Tip & How-To about Computers & Internet
Let's get to it!
There are two ways to reset your BIOS/CMOS, the first way is to locate the three pins that relate to the BIOS/CMOS clear header. If the jumper is over pins 1 and 2 it represents normal operation. Therefore to clear the BIOS/CMOS one would place the jumper over pins 2 and 3 for about 15 seconds.
Now remember that the BIOS chip is a EEPROM, this means that it will store information so long as it has suffiecient power, from a power source. In this case it is a silver button cell located on the mainboard, usually of size CR2032 3Volts. Once the jumper is placed over pins 2 and 3 for about 15 seconds, quickly place the jumper back to the normal position, which is over pins 1 and 2.
The second way to clear the BIOS/CMOS is to simply remove the BIOS/CMOS silver button cell, for about a minute and then reinstall it in the correct orientation.
Well thats it, now you will be able to boot your system on the defalts settings. Remember to enter the BIOS/CMOS by hitting the approprite key during Power On Self Test. There are many different keys, depends on your computer system. Common ones are Delete another is F12.
Enter the BIOS/CMOS to correct the date and time and to set the boot priority.

All the best!

Use this jumper to clear the CMOS values (e.g. date information and BIOS configurations) and
reset the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the
two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two
pins for a few seconds.
• Always turn off your computer and unplug the power cord from the power outlet before
clearing the CMOS values.
• After clearing the CMOS values and before turning on your computer, be sure to remove
the jumper cap from the jumper. Failure to do so may cause damage to the motherboard.
• After system restart, go to BIOS Setup to load factory defaults (select Load Optimized
Defaults) or manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for
BIOS configurations).
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper
The most common way that most of us 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 a 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 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.
