Assuming your laptop is running Windows Vista there are two ways to remove the password.

If he created a password reset disk or USB key you can click on "Reset Password" below the password entry box.

Otherwise, you will have to use 3rd party software to bypass login security.

It is easier and more effective just to erase the password rather than recover it. The best free tool available is called the Offline NT Password & Registry Editor. You will need another computer with a CD burner.

Download the CD image here: http://pogostick.net/~pnh/ntpasswd/cd100627.zip

Burn the image to a disc.

Put the disc into the laptop and boot off of it. It may boot up automatically, otherwise use the boot menu by hitting a key during the HP logo after powering the computer on. This will either be Esc or F9 on most HP laptops.

Wait for everything to load until you see something like this:
1 : /dev/sda1 40958MB BOOT

Please select partition by number or
q = quit
d = automatically start disk drivers
m = manually select disk drivers to load
f = fetch additional drivers from floppy / USB
a = show all partitions found
l = show propbable Windows (NTFS) partitions only
Select: [1]

You should be able to just hit enter to choose the default selection. Next you should see something like this:

=========================================================
¤ Step TWO: Select PATH and registry files
=========================================================
What is the path to the registry directory? (relative to windows disk)
[WINDOWS/system32/config] :

Again, the default should work fine so just hit enter. Then you should see this:

-rw------- 2 0 0 262144 Feb 28 2007 BCD-Template
-rw------- 2 0 0 6815744 Sep 23 12:33 COMPONENTS
-rw------- 1 0 0 262144 Sep 23 12:33 DEFAULT
drwx------ 1 0 0 0 Nov 2 2006 Journal
drwx------ 1 0 0 8192 Sep 23 12:33 RegBack
-rw------- 1 0 0 524288 Sep 23 12:33 SAM
-rw------- 1 0 0 262144 Sep 23 12:33 SECURITY
-rw------- 1 0 0 15728640 Sep 23 12:33 SOFTWARE
-rw------- 1 0 0 9175040 Sep 23 12:33 SYSTEM
drwx------ 1 0 0 4096 Nov 2 2006 TxR
drwx------ 1 0 0 4096 Feb 27 2007 systemprofile

Select which part of registry to load, use predefined choices
or list the files with space as delimiter
1 - Password reset [sam system security]
2 - RecoveryConsole parameters [software]
q - quit - return to previous
[1] :

Choose the default option to reset the password. You will then see a list of users like this:

===== chntpw Edit User Info & Passwords ====

' RID -'---------- Username ------------' Admin? '- Lock? --'
' 03e8 ' admin ' ADMIN ' '
' 01f4 ' Administrator ' ADMIN ' dis/lock '
' 03ec ' grumf1 ' ' '
' 03ed ' grumf2 ' ' '
' 03ee ' grumf3 ' ' '
' 01f5 ' Guest ' ' dis/lock '
' 03ea ' jalla1 ' ADMIN ' *BLANK* '
' 03eb ' jalla2 ' ' *BLANK* '
' 03e9 ' petro ' ADMIN ' *BLANK* '

Select: ! - quit, . - list users, 0x - User with RID (hex)
or simply enter the username to change: [Administrator]

This time you need to type in the username which needs the password reset, and hit enter. Then you will get these options:

- - - - User Edit Menu:
1 - Clear (blank) user password
2 - Edit (set new) user password (careful with this on XP or Vista)
3 - Promote user (make user an administrator)
(4 - Unlock and enable user account) [seems unlocked already]
q - Quit editing user, back to user select
Select: [q] > 1

Choose option 1 and press enter. If it was successful you should see this:

Password cleared!

======== chntpw Main Interactive Menu ========

Loaded hives: <sam> <system> <security>

1 - Edit user data and passwords
2 - Syskey status & change
3 - RecoveryConsole settings
- - -
9 - Registry editor, now with full write support!
q - Quit (you will be asked if there is something to save)


What to do? [1]

This time you can choose option q to quit. It will then ask you to save changes:

=========================================================
¤ Step FOUR: Writing back changes
=========================================================
About to write file(s) back! Do it? [n] : y

Type Y and hit enter. You can now reboot the computer and take the disc out.

Your password should now be reset and you can create a new one in the control panel. For more documentation on this tool go to the website here: http://pogostick.net/~pnh/ntpasswd/

    This solution is for a Windows login password, not a BIOS password. The question wasn't entirely clear which one you needed reset.

You need to remove the access panel on the back of the laptop, locate the jumper labeled E49 and remove from positions 1 and 2 and put it on 2 only. Replace the cover and boot up, this should get you past the password.

Please leave feedback if you find this helpful. Thanks.

Http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01039180/c01039180.pdf
Page 54 of the manual describes, in detail how to remove the BIOS battery.
And, here's some more instructions.
1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.
2. Remove the access panel.
3. Locate the header and jumper labeled E49.
4. Remove the jumper from pins 1 and 2. Place the jumper over pin 2 only, in order to avoid losing it.
5. Replace the access panel.
6. Plug in the computer and turn on power. Allow the operating system to start.
NOTE: Placing the jumper on pin 2 clears the current passwords and disables the password features.
7. To re-enable the password features, repeat steps 1-3, then replace the jumper on pins 1 and 2.
8. Repeat steps 5-6, then establish new passwords.

Hp 530 power on password solution please


HP website ... So long as you make sure you get to the exact correct product (which sometimes seem hard or not specific) I have the HP530 and fortunately I finally got it right. In the solutions section I recall seeing a .pdf file with an answer to the power on password solution. I didn't download it, since I don't have that problem. I have had great success with the .pdf solutions on the HP site directly.

Toshiba satellite laptop lockout


is it a windows password or poweron password? you must be wondering what are they?
windows password is when you have to enter the password to get into windows and before that you get to see the windows loading screen.
poweron password is hard to crack, it will ask a password on a black screen saying Enter a Password, and the background will be completely black in color.
if its a windows password, press the "Alt+Ctrl+Del" twice, you'll get a screen which will ask you a username and password. in the username and password type in, "Administrator" and password will be blank. hit enter. if it works, then for the rest of the steps, mail me at L2support.hp@gmail.com

I forgot my password for my hp 530 laptop


You need to reset the BIOS, which is sorta like a manager for the computer. Some pretty basic settings may get trashed -- like whether it automatically comes back on after a power failure, hard-coded power management things, that sort of stuff -- but it should be fine.

Directions are available on Page 30 of this document:
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01039180/c01039180.pdf?jumpid=reg_R1002_USEN

See that part where it tells you to look on Page 54 for removing a Real Time Clock battery? There is a -lot- of disassembly involved in this. Read through all the relevant instructions. You'll probably want to print pages 30 to 55 of the PDF for everything you need to take apart ... which is just about everything between pages 30 and 55. If you're not comfortable doing that, you may wish to hire someone -- it may be cheaper to find a local guy than a mail order company, which seem to prey on panicky business people and charge exorbitant rates. Shop around and get quotes.

I have a compaq evo n400c needs a power on password key


If you forgot your password then you have to take your laptop to hp service centre. Because the laptop need to be disassembled before one can reset the poweron password.
