It really depends on the Driver model.

On the latest models capicitors of BIOS can hold the charge for longer and you can easily change the battery with the new one.

If you have the old board just go ahead and change the battery as usual and dont worry for the settings at all.

You can load the safest default settings by pressings F1,F9,F10

Password for bios


It depends where the machine came from. It may have been put on by the shop that sold it, or a previous owner.

Sadly, I cannot find an online manual for this motherboard (it should be a MCP61PM-GM motherboard), which would lead to how to reset the BIOS. Have a look around the motherboad closely, and see if you can find a switch, or even remove the power and the battery for at least 24 hours.

This is some info I found that may help you:
"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."

In CMOS setip utility, I am not able to load fail safe or optimized defaults or set supivisor password.


Try opening up your computer and removing the CMOS battery. Should be the only battery on your motherboard (the thing everything plugs into) this will usually reset your bios. Some bios also have a jumper that needs to be switched but without knowing your motherboard model I can't be sure.

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.

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.

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.

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 …
will try to make a site with a tutorial to reset the tmp chip .. i think it works on every ibm notebook
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 ^^

Resetting a bios password


YOU NEED NOT TO USE SOFTWARE TO RESET BIOS PASSWORD. ALL YOU HAVE TO DO IS SIMPLY OPEN YOUR SYSTEM UNIT. UNPLUG ALL CABLES ON IT. GROUND YOURSELF BY TOUCHING @ LEAST 10-15 SECONDS TO THE SYSYTEM UNITS COVER ( SO-CALLED CPU BY SOME) ON YOUR MOTHERBOARD, LOCATE THE CMOS BATTERY, REMOVE IT.
Option #1: Mechanically Removing the Password Most motherboards manufactured over the last decade or more use a battery to sustain the dynamic Bios/CMOS settings for the motherboards PROM chip. These dynamic settings are those manually set by either the computers manufacturer or you, the user. There are two ways to erase these dynamic settings, by either resetting a jumper on the motherboard itself (referred to as a "clear CMOS" jumper), or by physically remove the power from the computer (disconnecting the power plug) and then removing a battery (used to maintain power to the PROM chip that contains the Bios/CMOS information) from the motherboard.

The procedures for clearing a Bios/CMOS without jumpers is essentially the same as those given above when they are present, it just takes a little more effort.
  • Shut down the computer and disconnect the power plug.
  • Locate, if possible, the instruction booklet for your motherboard. If you cannot locate the booklet, then user the motherboard references on this site to locate the manufacturer and see if a manual is available there. You may also want to closely examine the motherboard itself.
  • Now identify where the battery is located on the motherboard. It will be approximately 1/2 inch in diameter.
  • Normally these batteries are held into place with one or more small clips over the face of the battery. Carefully lift the battery out of its socket and set it aside. Note: Some batteries are actually soldered to the motherboard, so take that into consideration and be careful.
  • Leave the battery our of the computer for about 20 to 30 minutes and then return it to its socket.
  • Now plug the power cord back in and restart the computer.
  • When the computer begins it's startup (boot) process, tap the DEL, F10 or F1 key, (whichever is appropriate for your computer) to get into the Bios/CMOS setup. If you need more detailed information as to how to get to the Bios/CMOS setup, follow this link. Bios Basics
  • Once into the Bios/CMOS setup, look for a section or area to set the Bios/CMOS to its default settings. This will return the motherboard to either its basic or optimum settings depending upon the motherboard manufacturers settings. You will then need to verify certain settings, such a CPU and memory as well as hard drive type and size recognition. If you need more information regarding these settings, follow either of these links: For an AMI Bios or for an Award Bios.
  • After making any final adjustments, save your settings and restart the computer. The Bios password should be gone and the Bios set to its optimum settings.

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.
