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!

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

When the laptop starts up is asks for a password but i have forgot the password?? how do i access my computer??


You find the original sales-receipt, to prove to Lenovo that you, not a thief, is in possession of your computer.
Then, you telephone Lenovo, and ask for Technical Support on how to unset/bypass the BIOS-password.

Laptop locked


A Windows log on password is removable. Just google it for a software solution. A BIOS [power on password] is not removable. You will have to contact Lenovo support with proof of ownership for help.

Reset factory password on t61 lenovo


password for what? bios or windows?
if it's the windows password, press the f8 key before windows starts and choose safe mode, choose administrator for the username and then go to user accounts and remove the password for your account.
if it's the bios password, you have to strip the laptop and pull the bios battery on the system...it looks like a large watch battery but becarefull not to break anything.

Sorry, there isn't a way to get past the password other than to contact Lenovo. Resetting the CMOS will do nothing. They will ask for proof of ownership before they do anything. I believe they have a "backdoor" password.
