Bios password

I'm not sure if this key will remove the BIOS password on the M105 since that model uses a thumbprint scanner and stores the BIOS password in an EPROM chip instead of in the CMOS, but it's worth a try since the other alternative is to take the laptop to a Toshiba repair shop to have the password removed.
 
I believe you can clear a BIOS password stored on an EPROM chip by removing the CMOS battery on your mobo while all power is off and unplugged from your computer.
 
Reaching the laptop's main board bios battery isn't as easy as removing the battery on a regular motherboard. Often the retaining bracket for the battery is soldered down.

Sorry to be the bearer of bad tidings, but removing the BIOS Battery will not clear a password stored on an EPROM, EEPROM or any variants of these. They are Non-Volitile memory. In other words they do not need any power to retain the data stored on them. The raw chip can be stored disconnected for years and still have the same data. If it has a TPM it could be more difficult than a E(E)PROM... Contact Toshiba they should be able to provide you with " Backdoor Password " if you provide them with proof of ownership. I know that Dell does this.

i had this problem with my PC and i took the CMOS(watch battery) out for 10 seconds and replaced it and the password was gone! this one will work...finding it on the laptop might be a hassle
 
For years, laptops have been deliberately designed to prevent user neutralization of the BIOS password. In most brands, PC techniques such as removing CMOS bettery, etc., will not work. The purpose is to deter rampant thievery of laptops, especially in airports. The fix is in many cases to send it in to the factory.
 
You are likely looking at the drive being locked at the hardware level. Best is to have a known good local computer shop look at this first to confirm whether it's locked at the hardware level. If it is, you will need the pros to unlock the unit. Another thing you can try is to swap out the hard drive and put in a new one if the data on the locked drive is not that important. However, the system might be still locked from any change, but you should be able to do a new install with a new hard drive.
 
Windows password, bios password and hard drive password are usually all separate items on modern laptops.

The windows password is fixable with a boot CD, but the others have become harder to change the newer it is.
