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.

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.

To reset the BIOS read the information from this link.

In case of your Lenovo laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

Hi,

I found a homepage with a load of Backdoor passwords, - one of them will bypass you forgotten BIOS password. If you dont know your type, you´ll have to try them all out, or untill you hit the right one:

Good Luck

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.
