You may have to "jump" the cmos to clear the sertings.. passwords are usually written to ROM memory which some will. Keep the data even when not powered by a battery.. close to the battery on the board there should be 3 silver circles. (Like connections that haven't had anything soldered to them). You have to "jump" 2 of them by creating a circuit with something metal like a screwdriver and power the machine on and then off after like 5 seconds. Sometimes there's 3 pins with a jumper on two of them. Then U have to pull the jumper off and connect the middle pin with the pin that wasn't connected before.. cycle the power for 5 seconds. Either one if those ( depending how ur board is designed ) will clear the CMOS ROM and reset all passwords.
I was remove the cmos battry but same password pleas how can i remove the bios password of panasonic cf-t7
SOURCE: bios password
If you remove the CMOS battery for about 30 seconds, replace it, and boot the system. Password should now be gone.
