I was trying to help out a friend of mine a little while ago with a laptop that her son left to her. I cant remember the model, but I do remember it was a dell. Anyways, the laptop had a bios password on it and she is no longer in contact with her son, so she could not get the password. I know that on a PC that there are ways to reset the password by removing the battery or by the jumpers, but I have never found a solution to reseting a bios password on a laptop. I even went as far as to breaking down the laptop and actually desoldering the cmos battery and leaving it out for several minutes, but when I soldered the battery back in and reconstructed the laptop it still asked me for a password and will not even attempt to access the hard drive until I provide that password.
I no longer have the laptop in my possession because I gave it back to her, but I don't like to fail on projects like this and it has been bothering me ever since. So, I was wondering for my own knowledge if anyone knew any way to get past it.
Also, I did say bios password but I wasn't totally sure if it was because the password was to access the hard drive, not the bios.
