How to Remove BIOS Password!

When you set a password for your BIOS and forget it, what should you do!.

OK, there is some methods to clean BIOS password, I'll show you follow me & read carefully.
The computer motherboard there is a piece called (BIOS /  CMOS ) contain information stored where the default settings for the BIOS manufacturer,and you as a user of the device or an engineer or technician want to edit some of the available settings on the BIOS (such as a password when log into the BIOS, change the date and time, boot priority  from hard disk or CD, eliminate the use of certain ports such as USB port - LAN - printer port... etc) these adjustments saved in the "CMOS" and retains them even if electricity cable has been removed, but these settings disappear in 3 cases:

1 - Removing CMOS battery from Motherboard for a period of 15 to 30 minutes.

2 - The end of battery life, it has the number (CR2032) you'll find it in hardware stores or in watchmaker.

3 - Using "Jumper" to clear CMOS modifications in specific position.

When we want to disconnect the CMOS battery and remove it from motherboard or we want to deal with  motherboard  in general you should do the following:

1 -  Unplug the power cable from the computer ( from the back of the device permanently).

2 -  Unplug the screen cable which is connected with the computer (because it delivers some shipments through the screen cable to motherboard ).

3 -  Separate any cable may be plugged into the device by electricity (such as printer - scanner ... etc).

4 - before you open the compute touch any external metal object  ((non-computer)) to discharge static charge from your body because it may cause damage to some pieces of the device.

5 - It's strongly recommended that you wear a rubber gloves to make sure you don't transfer any shipment to device parts.

Method n°=1 ( removing the CMOS battery )

removing CMOS battery
1 -Open the computer case, then look at the motherboard you 'll find the CMOS battery with the number  ( CR2032 ).

2 - Now remove the battery & leave it outside the motherboard  for 15 - 30 minutes (and the device is disconnected from all power cables).

3 -put the battery back into the motherboard and turn-on the computer, you 'll have no BIOS password!.

Method n°=2 ( using jumper )

a jumper is a short length of conductor used to close a break in, or bypass part of, an electrical circuit.

1 -find the jumper on the motherboard, it's labeled as CLEAR, , JCMOS1, CLR, CLRPWD, PASSWD,CLEAR CMOS, PASSWORD,PWD,PSWD .

2 -remove it from the two pins its currently on so that it covers the pin that isn't covered. exp: in the picture pins 1 & 2 are covered, you need to remove the jumper and put it on pins 2 & 3.

3 - when you do that turn-on the computer, you'll find that the BIOS password was cleaned.

4 - now turn-off the computer and switch the jumper to the original position.

Method n°=3 ( using software )

like "PC CMOS Cleaner", but the boot priority must be from the CD in advance!, remember you don't have the password so you can't edit BIOS settings.

1 - Download the software "PC CMOS Cleaner 2.0" (official) for free.

PC CMOS Cleaner 2.0
2 - it's an ISO image, you need to burn it in CD or DVD, you can use "free ISO burner"

3 - put the CD/DVD in the drive and reboot your computer, then press any key to boot from the CD/DVD drive.

4 - the software 'll be opened, step1: try possible password for your BIOS ( you need to write them in a paper ), if it does't  work click on Next for step2.

5- step 2: rest the BIOS to default status
choose "choice 1" first ( to keep date and time), if it does't work try "choice 2" , the BIOS password 'll be erased.

that was the 3 popular ways to remove BIOS password, if you need any help or question i'm here,just leave a comment!
