Re: I HAVE THE TOSHIBA 4080XCDT AND I DO NOT KNOW ITS...
Go onto ebay.com and search for a LPT port password remover, to my knowledge you plug this litttle adapter into the Printer port on the back of your laptop and then turn it on and the password sshould be removed by it. You may want to research a tad to see if your laptop can do this.

Dear beanbean, This "lovely black screen" is a BIOS password screen. This shows up because somebody has set a boot-up password in the BIOS Setup. If you're lucky, the BIOS Setup is still unprotected, and you can access it as follows: When you turn it on, look for something that says "Press [button] to enter Setup" or "Press [button] to enter Setup Utilities." Press the corresponding button on your keyboard, and you should enter BIOS Setup.
Now two things can happen. Either you are permitted to access Setup, or you are prompted for the password. If you can access Setup, navigate to the Security tab and clear all set passwords.If not... then you can either reset BIOS by unplugging the computer, taking off the back, and removing the CMOS Battery (unrecommended), or you can call Toshiba support and ask for the master password (Most manufacturers have a master password, which will allow you to access Setup and remove the boot-up password) Hope this helps,Ericthecmh
No getting around this one... but you can make yourself a parallel port key and it'll remove the password on power up. Buy an old, parallel port printer cable, cut it, and wire it yourself. Here's the link to the wiring diagram:
Are you the one who set up the BIOS password? If not, unfortunately, there's no way for us to retrieved the password. The only way you can reset the password to default settings is to reseat the CMOS battery on the motherboard, its a circular thing that looks like a battery of a watch,sometimes a pin hold it, just detached it then wait for at least 30 minutes then connect it back again,
Note: Before you reseat the CMOS battery,make sure that everything is unplugged on the computer, like AC adapter,battery and all external devices...
Hope this will help...Thank you for using Fixya...
mairead_venk: From the online users guide that you can get to from here: (click here), it explains that there is some kind of power switch lock on the LEFT side of the notebook that you have to slide out of the way in order to be able to press the power button.
They have no pictures of the laptop on their user guide, so it's a bit difficult to tell you exactly the location.
You'll have to actually partially disassemble the machine. You need access to the motherboard to remove the CMOS battery so you can reset the password. If you are uncomfortable with taking the computer apart, better get someone to do it for you.
