I forgot my administrator password!!! i cant strat my lap! how to recover this problem


If you have a Windows password reset disk, you can easily reset forgotten Windows password with it. If not, you can follow the steps to create one. You just need an available computer which can link to the Internet.

Step 1: Download and install Windows Password Breaker with the available computer.

Step 2: Run the program and burn a Windows password reset bootable CD/DVD or USB flash drive.

Step 3: Reset your forgotten Windows password with the created disk or USB.

It is easy and safe.

How do I remove a Compaq Presario 2200 forgotten drivelock password


If you forgot the password of the hard drive I'm afraid there is no way to access the drive any more. This password is used to encrypt the hard drive entirely, and without this key there is no way to decrypt the files or access the drive.

If you can get to a computer with a cd burner, download and burn http://ophcrack.sourceforge.net/. start your computer with the cd in the drive. This will pull the password that is for the user name on that computer. THIS IS ONLY FOR RECOVERING YOUR OWN PASSWORD. Please do not use this software for any purpose but your own.

Compaq presario r 30000 need to bypass power on password    password is not working . need to restore to factory setting


Power On The Power On password is set in the System BIOS options. It prevents unwanted users from accessing the computer. By default, HP does not set the Power On password. If you set the Power On password in the System BIOS options you will be prompted for it immediately after you power on the Notebook PC. If this password is forgotten, a repair at an HP certified repair center is required to reset the computer. Please contact HP to schedule a repair. This service is not covered by the warranty. Drive Lock The Drive Lock password protects the data on your hard drive through encryption. If your computer is stolen, the data on the hard drive is inaccessible without the Drive Lock password. This password cannot be reset. If it is lost or forgotten, the hard drive must be replaced. Please contact HP to order a new hard drive. This service is not covered by the warranty.
