Most Toshiba laptops CMOS and pswrd can be reset by shorting two jumpers marked "B500" located in the RAM module area while booting from cold start.

Did you try resetting her password from another administrator account? (control panel > user accounts > manage accounts_)

 

If there isn't an admin acc. to do this

 

Try Ophcrack... it can retrieve most windows login passwords.

 

There are other ways too, all is far from lost.

Did you scrape the covering varnish off the B500 contacts? Be careful as to not damage the MB or solder.

Ophcrack works as previous member suggests for accessing system passwords; but BIOS password will be unaffected. If the HDD has password; forget about it; replace the drive and reinstall.

When does the machine ask for password? Before BIOS screen, after or to log in to Windows?

here's an easy way to remove it if you don't have luck, or don't want to use Ophcrack.

 

http://comphacks.wordpress.com/2010/09/03/remove-the-password-of-user/#more-60

 

or you can always use a Linux live CD and just move the information you need out of the profile into a new one...

 

there's more tricks if these don't help...

 

EDIT: I just read that article, seems overly complicated for what it is, rather.

 

1.Search for cmd, right click it and Run as Administrator.

2.type:  net user username *

 

done, no more password on username.

There is a tool that OP may want to consider familiarizing him/herself with. Parted Magic was one of the major tools that got me rolling. Powerful and user friendly. Free and can do wonderous things to a computing machine; including manipulating passwords. Also data recovery, hardware-testing, creating/resizing/moving partitions and recreating partition tables. Imaging and cloning of hard drives are a snap and the back-ups reliable. The list goes on....

Never. The only issue I have ever had with Parted Magic is the ClamTK virus scanner; could never get it to scan successfully anything. I could update the definitions but can't get it to work. No need though as there are many ways to remove malware.

Update - when daughter was away at school in UK they replaced the keyboard with a UK version.  She reset her password using keys not found on a US keyboard.  It has been working fine for the past few weeks with new password.

 

So I booted while pressing F8

 

Selected system repair - password request comes up with a select keyboard input option.

 

I select key board for UK extended version and her password worked and allows me into system recovery options. (Start up repair, sys restore, sys image recovery, windows mem diag, command prompt and Toshiba rrecoovery wizard).

 

I tried to reboot and log in again normally hoping that reset something but her password would not work on normal Windows 7 login screen.

 

Any thoughts?  In recovery options above is there a way to change the password so we can reset it without UK components.  Or a way to set the keyboard to UK reboot and maybe then the normal windows 7 screen input will work?  I have recovery disks but am reluctant to use them given the keyboard change.

 

She says she has been using it for weeks and there has been no issue - just all of a sudden had a problem couple days ago.

 

Thanks for your help

the shorting did nothing - i did scrap the leads and tried again  - still no.

 

If i try the option with the command prompt and type:  net user username * 

 

will i be able to set a username later if i get the keyboard sorted out?

 

I did not want to try anything yet without letting you know about the keyboard status.

net user username * from the Administrator command prompt forces you to change your password without knowing what the old one is... So any old password will be gone.

 

replace username with the computer username you want to unlock.

Would one need to switch keyboards before typing the new password? Would it not be easier to clear/remove the password completely?
