i have a dell c400 and i set a password on it but then i forgot it i cant get into my computer and i need help to get into it anyone know?

is this a BIOS password? If so, u may be able to reset it by removing the lithum battery on the motherboard (careful!) and put it back in. ol tip i dunno if it will work for this. Or you reflash the bios.

Resetting CMOS by removing the CMOS battery, waiting a while, then replacing it should do the trick if it's a BIOS password. Make sure you shut the system down and switch off at the wall outlet before fiddling about inside the case.

nah its the windows password.. like i turn on the computer then it turns on fine and everything but when windows open i have to put in the password.. yeahh.. i forgot that.. anyway i can get in?

Boot into 'Safe mode' and log in as 'Administrator'.

Copy the data files across to somewhere else, delete the user account, and then create a new one, making sure you keep a record of any password this time. (If you've enabled "Make my folders and files personal" or whatever the option is, you might be out of luck )

Fair dinkum, I reckon a lot of the time people just use the password feature because it's there! If it's not important enough to keep a record of the password, then why set one?

the thing is.. all i want to do is format my computer.. haha thats about it..

If you want to reformat your system drive, you won't be able to do that when booted into the Windows installation on your drive anyway- you'll need to boot from a Windows install CD and you will then be able to choose to reformat your drive as part of the installation process.

the thing is.. the laptop doesnt come with floppy or CD-ROM i have this external DVD burner (usb) and i plugged it in.. and it cant read it.. other than buyin the thing that comes wit it any othe way i can do it?

No CD or floppy drive?? Unless you can get the laptop to boot from that DVD drive you're kind of stuck.

You should be able to boot off the usb DVD burner, you should only have to set it up in bios, there is a bootable linux floppy, that you can burn to a bootable cd, that works well to set the password to nothing, or if you have the access or money ERD commander is a good program also.
