How to crack a notebook password

Toshiba Notebook Password crack

For laptops, it is best not to set the password easily, because the laptop's power-on password is not like a PC stored in the CMOS circuit can be discharged through the discharge, the current newer notebooks are stored in the main board of several logic circuit, we can not crack the individual (this series of computers, The password can add to three layers, each irresolute leng cheek file round Huang  to fascine  curled Pomelo mei  descurainiae the scene of file choke?..... A computer is a device, it may take a lot of money (at least hundreds of) to break it.

But for the older laptop, you can try the following methods, you may be able to remove the laptop boot password: First, change the hardware configuration of the machine, such as the hard drive down, and then reboot may automatically enter the Setup program, and clear the power-on password. Second, you can try to find a chip on the motherboard, this chip is commonly known as 818 chip, generally "MC146818" has 24 pins, short to 12th foot and 24th foot 1 seconds, or to find a labeled "MC14069" chip, the 14th foot to the ground short, you may be able to achieve the purpose of cleaning up the password.

For Toshiba laptops If you forget your password, you can use the Password service floppy disk to solve (password service floppy disk in every time you set or modify the power-on password to generate, please properly save). The steps are as follows: Insert the Password service floppy disk in the drive. Press ENTER to receive the following message: Set pass Again? (y/n) Press Y to run the Tsetup program and set a new password. Press N to restart the computer.

Note: The password service floppy must be inserted into the drive, otherwise the display will return to password=. If you have inserted a floppy disk in the drive, the message still appears and the password service floppy disk may be problematic. Also note the following two issues when using password service floppy disks: If the BIOS boot priority is set to the hard drive or the optical drive, press the reset button to keep the F key pressed to ensure boot from the floppy disk drive. If the computer is in recovery mode, the password service floppy will not work when the power is turned on. At this point, please press the reset button first.

For older Toshiba laptops, there is a "backdoor" to the BIOS password protection. You can try the following methods, perhaps bypassing the Toshiba notebook BIOS password limit without entering any password authentication. Prepare a formatted, empty floppy disk, another computer, a binary editing software (such as Norton Diskedit or Utraledit 32, etc.). The specific steps are as follows:

1. Start another computer, open the binary editor, the floppy disk into the drive, modify the first 5 bytes of the floppy disk, make it into: 4 B 45 59 00 00, note that the boot sector is the No. 0 sector, do not change the wrong. Then save the changes and you will now have a key plate. Insert this floppy disk into the floppy drive of the notebook computer, press reset key to restart, when prompted to enter the password, press ENTER directly, the system prompts you to set the password again. Press "Y" and enter. Then you see the BIOS setup interface and you can reset a new password.

2. The notebook computer is Toshiba, can conveniently use the computer itself the print mouth to clear the password.
