In his line of work, Instructables user [Harrymatic] sees a lot of Toshiba laptops come across his desk, some of which are protected with a BIOS password. Typically, in order to make it past the BIOS lockout and get access to the computer, he would have to open the laptop case and short the CMOS reset pins or pull the CMOS battery. The process is quite tedious, so he prefers to use a simpler method,.

I don't believe that this is possible outside of a Toshiba workshop. Toshiba ASP Support may give you the Response Code for free (with enough explanations on your side).

The plug itself is pretty easy to build. After soldering a handful of wires to the back of a standard male D-sub 25 connector in the arrangement shown in his tutorial, he was good to go. When a laptop is powered on with the plug inserted, the BIOS password is cleared, and the computer can be used as normal. It should be said that he is only positive that this works with the specific Toshiba laptop models he lists in his writeup. It would be interesting to see this tried with other laptop brands to see if they respond in the same way.
Since no laptops are manufactured with parallel ports these days, do you have some tips or tricks for recovering laptop BIOS passwords? Be sure to share them with us in the comments. Posted in, Tagged,,, Post navigation.
Used to work, about 6 years ago:)). Nowadays most bios pw (challenge/ response ) are insanely easy to remove via keygen or failing that some hw method, eeprom on the board itself most time i only need bios to boot from cd/dvd and re-install, usually on encrypted boot in which case sometimes it’s easier to take the hdd out, ofc it will fall to 2nd,3rd boot option (cd/dvd), erase partitions + mbr through linux, put hdd back in, cd in then restart it will fail to boot from hdd and just start up cd, obvious but i’ve seen plenty of people wnot think this.
Toshiba’s from ~2-5 years can randomly get BIOS passwords if the BIOS wasn’t updated. Usually clearing it involves unplugging the AC adapter and battery, opening the memory bay, removing the memory and then jumping a solder pad for about 15-30 seconds. It varies for each series, but J1 open is a pretty common label. You may have to peel back plastic film to get to it too. If you do succeed in removing a random one, make sure you grab the newest BIOS update so it doesn’t happen again.

The microwaves erase the password. I like when the CMOS battery has its own little access panel, but you don’t see that very often nowadays. I haven’t, anyway. BIOS passwords p*ss me off because i can’t even boot from USB without it, if it’s set the annoying way.
Of course, if you really want to protect your data, do that, plus build your computer inside a safe and weld it shut. Or, it’s a safe, just lock it i guess. And bolt it down. And laser tripwires, which text you if tripped, and cameras.
CMOS battery for holding password in memory? Man, this must be a very old laptop (1990s?). As above, they switched to EEPROM in most cases. The EEPROM would usually be a small SOIC8 package that was even silkscreen identifiable as “PWD1” or something similar.
If you were not inclined to dig out an eeprom reader, it was simlpy a case of shorting two pins together and booting up the laptop. This caused the eeprom to erase itself and wipe the password. Had this a few times on DELL machines, you can find exact details on google. Also as posted above, it’s all old hat anyway. Look up the guy “Dogbert”. He has reversed engineered a lot of BIOS and given away password calculation algo’s free. Some bad bad people have even put his free work into commercial products.
