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.

If you have no password, windows will not work. Seek professional advice with a view to copying your data off before formatting.

Lenovo y410 forgot bios password


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.

Lenovo n500 forgot bios password


Hello, If you forgot your BIOS password,do not worry, you can reset your system back without requesting a BIOS password,Simply unscrew your laptop and get the motherboard of your laptop, locate the CMOS battery on the motherboard and remove for sometime for the battery to discharge say 4-10minutes,or better still if you can locate the jumpers for the BIOS and reset it,the BIOS password will be removed.It is the battery that keeps the BIOS chip alive by suppling it power,if power is not supplied to this chip,then the information on it will be lost. So, remove the battery for some minutes or reset your BIOS jumper on the motherboard WISH YOU THE BEST.

Theres a reset procedure. I believe if you press and hold the F1 key while powering the laptop you should get a reset bios password. Google, reset lenovo bios password.

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.
