When computer turns on I have black screen with blue text box asking for password

My computer froze up on me so I took out the battery and when I plugged it back in the only thing that comes up is this black screen with a blue text box asking for a password, The password I use for my windows does not work so don't know what password it is asking for. Assuming and hoping there is a universal password for this problem but couldn't find anything in the manual.

One of your friends might have set this up... I've done it before. You either got a crazy virus or somebody played a joke on you. Probably the latter.

Toshiba laptop has black screen WITH BLUE password box how do i get past the box to get my laptop back/i've tried tons of different f keys and even took out the battery please help


If you did not set a password, first try by simply hitting enter (no words or characters in the box). If this does not work, restart the computer and press F11 or F12 to enter set up (only one or the other will bring you into setup). Once in setup, find where to set\change password. For "new" leave blank, and press enter. Delete anything that may be in this box. Do the same for the next box(es) for "re-enter" password; leaving the box blank and pressing enter. At the very end (right) of the screen, it should give a list of exit options (after selecting "reset" or "save" password; select "save changes and exit" option. The computer should restart automatically and bring you to either 1. The "blue" password screen, for which you will press enter. 2. The operating system Desktop, i.e. Windows etc. where all your icons and apps are displayed. If thus does not work, you need to reset the computer to its default (factory settings) which can be done following the same steps, and finding this option in the menus provided. I do not know what OS you have, but if it is Windows then the above is where to go.

Black screen blue box saying


some one must have put in a boot password to your laptop,
follow this:
When booting up, enter your BIOS setup (usually by pressing the F2 key at the appropriate time).

Locate the BIOS Password section and turn the ON STARTUP password to off. There is no standard setup for BIOS, so I can't give you exact instructions.

If this does not work, try:
remove cell & start your pc you will here beep...beep...beep...

then turn off your pc & restore your cell.Start your pc and
password is removed.

there is a battery on motherboard,a button cell,you can try removing that and start computer, then put it back, bios settings will be lost.
you can also try removing any hardware like ram,if you have two,when system is off,turn on , it will prompt for changes , enter bios and try remove password.

It's asking me for a BIOS password, it's a Black screen, with a blue box with white lines, It only says "Enter Password" and after three tries, it shuts down. We don't have any idea what the...


The bios password only appers when you press F2 or Del upon powering it ON, so don't press anything when turning it on.

the bios password can be reset and remove its previous password by opening the laptop and remove the CMOS battery inside it, not the physical battery of the laptop, the CMOS battery is a 1inch round battery inside a laptop and computer.

You need to break the password and log into the computer again.

Black screen ask for password


Black screen with "Enter Password" in blue box. - BIOS password.
To reset: take the CMOS battery out then place it back again.

Black screen with Enter password in the upper right left corner - could be hard disc password.,
If you set up the password before, you can only bypass that by entering the correct password. If not, it will render the hard disc useless.
