How do i solve the BIOS password?

(1) Procedure crack method:

This method is available for access to the operating system but does not enter the BIOS setup (requires a password). To do this: switch the computer to DOS, and then enter the following cracking program after the prompt "c:windows〉":

Debug

-O 70 10

-O FF

-Q

Then use the Exit command to exit DOS, the password is cracked. Because the BIOS version is different, and sometimes this program can not be cracked, you can use another similar program to crack:

Debug

-O 71 20

-O 70 21

-Q

Exit DOS with the exit command, reboot and hold down the DEL key to enter the BIOS, you will find no password to block your way!

(2) Discharge method:

When "BIOS setup" and "operating system" can not be entered, you can not switch to the DOS mode to use the program to crack the password. At this time, only the use of discharge method. There are two kinds of discharge methods: one is "jumper discharge method"?? Open the Host box, on the motherboard to find a COMs-related jumper (refer to the motherboard manual), this jumper is usually inserted in 1-2 of the pins, as long as it is inserted in 2-3 of the pin, and then put back 1-2 pins to clear the password. The other is "COMs battery discharge method"?? Open the mainframe box, on the motherboard to find a button-type battery, called CMOS battery (for the bios of the individual power supply, to ensure that the BIOS settings are not due to computer power loss), remove the COMs battery, wait 5 minutes to put back the battery, the password can be lifted. However, the BIOS password no matter how set, with a universal password can enter the BIOS setup and operating system. Of course, the password you set yourself can also be used. Other settings in the BIOS will revert to their original state, which requires a reset to optimize computer performance or resolve hardware conflicts.
