Computer will not boot it is asking for bios password

Unfortunately this is not an easy thing to remove. Try and remember what the password is that you set, you can try your Windows login password if you can't remember what you set it to.

According to a possible way of bypassing it is to hold down the left shift key while you start up the computer. Another may be to hold down 0 and try and enter recovery mode. These methods are unlikely to work but try them anyway, you may get lucky.

If you have some skill in dis-assembly you can open up the laptop and remove the CMOS battery. Then make sure the main battery and power are disconnected and leave it for a week or so. Modern laptops sometimes store bios settings in flash memory so there may not be a battery to remove.

If the first two methods did not work for you, your only remaining action would be to send it to Toshiba to get removed, this will likely cost quite a bit for them to do for you unfortunately.

Sorry if I couldn't help more. Thank you for using FixYa!

How do i remove a built-in HDD password?

If it is the password that has been firmware locked, you cannot. This is to stop people who steal laptops from accessing data
If its a BIOS password, access the bios by pressing ( I THINK) F2 or F1 or Del at start up, navigate through the BIOS screens until you find SET Password and remove it

Toshiba Satalite M35 x, trying to clear bios password, i never set it! Plus the keys are locked, password field will not accept anything

I copied this info from a website since it needs a very particular solution. The only time I had to use it, it worked.
Go to setup (if it lets you) and check the BIOS brand and version.
(If you cant do anything due to the password, then you need some hardware to do that). I hope this helps

You must know the memory address where the BIOS password is stored, and the format in which the BIOS password is stored. Or, you must have a program that knows these things.
You can write your own program to read the BIOS password from the CMOS memory on a PC by writing the address of the byte of CMOS memory that you wish to read in port 0x370, and then reading the contents of port 0x371.

I have a dell latitude laptop and I can't change the boot order as it is locked with an admin password. I looked for the bios battery in the manual to remove and put back but there doesn't deem to be one....

Locate the BIOS clear / password jumper or dipswitch and change its position. Once this jumper has been changed, turn on the computer and the password should be cleared. Once cleared, turn the computer off and return the jumper or dipswitch to its original position.

If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.

Another way to try is use the BIOS mfg "backdoor" password to see if you can get in. It's a little more risky as if you're wrong three times, it may lock you out.
Here's a list of backdoor passwords for many of the BIOS manufacturers... scroll down page 1/2 way to see start of listing...
