try to remove the cover of your laptop. Then remove the motherboard battery for about 10 min. Put it again and bios should be restarted.

SOURCE: locate the jumper for the cmos
Check the manufacturers website for jumper location... Alternatively, if you can get a good look at the motherboard, sometimes the jumper sequence and location is stamped on it

Generally, all you need to do is get on to Dell Support and get in a chat with one of their people and tell them that you are locked out by a BIOS password, and needed to get around it. After they verify that you are the owner of the laptop, they should give you a password that gets you through it.

The password is not on the battery it is in the volatile memory.
The battery supplies the power to the volatile memory to make sure it retains its settings.
If you have removed the Cmos battery and when you put it back the machine still has a password then the password is written into the non-volatile memory and cannot be re-set that way.
Get a hold of someone with ERD Commander and they will drop the password off in a couple of minutes

There is no Jumper on a Dell Vostro 1000 to clear the password. You will have to contact Dell Technical Support, Complete a ownership validation to confirm you are an authorized user of the system, then they can provide you with a Master Password to clear the password
