Hi,
Are you the one who set up the BIOS password? If not, unfortunately, there's no way for us to retrieved the password. The only way you can reset the password to default settings is to reseat the CMOS battery on the motherboard, its a circular thing that looks like a battery of a watch,sometimes a pin hold it, just detached it then wait for at least 30 minutes then connect it back again,
Note: Before you reseat the CMOS battery,make sure that everything is unplugged on the computer, like AC adapter,battery and all external devices...
Hope this will help...Your response is very much appreciated...

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

I forget my lenovo 3000 y500 bios password, how do i bios open without open the cmos


Normally, you can just move a jumper or unplug the CMOS battery to clear the password. But, I found the following in the Ideapad Y500 repair manual:

"A supervisor password (SVP) protects the system information stored in the BIOS Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the servicer, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee."

Forgot password on my lenovo flex. how do I reset?


You may be able to reset or cancel the password by going into the BIOS setup screen and disabling passwords there. Usually, you get into the BIOS by pressing the F2 key repeatedly a second or two after you turn the power on. Failing that, the laptop has a disc-shaped battery about the size of a quarter somewhere under the bottom panel. It's called a CMOS battery. Removing that battery for about twenty seconds then reinserting it usually returns all settings to "factory default" which means no password! Good luck.

Lenovo T61 Power-on password. Hi, my Lap suddenly asks me a code that I unknow. It doesn't able access to any setup, even when I press F1 to open BIOS Setup Utility to remove. I removed Backup battery...


The BIOS password isconfigured from the BIOS setup and this password is stored on an 24RF08 EEPROM chip. There is no backdoor passwordavailable and IBM/Lenevo support says the motherboard needs to be replaced.Also removing the BIOS battery to discharge the BIOS and reset it to thedefault settings will not allow you to bypass this password. This also applies to thePower On Password and the Hard Disk Password.There is a way to crack thepassword but you need electronic skills, electronic components and severalprograms plus a working computer to carry out this task.For details on how to dothis check this WEB site.http://sodoityourself.com/hacking-ibm-thinkpad-bios-password/http://www.fixya.com/support/r4335050-remove_bios_power_password_thinkpad

Can not get into phoenixbios setup utility


Hi

Is it like when you turn on your computer it asks you for a BIOS password.


You need to open the notebook from the back and locate the small battery which looks like the shape of coin,
After locating it take that battery out and turn on your computer,
Once your computer is fully loaded then turn if Off,
Then put the battery back and turn on your computer
Try to go into BIOS.
I am sure you will be able to go into BIOS.
