Welcome to Fixya
Common procedure in resetting the password is by resetting the motherboard by reseating the CMOS battery. You need to access you motherbard and locate the circular silver metallic object on the motherboard. This is much bigger in size compared to a wristwatch battery. CAREFULLY remove the CMOS battery, avoid touching it with your fingers, and leave it out for about 120 seconds
. This will flush the CMOS memory which stores the BIOS password and all other configuration. Put the the battery back in and turn on the computer.
Other procedure is the jumper reset. Some, but not all, motherboard manufacturers provide a set of three jumpers on their motherboards that provide you with the ability to clear the Bios/CMOS settings, thereby allowing them to be reset. For the most part this is used when the Bios/CMOS data becomes scrambled and you need to clear the Bios/CMOS in order to return the computer to a functional state. This same procedure, however, can be used to clear passwords from the Bios/CMOS setup. Typically a jumper will be found across pins #1 and #2 as the default position, and by shutting the computer down, unplugging the power cord and then moving the jumper so that it is across pins #2 and #3 will clear the Bios/CMOS settings.
If procedures above has been done and yet you are getting same results. Its time to call you manufacturer and have the motherboard re-flushed or re-imaged.
