This Toshiba bios password removal process is meant for use on Toshiba laptops that you own or have had permission from the rightful owner to remove the password. If any of these processes are done incorrectly it may result in complete system failure or permanent system damage (you’ve been warned!).
Some Toshiba bios passwords can be reset using the Key Disk.exe utility, to do this you need a 1.44Mb floppy disk. Format the disk using Windows and then with a hex editor, change the first five bytes of the second sector to 4B 45 59 00 00.
Then put the floppy into your machine and boot it up, you’ll be asked for a password, just press Enter. Then when you’re asked to set the password, type Y then Enter, this will get you into the bios configuration where you can then type in a new password.
Aside from the KeyDisk, you can build a parallel Loopback plug, this is a simple device that plugs into the parallel port of the machine and removes the password when you boot it up.
To make it you will need a 25 pin DB25 plug, take the plug apart and join these pins using some old cable;
Pins: 1-5-10, 2-11, 3-17, 4-12, 6-16, 7-13, 8-14, 9-15, and 18-25

Plug it into your parallel port and boot up your machine, the password should be removed as soon as it boots.
Note: This will work on majority of older Toshiba’s (1995 – 2002) and obviously only ones that have a parallel port.

well – after reading a dozen or so random rants on how to reset the bios pwd (that don’t work) it’s refreshing to see the real answers that do work.
Many thanks
To sridhar, jim and serdar, i am sorry for not able to reply an answer, because i just copy paste this from other site. You can check at http://www.laptop-repair.info/toshiba_bios_password.html for more details or update. Thank You.
I wasn’t able to see the CMOS CLR1 referred to above to clear the CMOS for a Toshiba Satellite M50, so eventually resorted to a system teardown (see http://www.irisvista.com/tech/laptops/Toshiba_Satellite_M55/laptop_motherboard_1.htm) and de-soldered the CMOS battery from the motherboard for 24 hours, which worked just fine.
Thank you verry much If functions, that would be super I announces itself if it folded Benjamin

can anyone help me to unlock password, how to try to remove or unlock that password
thank n best regard

I just worked on a coworker’s Toshiba Satellite A105-S2061 with the BIOS & boot password problem. Geek Squad couldn’t fix it and Fry’s told him to send it back to Toshiba and pay to have it cleared. After weeding through the myriad of “solutions”, I settled on looking into the A100 (PSAA2A-02C01N) fix listed here. It’s the only one that made sense. This laptop only had a PAD500 jumper located where it said it was. The instructions are pretty much accurate with the exception of #6. I held the short on through the boot sequence until it booted. It took a few times for it to take (8 – 10), but it did finally do the trick. Here’s what I did:
1. Remove Memory Cover from base of machine
2. Release & remove right side Memory Module – with the memory closer to you.
3. Lift black plastic insulation
4. Open the lid enough to turn the laptop on and set it on its DVD edge – like a book.
5. Locate & short PAD500 Pin 1 & 2 together. I used a “U” shaped piece of wire 6. Power on the laptop while still shorting Pin 1 & 2
7. If you receive the password prompt, turn it off and try again
8. Have patience and keep it up until you clear the password
This does work on this model. I was about to give up until it finally cleared. Do not pay anyone to clear the password if you have this laptop. It is relatively easy. I emailed conradodav@hotmail.com – from this forum – only to receive a reply offering me a guide that “tells me how” for $55! Nut much better than Toshiba’s service fee. Feel free to email me if you have this model – I’ll try to help you through the process I used.

plzzzz How To Clear Your Toshiba Bios Password tecra m2
On the Satellite 1130-S155, there are two tiny copper pads next to one of the memory slots, same side as the mini-pci slot. They are labelled J1 and there is a tiny resistor (?) right next to it. Just short across the two parts of the pad – they are shaped like they would interlock (as opposed to being just two dots). You don’t even need to remove the memory. This removed the bios password for me. Thanks for your guide getting me to the right neighborhood.

I have a Toshiba Tecra M2 laptop (Part PTM20U-0QMUZ8) that comes up with the HDD password and I don’t know how to disable it. This is a system I bought at a yard sale (it was cheap) and I do not know if it is possible to disable the password. Any help would be appreciated.
Hi, I have the same problem with Yasser with Sattelite L300. The problem is when it boot up it will stay on Toshiba Leading Innovation screen with the option to press F2 and F12 but nothing happens when you pressed them. Thanks in advance!.
Hello! Many thanks for this post! I just wanted to report my success with resetting the BIOS on an Equium / Satellite L30-149 laptop. By the way, “Equium” laptops are actually “Satellite” laptops but for some reason Toshiba names them “Equium” in some european countries. Anyways, on this laptop there was a JP1under the Wi Fi cover just like it was mentioned in the instructions above for the Satellite L10. I used a small flat headed screw driver to short it. But in my case, I had to short JP1 for 20 seconds. Also, I had the laptop unplugged and its battery removed. Again, many thanks for helping me reset the password on this old laptop!
