way.

PASSWORD PROBLEMS


Hi, To access or enter motherboard BIOS settings, on powerup either F2 or Del. If you just want to remove the password in your Dell Optiplex > The BIOS password may be cleared by removing the password jumper (PSWD) on the motherboard. This will also clear all CMOS settings: Open your casing, on your motherboard. find the CMOS password reset jumper (3-pin) on the motherboard; Remove the jumper from pins 1 and 2 and put it on pins 2 and 3 for about 5 seconds. Replace back the jumper on pins 1 and 2. Hope this be of help/idea. Good luck and kind regards.
