Toshiba C655D-S5133 system unit I turn it on an it asks for a password, I forgot the password it shuts down after three times of entering the wrong password.

Dead battery? Try another cord/charger with the EXACT same power specs.

So this is asking for a password at boot up?? Sounds like the Admin/System password is enabled.

Try this:

1. As the computer is booting press F1, F2, or Del to enter CMOS setup.
2. In CMOS setup when prompted for a password, guess three times until you're giving the code. If after entering the wrong password three times the computer is displaying a 5 to 8 code, as shown in the picture, continue to the next step.
3. Write down the code and visit Dogbert's BIOS Password Backdoors scripts page to download Python and the free Python scripts to clear many of these types of passwords.

Hi,

I will advice you buy Toshiba Satellite C660-12H because the battery last longer and some other features are attached to it.

When you restart it, should say something like "Press F11 for system recovery." It might not be F11, but it will be one of the F keys. It will tell you which one during startup.

it sounds like you are infected with a virus or Malware.

To reset the BIOS read the information from this link.

In case of your Toshiba laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Toshiba has had a problem with their laptops locking out the system with a BIOS password. They are providing support for some of their users if you call them by Oct 31 2010. I have been able to get 2 laptops fixed by Toshiba because of this problem.

The down side of this is that you have to send them your laptop so they can do the repair.

Hope this helps

Hello,

When you installed the system, you entered a BIOS password.
There is nothing you can do to bypass that password. The only solution is to take laptop to Toshiba Certified Service Center to have password disabled.

Hope it helps

1. At the BIOS password prompt ("PASSWORD = "), press and release the following keys, one after another:
Ctrl, Tab, Ctrl, Enter
The computer's response should be:
PC Serial No.= XXXXXXXXX
Challenge Code= XXXXX XXXXX XXXXX XXXXX XXXXX
Response Code=

2. Get response code from your local toshiba support center
Then follow the instructions the support guy will give you to unlock the laptop

I dont know which password you asking about but:

if the password is in setup utility of system then you have to reset the bios & if it is of windowsXP then press ALT+CTRL+DEL 2times then it will ask for username and password,
TYPE
username: administrator
password:

no password and press enter if the system still say wrong username & password then it means you have to format & reinstall it if you also forgot administrator password.
