Re: BIOS problem with password
Sometimes removing the CMOS battery will do it but more often it requires moving a jumper from one position to another and back again or shorting two specific soldered on terminals on the motherboard together.
You'll need to know the specific motherboard model number so that you can reference its documentation and find out how to reset the BIOS password.
If you don't know the specific model number there are a couple of utilties I'll recommend that you can use to identify it.
The 1st is Belarc Advisor. This is a PC Audit utility that does a very nice job of auditing your computer's hardware and software.
The 2nd is a little utility that's been around for ages called CPU-Z. It doesn't audit software but it does audit your hardware including your motherboard.
Both of these utilities are Windows versions (they must be run from w/in Windows). If you need a boot utility to audit your hardware, please, post back here and let us know.
Both of these utilities are free and very handy to keep around in you "toolbox".
Please, go HERE for Belarc Advisor
Please, go HERE for CPU-Z

The simplest way to remove BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware. If that doesn't work,you'll need a bios/cmos password recovery tool from http://www.biospasswordrecovery.com
THERE IS A BATTERY ON THE MOTHER BOARD . TAKE THE BATTERY OUT AND POWER ON THE MB FOR A MOMENT. DISCONNECT THE POWER SUPPLY AND INSERT THE BATTERY BACK. BOOT YOUR SYSTEM. THIS SHOULD HAVE SOLVED THE PROB. YOU NEED TO SET THE DATE AND TIME INCLUDING THE DESIRED BIOS SETTING. REGARDS.

the bios settings we do is stored on CMOS battry so remove the CMOS battry and insert it again the earlier settings made to bios will be earesed and default settings will be loded this will remove the bios password even
How to remove and unlock hard drive password? Is there any software to recover hard drive disk password? Where to download hard drive password cracker? Is it possible to reset the hard drive password?
According to Lenovo and many other manufacturers' website, if you forget your hard drive or hard disk password, there is no possible way to reset your password or recover data in the hard disk drive. Basically the hard drive is unusable. Scary right? However, this is often not true.
Most people are not aware that most hard disk drives have the ability to set a hardware password, just like the Bios password for motherboards, thus making the drive completely inaccessible unless a correct password is provided during the BIOS POST test. Usually these features can only be found in laptops, this is when you set a password on your notebook, the hard drive together with the motherboard becomes locked.
Most experts would say if you forget the original HDD or Bios password, there is no way of restoring it by generic system tools. Unlike the Bios password where there is a master key or with the removal of the bios battery, the password is erased from the flash memory thus the settings is restored to factory settings without the password, however, this does not applies to hard disk.
For that you need to reset factory defaults settings for bios. For reset bios u have to open back side of your laptop then u find motherbord circuit there. pull cmos cell on motherbord for 15 minute then it reset to defaults. Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear" It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset. then again set it in 1-2 its original position.
remove the cover which has your power button and covers the LCD cables. Remove the keyboard and flip it over, being careful to not pull too hard on the cable. There's 2 small triangular silver connection pads beside the keyboard connector on the main board - connect them together and power on your computer (flat screwdriver works fine). Press the f2 key - you'll find it doesn't prompt you for a password. You can lift off the connections now. Go to exit and save changes, and you're password free.
