How to Remove BIOS Password!
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.
IMPORTANT NOTES:
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.

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 .

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!
