LAPTOP AND NOTEBOOK RECOVERY |
Most laptop manufacturers have provided additional safeguards for their computers. We are not aware of any simple BIOS recovery program that works on laptops, nor are we aware of any simple backdoor passwords for these machines. BIOS passwords in most laptops are stored in a special chip on the motherboard and the only way to bypass this password is to replace this laptop security chip. Laptop BIOS passwords cannot be bypassed or reset by removing or shorting the CMOS battery. Further, doing this may cause other system errors and complicate the recovery or your system. |
We offer a full-range of replacement laptop security chips. These chips will allow you to bypass the laptop BIOS password. Note that these chips will require soldering on the system board (a hot air soldering kit is also available.) Since these chips store the laptop BIOS passwords, replacing the laptop security chip will remove the BIOS password. However, if a hard disk lock password has been set, it will remain. Passwords can be recovered from the original chip removed from the system board using our Password Recovery Service (PRS) for an additional fee. Since the BIOS password and hard disk lock passwords are usually the same, recovering the BIOS password from the old chip may allow you to access the hard disk. However, this is not guaranteed, since these passwords can be set independently. All replacement chips include detailed instructions. Password Crackers, Inc. cannot take any responsibility for damage to system boards, computers or data. More information about our security chips and our chip password recovery service are available on our security chips page.
HARD DISK LOCKS |
Some laptops provide a utility to lock a hard disk with a password. These passwords are not the same as BIOS passwords. Moving a locked hard disk to another machine will not unlock it, since the hard disk password is stored in the hard disk firmware and moves with the hard disk. Also, adding a new (unlocked) hard disk to a locked machine may cause the new hard disk to become locked. Also, note that hard disk lock passwords cannot be removed by reformatting the disk, fdisk or any other software procedure (since the disk will not allow and reads or writes to the disk, it cannot be reformatted.) Usually, the BIOS password and hard disk lock passwords are set the same by a user and we can recover the BIOS password directly from the laptop security chip (after it is removed from the system board.) However, it is possible that the BIOS password and hard disk lock passwords may be set different. In this case the BIOS password will not unlock the hard disk. You can test to determine if your hard disk is locked by attempting to access it in another laptop. Password Crackers, Inc. offers a service that can unlock most models of laptop hard disks. Detail are available on our hard disk page. |
