    The board is a TekRam P5T30-B4E. While I have removed the battery and unplugged the power cord to the power supply from the outlet (which I know will clear this on most boards) this one password or passcode) seems to be unusually stubborn to clear. I know on most older DELL machines there was a seperate jumper for the password and am wondering if this is the case here?
    Also, does anyone know where I can get a manual for this board?

    Thanks,
    Phoenix

    Who is the manufacturer of your motherboard and which BIOS does it use? I should be able to find a backdoor for the BIOS.

Some motherboard passwords can be cleared by unplugging it from all power supply connections and taking out the motherboard battery, the one that looks like an oversized watch battery, if it has one. Another way is to throughly check the board for jumpers that may be labeled "passwd" "bios config" or similar. Remember when playing with jumpers to not change anything you don't understand and to put everything back when you are done.

How to remove unknown bios password?


All laptops and desktops carry a bios battery, the easiest way to reset your bios is open it and umplug the battery for at least 5 minutes and plug it back. You will have to open the laptop. Usually is a battery connected near the CPU its like a watch battery. But if its a 5 year old laptop the most easiest way y to unpkug from all power sources and leaving it alone for at least a day press the power button so it can release the stored power on the capacitors.

I can't find a decent manual for your computer but there will be 2 pins on the motherboard that will say BIOS Clear. Short these 2 pins and turn the computer on. This is the only way to bypass the BIOS password. This operation will clear the BIOS and reset to factory defaults. After the BIOS is cleared, turn the computer off and take off the short.

Unknown pass word


When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there also
The most common way that we 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 cmos the battery power, the BIOS/CMOS settings will be erased:. Hope this helps
