How to Reset a BIOS Password.


Desktop Machines.

In desktop machines its very simple.
Just remove the BIOS Battery from the motherboard and place it back after 1mint.

Laptop Machines.

It is some what difficult in laptop machines. Because it is not an eassy job to remove BIOS battery from the mother board. So i'm just explaining some most commen methods.
1. Using a Backdoor BIOS Password

The backdoor password is a BIOS password that works, no matter what the user sets the BIOS password to. These passwords are typically used for testing and maintenance. Manufacturers typically change the backdoor BIOS passwords from time to time.

AMI Backdoor BIOS Passwords Reported AMI backdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW, BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords One reported Award backdoor BIOS password is eight spaces. Other reported Award backdoor BIOS passwords include 01322222, 589589, 589721, 595595, 598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARD SW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT, CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332, J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz, TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
Phoenix Backdoor BIOS Passwords Reported Phoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, and PHOENIX.
Backdoor BIOS Passwords from Other Manufacturers Reported BIOS backdoor passwords for other manufacturers include:
Manufacturer BIOS Password VOBIS & IBM merlin Dell Dell Biostar Biostar Compaq Compaq Enox xo11nE Epox central Freetech Posterie IWill iwill Jetway spooml Packard Bell bell9 QDI QDI Siemens SKY_FOX SOYO SY_MB TMC BIGO Toshiba Toshiba Remember that what you see listed may not be the actual backdoor BIOS password, this BIOS password may simply have the same checksum as the real backdoor BIOS password. For Award BIOS, this checksum is stored at F000:EC60.

2. Resetting the BIOS Password using Software :

!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.

CmosPwd will recover the BIOS password for the following BIOS versions:
  • ACER/IBM BIOS
  • AMI BIOS
  • AMI WinBIOS 2.5
  • Award 4.5x/4.6x/6.0
  • Compaq (1992)
  • Compaq (New version)
  • IBM (PS/2, Activa, Thinkpad)
  • Packard Bell
  • Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
  • Phoenix 4 release 6 (User)
  • Gateway Solo - Phoenix 4.0 release 6
  • Toshiba
  • Zenith AMI
3. Resetting the BIOS Password using Hardware :

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.
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.

4. Vendor Specific Solutions for Resetting the BIOS Password :

Resetting a Toshiba BIOS Password KeyDisk will reset the BIOS password on Toshiba laptops.

Some Toshiba's can be convinced to bypass the startup BIOS password if you hold down the <LEFT-SHIFT> key while booting the system.
Resetting an IBM ThinkPad BIOS Password For information on how to recover an IBM Thinkpad BIOS password, please refer to How do I reset an IBM ThinkPad BIOS password?
Resetting an IBM Aptiva BIOS Password Some IBM Aptiva's can be convinced to bypass the startup BIOS password if you press both mouse buttons repeatedly while booting the system.

The easy way to clear the bios password and reset bios is to take out the bios battery and start computer for about 10 seconds and then turn it back off and replace the battery. When you turn it back on you may need to go into the bios and reset everything the way you want it, and don't forget to rest the time and date.

Reset bios password


Hi, its very easy to reset password for bios.

You have two methods to rest on two different conditions.

First if you want to re-set in normal mode and a second thing if you have forgotten the password.

First of all enter into Bios Setup then Security and Reset your password.

Second if you have forgotten your password and you need to reset without power on your computer take these steps;

1. Uncover your computer
2. See a jumper near to hard connector. This jumper sets on two legs total of three and one leg free.
3. Changer jumper side ... It sets on free leg and then one leg will free.
4. Now, starts on your computer, it will give you a message. Now follow the message and accept changes for Bios and press enter.
5. Once again switch off your computer.
6. Reset jumper on the same place and cover your computer again.
7. Start your computer enter into Bios without any password. Now you can set your password from security tab again.

Wish you Good Luck

Intel bios supervisior pass reset with open system case


BIOS Password is stored in CMOS and retained by power provided by the CMOS (Coin-cell) Battery.
To Reset the BIOS Password, Remove the CMOS (Coin-cell) Battery from the motherboard for five minutes and restart the system. This will load the factory default settings and the password would be gone. Re-install the battery after the password is rest.

GoodLuck!

I lost the bios of my toshiba G30 qosmi now it gives me only black screen there is no boot at all ...how i can rest the bios back again is there is any manual way to rest it ?


To reset the BIOS password you need to open your laptop to get the battery. Remove first the keyboard and screw the open the back cover of your laptop. You can see there a battery like the battery of a clock but it too large. Remove it for almost 1 seconds and put it back
If the BIOS password have there you need to hook up the CMOS jamper.

I forgot the security password


here are 2 password type first 1 is bios password if tell me about your bios password it prompt when u powerup follow procedure below

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.
Then it not want password.

And if u tell about windows password
Then when you power up the computer press F8 key then enter in safe mode then wait until it prompt for user password

then enter in administrator then if u able to enter then reset your password.
But if u set and forgot default administrator password then u should need winxp recovery disk.
