F you need to bypass the BIOS password - assuming that this is a desktop pc, you need to remove either the BIOS battery from the motherboard or switch the bios reset jumper to another position for a while and then back, I can help you more with that if you first clarify is this a bios password or not and then is the computer a laptop or a desktop pc.

I have a dell inspiron 6000 laptop. I found it. it won't go to boot menu, or setup. Somehow it has a password authentication password, how to I bypass that and do a complete system restore on it... PLEASE...


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. If you 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.

How to Bypass BIOS Passwords


BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS v 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. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

Acer aspire IE3450P BIOS Password


A BIOS password is a protection measure that can be used to stop someone powering up a computer system or making changes in some of the computers most sensitive areas. Many big name computer manufacturers such as Dell and HP lock the customers out of this area because they don’t want the customer changing anything and potentially damaging the machine (which the manufacturer may have to warranty). However, when someone like a computer technician or hardware enthusiast needs to make some hardware changes to the computer, they will need to access the BIOS. Here are some methods to bypass or remove a BIOS password.

NOTE: Do not try to guess the password on a pass worded Hard Drive. 3 wrong guesses will often result in the information on the hard drive being lost forever.
How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
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 a lot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.
remove-battery.thumbnail.jpgAnyway, 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.
remove-bios-battery.thumbnail.jpg 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 boot up now, you will need to go to “Load BIOS Defaults” in BIOS and save the changes to fix them.


Please rate me if this solution works for you

Thanks......Have a great time.

If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk. 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 manufacturer's 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. 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.

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

Need to bypass or hack the bios password for IBM X41 PC Desktop


okay guys i found i new way to reset the pass with only a screwdriver …

here is a picture from an IBM X41 tablet i reseted the pass today
http://ug1.kw.cx/ug/0257/1549/123784929_full,r,470×470.jpg
you have to put the screwdriver between the 2 pins to contact them .. and now power on ya machine and go to the bios … you will receive a message with an security chip error or something like that
this chip was on the bottom of the mainboard … i think the T Notebooks (T40 , 42 , 43 , R50, R51 have the chip under the touchpad
will share this here for ya guys
i trade with used computers so you have to try many thigs to delete passwords ^^
