SOURCE: Password forgotten

Unfortunately, there are only 2 ways around this. Reinstallation of te OS will wipe out everything but allow a new account to be created. If this is the case, create 2 accounts both with admin priveleges for future scenarios. Restore her important files from her backups ( she did backup on a regular basis, didn't she?).
If there are no backups and she doesn't want to lose what's on there, Google "password recovery software" and choose from the multitude of hits that are returned. I can't recommend any of them as I have never had to use them before.
Thanks for using Keep us in mind for future needs and please rate this tip accordingly.

SOURCE: Forgotten User Password

Try to get your hands on a windows installation disc, or even the recovery disc that came with the computer. If you get the windows installation disc, you can reinstall windows onto it. That is basically what you can do.

SOURCE: My friends laptop went daft last night and now she

OK, I'm assuming this is a power up password or BIOS password that has been forgotten. The only way to clear this password is by "shorting" a jumper connection on the motherboard. There is a special jumper on the motherboard where the Memory modules are. Flip the laptop over so the bottom of the case is up. There is an access door that covers the memory, take this door off and take the memory modules out. Look on the motherboard, there will be a small square marked J3 and it will have metal contacts on it. To "short" the connection, use a screwdriver or similar tool that will contact all the contacts in the jumper area. While holding this in place, power up the laptop and wait for it to go into the boot sequence. Once it boots or after 45 seconds, remove power and remove the "short". put memory back in and reboot. When you do this procedure, make sure the main battery is out. Once you reboot, it may still ask for the password, just hit enter and it should let you in.

Forgot log-in password

As your log in is personal to you, I would say you are the only one who can use it. There is no way of cracking it externally. Sorry.

I have forgotten my password for my elonex ebook

OK, if you are running Windows 7, Microsoft tightenedsecurity on it so you've got to have a password reset disk which 99% of thepeople who own laptops with windows 7 fail to do. It should be one of thefirst things you do when you buy the laptop. Otherwise, you're faced withreinstalling the Operating System or possibly doing a System Recovery.

If you're on Windows XP or Vista try this:

Turn off the computer, then hit the power button to turn it back on andimmediately start hitting the F8 key repeatedly until you see the Safe Modeoption. Select SAFE MODE and let the computer boot up. When it getsto the User Login screen it will show the Administrator userid and the useridfor which you forgot the password. Sign in as the Administrator (hopefullyyou didn't put a password on it and forgot it too). Once the desktopappears it will look different, the screen will be darker and the icons bigger,but this is normal for safe mode.

Click Start/Control Panel/User Accounts
When the User Accounts screen opens, click on the userid for which you forgotthe password. Select the option to REMOVE PASSWORD.

Reboot your machine.

Forgotten passwords are hard to fix unless you have the reset disk. I have yet to find a way to bypass the password screen on a Windows 7 PC.

I have a way of resetting your password if it happens in the future.
