My girlfriend got this laptop givin to her by her grandmother, she had forgotten the admin password but had a guest acc set up so it was no biggie, BUT... now its full of junk needs defragged/cleaned and...


Hi Chris,

Trying to get into the laptop's BIOS settings by pressing F11 at boot will NOT get you into the Admin account of Windows.

You can download and burn a copy of Hirens Boot CD - read about it here: http://www.hirensbootcd.org/ This is FREE software. Do not pay for it if you find it elsewhere and are prompted for payment. You may of course, donate a sum if you find it useful.

Once you've got a copy, load into your CD drive and reboot the PC. Either set the BIOS to boot the CD first, or select the CD Boot if presented with an option to do so at boot time.

The PC will bypass Windows and provide options. One will deal with resetting passwords. You will not be able to learn the old password, but you will be able to create a *new* password instead. Select the Admin account for a new password and make it something easy to remember. Once complete, remove the CD and reboot. While booting, press F8 and choose Safe Mode boot. The Admin account should be shown for WinXP - enter the password you just created.

Got to the control panel, and change your GF's User Account to Admin Level so that she'll be able to do just about the same thing the actual Admin account can do, without having to actually logon as the Admin. You should only use the Admin account when you have to - she should use her account with Admin level access 99.999% of the time.

I hope this helps & good luck!

Forgot pass word on my compaq pc


Which password you are referring to, There are two types of password.
1. Windows Password
2. BIOS Password.

If you are referring to Windows Password, I Suggest you to Reinstall the Operating System to resolve the issue

Or if it is BIOS Password you need to Disassemble the laptop and remove RTC Battery which looks like a money penny and reinstall after few minutes. this will help you.
Hope this helps.

`What is the password for phoneix bios setup utility


Toshiba has been leading the pack in this kind of security for years now. The only way to reset the BIOS password on THAT laptop, is to send it back to Toshiba.


Now, do you know what Toshiba will do next? Toshiba will ONLY send the laptop back to the current registered owner.



So, here is what you do. If the previous owner registered their laptop with Toshiba,

THEY have to transfer the ownership to you... you can't do that. THEN, you can send it back to Toshiba to have the BIOS password cleared.

THEN Toshiba will send it back, repaired, to you.

You cannot jump the BIOS chip, since the password is not stored there, but rather it is stored in an EPROM chip that does not require electricity.

So you cannot even remove the CMOS battery to clear the password.


You cannot use a special program and a floppy disc, because that Toshiba will not access the floppy disc before it accesses the BIOS... and since you will hit the password first, you can't access that software to try to clear the password


or you might try


restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

Reboot the computer As the computer is booting repeatadly press the F8 key as the computer is booting


If done properly the user should get to a screen similar to the below screen.

Select the option for Safe mode command prompt only

Windows Advanced Options Menu
Please select an option:

Safe Mode
Safe Mode with Networking
Safe Mode with Command Prompt

Enable Boot Logging
Enable VGA mode
Last Known Good Configuration (your most recent settings that worked)
Directory Services Restore Mode (Windows domain controllers only)
Debugging Mode

Start Windows Normally
Reboot
Return to OS Choices Menu


Use the up and down arrow keys to move the highlight to your choice.


select safe mode with command prompt


Then type at the C:\> prompt: type

DEBUG

and hit Enter. You'll see a dash (-) at the DEBUG prompt. Now type:

o 70 2e

which will show as -o 70 2e at the DEBUG prompt. Hit Enter. Then type:

o 71 ff

and hit Enter. Finally type:

Q

and hit Enter one last time to quit DEBUG back to the C:\> prompt.
Now you're ready to reboot your PC, and press the appropriate key or key
combo (look it up in your motherboard manual if you don't know it) to access
your BIOS Setup.


Youll notice the password is gone.


if this fails try typing


At command prompt type debug
you will get a - prompt where you can type the following (<enter> means press enter, not type enter*)

A <ENTER>
MOV AX,0 <ENTER>
MOV AX,CX <ENTER>
OUT 70,AL <ENTER>

My Lenovo 3000 G400M Laptop's BIOS password was set automatically and unknowingly. I dont even know what password has been set. I tried a lot to reset it according to my knowledge, but all in vain. Please...


The easiest way to do this is to remove the keyboard and look for the bios battery. Unplug the laptop and remove the normal battery and then remove the bios battery for about 10 mins. Replace the Bios battery, replace the normal battery, plug the laptop back in and the password should be gone.
