You can remove your BIOS battery for about 10 seconds and the BIOS password and adjustmens that you custom made in your BIOS will reset.

you dont need to jump cmos if you get out the BIOS battery for a couple of seconds because the BIOS will reset itsself

let me know how it worked out
greetings

I dont remember the supervisor password now Im locked out of the bios on my laptop and it sucks.


Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself.

Try this first : 
manufacturer name : Toshiba 
password : Toshiba

Most Toshiba laptops and some desktop systems will bypass the BIOS password if the left shift key is held down during boot

Method 1 : Removing the CMOS Battery

The CMOS settings on most systems are buffered by a small battery that is attached to the motherboard. (It looks like a small watch battery). If you unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank. (Along with any other machine specific settings, so be sure you are familiar with manually reconfiguring the BIOS settings before you do this.) Some manufacturers backup the power to the CMOS chipset by using a capacitor, so if your first attempt fails, leave the battery out (with the system unplugged) for at least 24 hours. Some batteries are actually soldered onto the motherboard making this task more difficult. Unsoldering the battery incorrectly may damage your motherboard and other components, so please don't attempt this if you are inexperienced. Another option may be to remove the CMOS chip from the motherboard for a period of time.
Note: Removing the battery to reset the CMOS will not work for all PC's, and almost all of the newer laptops store their BIOS passwords in a manner which does not require continuous power, so removing the CMOS battery may not work at all.For eg: IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set.

Method 2 : Using the Motherboard "Clear CMOS" Jumper or Dipswitch settings

Many motherboards feature a set of jumpers or dipswitches that will clear the CMOS and wipe all of the custom settings including BIOS passwords. The locations of these jumpers / dipswitches will vary depending on the motherboard manufacturer and ideally you should always refer to the motherboard or computer manufacturers documentation. If the documentation is unavailable, the jumpers/dipswitches can sometimes be found along the edge of the motherboard, next to the CMOS battery, or near the processor. Some manufacturers may label the jumper / dipswitch CLEAR - CLEAR CMOS - CLR - CLRPWD - PASSWD - PASSWORD - PWD. On laptop computers, the dipswitches are usually found under the keyboard or within a compartment at the bottom of the laptop.
Please remember to unplug your PC and use a grounding strip before reaching into your PC and touching the motherboard. Once you locate and rest the jumper switches, turn the computer on and check if the password has been cleared. If it has, turn the computer off and return the jumpers or dipswitches to its original position.

Method 3 : 
Jumping the Solder Beads on the CMOS

It is also possible to reset the CMOS by connecting or "jumping" specific solder beads on the chipset. There are too many chipsets to do a breakdown of which points to jump on individual chipsets, and the location of these solder beads can vary by manufacturer, so please check your computer and motherboard documentation for details. This technique is not recommended for the inexperienced and should be only be used as a "last ditch" effort.

Method 4 : 
Password cracking software

The following software can be used to either crack or reset the BIOS on many chipsets. If your PC is locked with a BIOS administrator password that will not allow access to the floppy drive, these utilities may not work. Also, since these utilities do not come from the manufacturer, use them cautiously and at your own risk.

How do you reset a Toshiba Satellite L305D Power on Password?


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.
  • When successful, make haste to update your bios: http://cdgenp01.csd.toshiba.com/cont...s/slb8v140.exe Toshiba's have a nasty habit of setting bios passwords on their own. I'm assuming thats why you're here.

Bios password


The master password for Compaq is "compaq"
If that doesn't work you need to use a jumpe on the motherboard:
This Jumper is often named like: "RTC_CLEAR" , "CLEAR CMOS" , "CLRCMOS" , "CLRCMS". His position is often near by the motherboard battery. You will need to reconfigure any BIOS changes that you have done.
