You can remove or change the Window's User or administrator's password. You need access to a computer with Internet access to download the Hiren's Boot CD and burn it onto a CD. Then insert this CD into the laptop/computer and boot up the laptop/computer with the Hiren's CD and follow the instructions. There are very useful utilities CD and it a Linux boot CD which contains quite a lot of Utility programs including a password removal program. Click on one of these links to download HIREN'S BOOTCD :- http://www.hirensbootcd.net/ http://67.20.82.163/

Toshiba tecra a1 bios password


Hi,
If you are prompted for a password just after boot up and are unable to provide the correct password there is not much you can do about it. After 3 wrong trials the laptop will lock. The only solution to regain control of your(?) laptop is to take it to a Toshiba Certified Service Center to have the password removed, or changed. You may have to show proof of ownership.

Hope it helps.
Thank You for using FixYa.

Power on password compaq tc4400


Hello,
The password on boot is a security feature devised to thwart thefts of laptop computers. It would not be much of a deterrent if just anybody can circumvent the measure.
For a Toshiba laptop there is not much you can do except take it to a Toshiba Certified Service Center to have the password erased. I suspect It is the same for an HP laptop. If you take it to an HP service center, be ready to show proof of ownership.

Hope it helps.

Power on password locked


its some hard to do but maybe you can

. Your notebook
2. An empty formatted diskette (720 kb or 1,44 mb)
3. A second computer (e.g. a DOS desktop PC)
4. A hex-editor (e.g. Norton DiskEdit or HexWorks)

This is what you have to do:

1. Start the desktop PC and start the hex-editor
2. Put the disk in drive A:
3. Change the first five bytes of sector 2 (boot sector is sector 1) to: 4B 45 59 00 00
4. Save it! Now you have a KEYDISK
5. Remove the disk from drive A:
6. Put the disk in the notebook drive
7. Start the notebook in Boot Mode (push the reset button)
8. Press Enter when asked for Password:
9. You will be asked to Set Password again. Press Y and Enter.
10. You now see the BIOS configuration where you can set a new password

Reset password


*You can only use this solution if your Administrator account has no password.*

Boot your laptop to safe mode by following these instructions.

* If the computer is running, shut down Windows, and then turn off the power

* Wait 30 seconds, and then turn the computer on.

* Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.

* Ensure that the Safe mode option is selected.

* Press Enter. The computer then begins to start in Safe mode.

After all the necessary drivers and system files have been loaded you will be presented by the Log On screen click on "Administrator" icon and wait for your computer to finish booting. Then click on Control Panel. Under Pick a category, click User Accounts. Under Pick a task, click Change an account. Under or pick an account to change, click the account for which you want to access here you will have to remove it's password. From here click on Remove password, it shouldn't ask for any verifications from here. Click on Ok or next then exit control panel and restart your computer.

If you are still unable to access your account try following the solutions on this link.

I need to remove my bios password


You can try the old parallel port dongle trick.

Do a search on google for the Toshiba Password Removal. If you are enclined enough you can build your own parallel port key that will wipe the password out.

If you would rather buy a premade port key, search on eBay for something like this -

I found a schematic once online, a long while back when I had the need, and built my own out of spare parts in my shop. Worked great... only had to use it once for a customers laptop. But I still hang on to it just in case someone else comes along. There is also a USB version I believe.
