pull out the cmos battery as well as the battery, and leave it for 3 minutes. then put the reg. battery back in and boot it up. it should say password disabled. Turn it off and put the cmos battery back in, it should work now. leave positive feedback!
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 battrey, 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 battrey & restart the computer. This will take care of the issue.
If it is a desktop open the computer and you will be able to see the CMOS battery, please 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 battrey & restart the computer. This will take care of the issue.
turn it on and shine a torch onto the screen while it is black. if you can see what is on the screen while doing this you will need to get a new backlight. these are not expensive, around £15. you will need a technician to install it for you though.
ok on all desktops there is a jumper on the motherboard conecting 2 out of three pins and on the motherboard it says psswd. power off and unplug it then remove the door on the back where the ram goes ill bet thats where ull find it. take the jumper off and put it on the other pins. boot it up and password should be dissabled go int bios and make sure. u can leave it like this or turn off and replace the jumper. hope this helps.
P.S. if the jumper isnot by the ram check behind any other doors the laptop might have
