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

Lenovo laptop HDD locked/Sata port 0 locked, insydeh20 bios locked, can't go to boot selection(it brings me to the HDD prompt password again). help!


Sorry, you're hosed. If you forgot your HDD password the only thing you can do is replace the drive and rebuild your S110. There is no way to remove or reset it without using the original password in the original motherboard. Period.
If you're misinterpreting the screen information and it happens to be the bios user password that's forgotten it is possible to have an authorized Lenovo repair center reset it with adequate proof of ownership. Lenovo themselves will not do it. If it's the SVP password for the bios the only solution is to replace the motherboard. Period.

Having passwords that can be reset like in the old days just by jumpering 2 wires defeats the purpose of having a password in the first place.

Remove the biose password lenovo x201


I always recommend popping out the CMOS battery and then putting it back in. This resets all of the settings in the BIOS including the password. In the case of a laptop it can be a bit of work to open it, locate the battery and perform this but it is much less risky than uses the software that is available to crack the BIOS password and then remove it.

This site gives some useful software options for resetting the BIOS password:

Otherwise this is a diagram of the inside of the laptop once you remove the screws from the underside, remove the keyboard and touchpad:

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://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!
