Try removing the cmos battery for 30 seconds then replace it. If you open the case you will see a coin cell battery. This is the cmos battery. Removing the battery should reset the bios to factory default settings.

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.
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. IBM Thinkpad laptops lock the hard drive as well as the BIOS when the supervisor password is set. If you reset the BIOS password, but cannot reset the hard drive password, you may not be able to access the drive and it will remain locked, even if you place it in a new laptop. IBM Thinkpads have special jumper switches on the motherboard, and these should be used to reset the system. Also, Hirens Bot CD has Bios password crackers too. Good luck.

If this helps you resolve your problem, please
consider giving a good rating and a quick thanks
or good job.It will help me as well Thank you.

2. Unplug the power cable from the power supply unit.
3. Wait for 30 mins to be safe that your motherboard is fully discharged.
4. Locate the jumper.
5. If there is 3 pin switches, the jumper shows would be in 1-2 position. Just place it in 2-3 position with a few seconds and then return it back to normal position 1-2 position.
6. If there is only 2 pin switch, just remove the jumper with a few seconds and then place it back to normal.
7. Connect all the connection and restart your computer. It it will reset the bios setting.

SOLUTION 5. REMOVING THE CMOS BATTERY

If the jumper switch solution doesn't work, try this solution by removing the cmos battery.

Procedures:

1. Turn off your computer.
2. Remove power source cable.
3. Go to your motherboard and remove cmos battery.
4. Wait for 30 mins or more before returning it back.
5. Place the battery back correctly
6. Plug your power cable and start your computer and it is done.

GOOD LUCK AND I HOPE THIS WILL BE HELPFUL FOR OTHERS.

I want 2 remove password from bios


The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost.

Forgot Toshiba qosimo F15-AV201 cmos password


This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.



B. By Using Software:


I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Is there a backdoor bios password for a Toshiba laptop (model #1805-S253)? A previous employee password-protected the bios but "neglected" to tell us what it is.


The Backdoor passwords are not determined by the laptop manufacturer - the backdoor passwords depend on the manufacturer of the bios itself. Is it an Award biosor an AMI bios etc?
