Question about Dell Latitude C640 Notebook

Laptop asking me for a password but was never password protected

My Dell Latitude C640 has locked me out. I cannot get access to my files or anything on the computer. It is asking me for a password and username but the laptop was never password protected since I am the only one who uses it. Rather than the usual screen that comes on to log in, it is a Windows XP screen that comes up w/o a picture and asks me to log in. Any suggestions how to reset it or get the usual screen to come on and log in?

Just use oph crack, use it to find a password/username then go to control panel, classic view in the top left corner, user accounts, "change the way you log on and off" then select the "welcome screen" option. if this happens still, you might be pressing a "lock" buttom to turn your pc off.

Unlock password protected Dell C640

If it is a passwd set in the bios...good luck. You may have to download a disc from
If it is a windows passwd after the dell splach screen tap F8 this brings up the Advanced Startup Menu. Select safe mode and log in as the administrator. From there you can remove or change the password for all accounts. If there was never an account setup on that laptop and the Administrator account is being used then you will need a disk fron to retrieve that password.
