Re: Dell Bios issue
With dell, they put on a proprietary password on all of there machines to lock out the user from making any changes to the dell machine such as start-up/devices and the like.
to clear the bios properly, open the laptop. Look for a battery that you'd find in a watch or old electronic roledex. Remove it and wait a couple minutes(max of 5) then press the battery back into the slot.
As for the jumpers, I am not entirely clear if your motherboard has them. Removing the battery will reset your CMOS and clear the administrator password associated with the bios.
Precautions, before you do. Work in a low humidity environment. If you can help it, try a tile floor with a lamanent desk to open the laptop. Make sure the laptop has no power going into it via the adapter or BATTERY. If you do, you can receive a shock and void your warranty.
You don't have to worry about the power in the laptop after you remove the main laptop battery. Keep those precaustions in mind and you'll be good to go.
