How to reset or remove BIOS password


There are four common categories of solutions to remove or reset a BIOS password and here are the details on how to go about resetting your BIOS password.<br /> <br /><b>Manufacturer Backdoor BIOS Password</b><br /><br />Most of the BIOS makers have set a backdoor password on the older computer models. That is the master password for BIOS. To reset BIOS passwords first you need to check the manufacturer of your computer's BIOS. Most computers have BIOS include AMI, IBM, Award, and Phoenix. These are the most common BIOS. You can unlock your locked BIOS using this master password. It works, no matter what the user sets the password to. Many popular computer and laptop manufacturers such as HP and DELL lock the BIOS because they want to protect their machine's most sensitive areas (those areas which have warranty) from their customers. These passwords are usually used by computer technicians for testing and repairing. <br /><br /><b>Reset the jumper that holds the password<br /></b><br />Open the computer and locate on the motherboard the BIOS password jumper. The jumper is usually jumper 1 and often labeled as PSWD, PWD, CLRPWD, CLEAR, JCMOS1, CLR, CLEAR CMOS, PASSWD, or PASSWORD. Normally you would have 3 pins and to reset the password you just need to put the jumper on the 2 and 3 pins leaving pin 1 empty.

Problem: You do not have access to change the settings in BIOS? . Have bought a...


There are two passwords in BIOS. One is start up password, the other isBIOS setting password. If you have forgotten the start up password thatmeans you cannot open computer at all. Then the first method is theonly thing you can do. Other methods can use to clear setting password.
==①:Motherboard Battery Discharge==
The common way toreset start up password is discharge Motherboard Battery. Most of thecurrent motherboard BIOS is using the button batteries to provideelectric power.That means if there is no electricity, the informationit contains will be lost. When it’s on power again, BIOS will set backto its original state, of course, there will be no BIOS passwords. Butyou will lose your setting at the same time.
What we need to dois to power off computer, open the computer box, and then unplug thepower plug of the computer to make sure that it is no electricity atall. Then locate the white silver button battery on the motherboard.Remove the battery carefully. Perhaps 30 seconds later, put back thebattery.
After put back the computer box then power on, thesystem will prompt “CMOS Checksum Error-Defaults Loaded”. That meansCMOS errors detected during inspections, had been included in thesystem default, BIOS password cracking success!
On somemotherboards, the battery is soldered to the motherboard, making itdifficult to remove. If this is the case, you have another alternative.Somewhere on the motherboard you should find a jumper that will clearthe BIOS password. If you have the motherboard documentation, you willknow where that jumper is. If not, the jumper may be labeled on themotherboard. If you are not fortunate enough for either of these to bethe case, you may be able to guess which jumper is the correct jumper.This jumper is usually standing alone near the battery. If you cannotlocate this jumper, you might short both of the points where thebattery connects to the motherboard.
==② : Backdoor BIOS Password==
Eachmotherboard manufacturer has set a backdoor password in order tofacilitate the provision of technical support. The backdoor password isa BIOS password that works, no matter what the user sets the BIOSpassword to. These passwords are typically used for testing andmaintenance. Manufacturers typically change the backdoor BIOS passwordsfrom time to time.
AMI Backdoor BIOS Passwords
Reported AMIbackdoor BIOS passwords include A.M.I., AAAMMMIII, AMI?SW , AMI_SW,BIOS, CONDO, HEWITT RAND, LKWPETER, MI, and PASSWORD.
Award Backdoor BIOS Passwords
Onereported Award backdoor BIOS password is eight spaces. Other reportedAward backdoor BIOS passwords include 01322222, 589589, 589721, 595595,598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARDSW, 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
ReportedPhoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, andPHOENIX. Backdoor BIOS Passwords from Other Manufacturers Reported BIOSbackdoor passwords for other manufacturers include:
ManufacturerBIOS Password
VOBIS&IBM merlin
Dell Dell
Biostar Biostar
Compaq Compaq
Enoxxo11nE
Epox central
Freetech PosterieI
Will iwill
Jetway spooml
Packard Bell bell9
QDI QDI
Siemens SKY_FOX
SOYO SY_MB
TMC BIGO
ToshibaToshiba
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 realbackdoor BIOS password. For Award BIOS, this checksum is stored atF000:EC60.
==③: Software Crack==
There are a lotsoftwares to test systems or start up password, but they need to run onWindows. So it is only used to reset BIOS setting password.
!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
Ifall else fails, you might be going to lose some money for technician.But they will use these same methods, try hard by yourself.

I have a Wipro Laptop. His BIOS is Phoenix. It has a CMOS password. How shall I clear the password.\?


Hi Nayanranjani.

As you trying to reset the BIOS password, let me provide the required steps.

You may reset the BIOS password by just removing and inserting the CMOS Battery.

The CMOS Battery will have the Computer date, time and also the BIOS password saved in it.

Hence, removing and re-inserting the CMOS password will reset the BIOS password.

Once the BIOS password is removed, you may assign a new BIOS password.

Hope this helps.

Please feel free to ask further questions.

Acer extensa 4220 bios password


There's no way that we can determine the BIOS password of your laptop. But if you can disassemble your laptop and locate the CMOS battery you can remove the CMOS battery to reset the BIOS together with the password. After resetting the CMOS battery you will no longer be asked to enter a password for the BIOS when you turn on your computer. However, there are instances that even though you reset the CMOS it's still asking for the password, for this concern, the computer manufacturer should deal with this concern.
