How do you reset the BIOS password

Brandenburg · Feb 25, 2011

Here is the deal.. My daughter in her infinite wisdom, decided to set the supervisor password on her laptop and FORGOT the password :facepalm: :banghead:

.. the model is a Toshiba Satellite L305-S5955..

Been nice if she would of written it down somewhere

OK.. So any ideas..

im asking her now via facebook to get a more accurate date

1 Have a look at the manual and Toshiba website in their support section for help.
2 BIOSes are cleared of passwords by removing the CMOS battery for a bit and usually moving a link to the "clear" position. It's not always easy to do this on a laptop of course, as you may have to take it apart, hence step 1 above.

EDIT: crikey, that was fast! I started writing when there were no answers and by the time I clicked the post button there were several! I think this must be quick even for TPU.

Try left shift key at power on before attempting a cmos clear.

Yea.. so i figured.. GOD,i hate laptops.. PC's are no problem...

Ask her if it's got a parallel port, if so you're in luck. Link her to a pic of a parallel port.

If there's no parallel port, I noticed Hirens BootCD has a tool that might be useful (cmospwd).

OK she told me its like 2 to 3 years old.. thought it was only 1 for some reason

scaminatrix · Feb 25, 2011

Looks like it has got a parallel port. Not to judge your daughter, but I don't think she'll be able to do this. I've done this before. Can't remember where I got this from, so I can't give credit to the source (been archived for years); but here:

ONLY WORKS ON TOSHIBA'S I ACCEPT NO RESPONSIBILITY BLA BLA But I've tested it, it works fine.

Toshiba Parallel Loopback.

To make a simple device that you connect to your parallell port, a lot of Toshiba computers remove the password when you boot it up.
The device, named "loopback" by some, could be made out of any parallell wire with 25pins connectors (db25).

You should connect these pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, 18-25
~ where pin 1 is top left, 13 top right, 14 bottom left, 25 bottom right.(as shown below with wonderful ascii art!)

What I found:
"
To reset the password on this model, you need to:

* Power off the computer, flip it over, and open the ram door
* Find a small jumper to the left of memory module 0 (the one closest to the board).
* Use a screwdriver to jump this pad while you turn the computer on
* Continue jumping the pad until after the splash screen dissappears
* If successfull the password prompt will go away. If not, try try again.
"

See if that helps?

The laptop is at my house.. no parallel port to speak of.. just a vga port

I do however have a Hirens Boot CD...

See if the app "cmospwd" can help. It's in the "BIOS/CMOS Tools" section of the CD.

Does that help you in any way?

JrRacinFan · Feb 25, 2011

One other thing you could try...

Force yourself in with Windows remote desktop connection. Name of the computer would be Toshiba, make sure you have wifi enabled. While attempting to connect push "alt+F4" on both desktop and laptop at the same time.

LOL JK
Just reporting back that my previous mention will not work and YOU MUST reset cmos.

AsRock · Feb 25, 2011

WOW had same kinda issue with my DELL were resetting the cmos the usual way was not possible.

DELL laptops have gotten crazy now i think no jumper short will work only a password which is only given out by DELL :|. How ever i did find that you can actually pay for a password to get it sorted although that would not work as i got the password of DELL and it failed so they swapped out the mobo to solve it.

Anyways a tech told me what i could do is to remove the battery and cmos battery for over 24 hours but not sure if it works though.

Maybe it work with other brands ?..

Brandenburg · Feb 25, 2011

opened up the ram compartment.. I see nothing that looks like a jumper though

Aceman.au · Feb 25, 2011

Does your daughter even know what the BIOS does? And why would she set a PW?

Have you tried brute forcing the PW? As in guessing till you get it?

Ah, I guess you don't want them in the BIOS mashing keys and ending up smashing the CPU clock up by 2 GHZ and making the main boot priority different ETC

CrAsHnBuRnXp · Feb 25, 2011

Well you could take the laptop apart and take out the cmos battery for about 2 minutes and reassemble.
