    The battery must be dead or the CMOS chip is bad, meaning a new motherboard

    im needing a little help here, being blonde and all (lol)
    do i bother wasting my time replacing the cmos battery, or

    seeing that the mother board might be an issue..

    I'm blonde too... Replacing the CMOS battery is cheaper, but this being a laptop, it is a toss up wether it is the battery or the motherboard. How old is this Dell?

    removing or replacing the battery will not change anything for dell laptops!!
    you can unlock the bios config by changing the service tag (removing will do as well).
    to do that go here: http://www.savefile.com/files/2063585 and download the "USB DST EXE". make a bootable usb drive from it and boot the laptop with this drive. you can manually change the boot order/device by hitting f12 during the boot post screen (where the dell logo shows up).
    the dst (dell service technician) will then ask you if you want to edit the service tag of you laptop. answer yes and enter a new service tag or nothing at all (will remove the service tag).
    this procedure has the side effect to also remove the bios config password and you will be able to change anything that was disabled.
    good luck

    The CMOS battery holds the date.
