User passwords:
Power on
BIOS execution can be controlled by a Power On Password. This password is set in the BIOS Configuration screen, accessed by pressing the F1 key after pressing the power on switch to turn on the PC. If the person at the keyboard does not know the Power On Password, then BIOS execution halts.

Hard drive
The hard drive is controlled by the Hard Drive Password. After the Power On Password is entered, the person at the keyboard must be able to enter the Hard Drive Password, otherwise the disk drive will not spin up for use. Like the Power On Password, the Hard Drive Password is set in the BIOS configuration screen.

Administrative passwords:
Each of the two user passwords can be controlled by a Master or administrative password. If the administrative password is not set, then anyone who knows the user password can change it in the BIOS configuration screen. If the administration password is set, then it is impossible to reset the user password unless you know the administrative password. The Supervisor Password is the administrative password for the Power On Password. The Master Hard Drive Password controls the Hard Drive Password.

Password Recovery is a feature of Client Security Solution 6.0. This makes it possible for an end user to recover from the problem of "I forgot my Power On Password or Hard Drive Password."

There's a few different options available,
For some bios makers, there's a backdoor password available, the complete list is located here,

Or, you can take out the bios battery.
It's a small, watch battery looking.. battery that will completely reset your bios settings and remove the password.

For that you need to reset factory defaults settings for bios.

Please help me : :' my pc is lenovo g500 and i forgot password bios who help me please


Hi,

I do google your problem and look to the lenovo G500 manual.
here's the manual says.

sources: http://www.lenovo.com/shop/americas/content/user_guides/g410_g510_ug_en.pdf

BIOS password problems I forgot my password. • If you forget your user password, you must ask the system administrator to reset your user password. • If you forget your HDD password, a Lenovo authorized servicer cannot reset your password or recover data from the hard disk. You must take your computer to a Lenovo authorized servicer or a marketing representative to have the hard disk drive replaced. Proof of purchase is required, and a fee will be charged for parts and service. • If you forget your administrator password, a Lenovo authorized servicer cannot reset your password. You must take your computer to a Lenovo authorized servicer or a marketing representative to have the system board replaced. Proof of purchase is required, and a fee will be charged for parts and service.


But in my own way of troubleshooting.
1. open your Lenovo G500
2. Check your motherboard and look for bios/cmos battery.
3. Remove the battery
4. Get flat screw driver then put it between two pins where the cmos battery attached.
5. Hold it for 10 to 15 sec.
6. Put the cmos battery back and the motherboard
7. Power it up and holla the bios setting has been reset to default.

Here the sample image of Lenovo G500 motherboard

How can i off the password at bios settings lenovo corei3 desktop


BIOS passwords can be reset or removed in two ways:

1. using software 2. using hardware.

I would first try resetting or removing using software, here are two software apps to reset or retrieve BIOS passwords.

!BIOS - is a PC BIOS toolkit offering password removal/decrypt and BIOS settings modification/backup/restore.
You can download it here:
http://www.syschat.com/download120.html&act=down

CmosPwd - Cmos password recovery tools
http://majorgeeks.com/CmosPwd_d239.html

You will need to create a bootable Dos, or Linux or NT cd in order to run them.

Good Luck!

There is generally a setting in the BIOS to set what state you want NUM LOCK to be in at boot time. Usually you press F1 or F2 at the Lenovo boot screen to access BIOS.

Dear Sir I forgot bios password in lenovo g430. Computer is start. i want to fomatte pc at that time passowrd is ask i foget it so waht to do.


Disconnect all power sources, including the battery. Open the laptop and remove the CMOS battery (the little round silver thing). Hold the power button to drain any residual charge for 10 seconds. Boot the computer without the CMOS battery inserted. it should say password disabled. Reassemble the computer and you're done!
