THis may or may not work.
First you must reset the bios. To do this you must short the J1 jumper an start the computer. After the start then stop the system, remove the jumper. It should ( but may not clear the bios). Hope this helps you. Good Luck!i  lost my lenovog510 - mb350sl_1.jpg

Need the bios password on my gateway solo 9500


When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS using the arrow keys scroll down to set user password or supervisor password you can change or remove your password from there

also

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself.

Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.

cmos battery Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment. Although on some motherboards the Cmos battery is soldered in

Often many users will leave the administrator account alone or have other accounts with administrator rights. If you're not logging into the computer as administrator or have other accounts follow the below steps to reset your other accounts password.

Reboot the computer into Safe Mode


When logging into Safe Mode you should be prompted with an option to what account you wish to use. Select the Administrator account. If prompted for a password try pressing Enter on the keyboard for no password. If this does not work, try other passwords you may have used. If you're unable to log into the Administrator account skip to the next suggestion.


Once you've logged into the Administrator account open Control Panel and User Accounts.

I can't remember my password??


If you have forgot the BIOS password of your desktop computer, then you need a simple way to change your BIOS password. Its not that difficult because you just need a simple trick to reset your BIOS password.

* Shutdown your desktop computer and switch off the power to the CPU
* Open your CPU cabinet
* Find a circular, (mostly) silver metallic object on the motherboard. This is the CMOS battery
* Carefully remove the CMOS battery and leave it out for about 120 seconds. This will flush the CMOS memory which stores the BIOS password and all other configuration.

* Set the battery back into place and power on the computer.
* The computer should then warn you that the CMOS configuration could not be found. You can either reconfigure it yourself or restore defaults. Restoring the default configuration should be fine.
* You will notice that the BIOS password has been cleared and you can boot without it.

Note : Once you remove your battery from the mother board, you will find that all your time settings in your computer would be lost, and some softwares may stop working which are based on your computer time.

Good Luck...

I have lost the bios password... any body help me to recover without opening case


This is a tricky one because the BIOS password is made to be the hardest password on a computer to break. Some manufacturers allow you to enter BIOS without the BIOS password but most do not. Here are some troubleshooting methods starting with the easiest and moving on to the hardest.

To enter BIOS hit the F2 key repeatedly as the computer boots up. You should enter BIOS after the first loading screen. If this does not send you into BIOS, try the ESC, DEL, and F1 keys. Once in BIOS find where you can set the password and reset it or enter a blank password as your new password.

If you can't access BIOS or are prompted for a password once you enter BIOS, try the following methods to flush the BIOS password cache:
1. Contact your manufacturer's support and ask if they have a backdoor BIOS password that they will allow you to use. This works to allow you to enter that password instead of your own and easily fixes the whole problem, but not all companies will tell you their password. You can also do a google search for your manufacturer's backdoor BIOS password since many of them have been discovered.
2. Send your laptop to your manufacturer to have them reset the password manually, although this takes an undisclosed amount of time and they will often make you pay a fee if you are not under warranty.
3. If you don't want to pay your manufacturer, open your laptop and locate the motherboard. On the motherboard there is a CMOS battery, if you don't know where this is use your PC manual. Remove the CMOS battery for an hour and then place it back on the motherboard. This should reset the password. After this turn on your computer and enter BIOS. This will reset all your BIOS settings so it may take a few minutes to open. After it is open, just exit BIOS and everything should be working properly. Just be very careful when opening the laptop and handling the CMOS battery because you can severely damage your laptop if you don't handle it properly.

Hi dear friend i have notebook acer 4315,i lost password setup and i cant work with computer ,becuase i cant enter to system,i would like how to reset bios password.plz help me its urgent best regards


Hi,

If you have forgot BIOS password then you have to reset CMOS jumper setting. Please follow the below steps: Open the Laptop back panel. Locate the CMOS battery, remove it & then with the help of a screw driver keep on pressing the terminal inside it and turn ON the computer for 10 secs and Turn Off (make sure you keep on pressing the terminal with a screwdriver while turning ON). It will short the BIOS setting. Now, fix the CMOS battery & restart the computer. This will take care of the issue.

Thanks and regards,
Jitha
