How to bypass or crack the Bios password.?

Question

My son died about a year ago and I want to give his laptop to his sister, but he had a BIOS password installed. How can I clear the password so my daughter can use the laptop?

Answer 1

There are two passwords in BIOS. One is start up password, the other is BIOS setting password. If you have forgotten the start up password that means you cannot open computer at all. Then the first method is the only thing you can do. Other methods can use to clear setting password.



==Step1:Motherboard Battery Discharge==

The common way to reset start up password is discharge Motherboard Battery. Most of the current motherboard BIOS is using the button batteries to provide electric power. That means if there is no electricity, the information it contains will be lost. When it’s on power again, BIOS will set back to its original state, of course, there will be no BIOS passwords. But you will lose your setting at the same time.



What we need to do is to power off computer, open the computer box, and then unplug the power plug of the computer to make sure that it is no electricity at all. Then locate the white silver button battery on the motherboard. Remove the battery carefully. Perhaps 30 seconds later, put back the battery.



After put back the computer box then power on, the system will prompt “CMOS Checksum Error-Defaults Loaded”. That means CMOS errors detected during inspections, had been included in the system default, BIOS password cracking success!



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.



==Step2 : Backdoor BIOS Password==

Each motherboard manufacturer has set a backdoor password in order to facilitate the provision of technical support. 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

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.



==Step3: Software Crack==

There are a lot softwares to test systems or start up password, but they need to run on Windows. So it is only used to reset BIOS setting password.

If all else fails, you might be going to lose some money for technician.

But they will use these same methods, try hard by yourself.

Answer 2

The BIOS information is maintained using a watch style batter on the motherboard. With the PC turned off and disconnected from power (unplugged), remove the outer shell.



Pop out the battery and leave it out for a couple of minutes to let all capacitors discharge. Then return the battery and put the PC back together.

Answer 3

Well, the satisfactory solution to crack it's via taking out and placing again the battery. If you dont desire to try this, you'll be able to do this (Vista handiest I suppose) however its now not precisely finding out the password. This handiest offers you entry to an Administrator account however no less than you get SOMETHING. one million. Go in your Start menu and proper-click on at the “My Computer” icon. two. Choosing “Manage” from the record will immediate a User Account Control (UAC). three. When you're performed, the “Computer Management console” will seem. Expand the “Local Users and Groups” alternative with using the arrow subsequent to it and prefer “Users” folder. four. You can now prefer the “Administrator Account” and cross to the “Actions” panel to open “More Actions”. five. Choose “Properties” to open the “Administrator Properties” conversation field and uncheck the alternative categorised “Account is Disabled”. 6. When performed, click on “OK” to verify alterations. 7. The Administrator account will have to now be gift in your log in reveal.

Answer 4

Hi,



Locate and remove the bios battery then replace it, that should clear it.



Or take the laptop to a computer technician and he will do that for you.



Also if you have the make and model of the pc then search the net for a users manual and see if there instructions in there.

Answer 5

There is a jumper that is located close to the battery. Remove the jumper and change the jumper settings. Power up that way, and it will clear the BIOS password.

Answer 6

You have to remove the CMOS battery for about 10 seconds, note this isn't the normal battery, it will be located under a cover on the base, or under the keyboard, depending on the make and model.
