How do you get the bios password ?


Well, a BIOS password can be removed by either clearing the CMOS jumper or removing the CMOS battery on the motherboard.

On a regular computer this isn't too difficult, but unless you have taken apart your laptop before or are willing to try it, I would take it to someone you trust to work on your computer. Clearing the CMOS of a laptop generally requires near complete disassembly.

Cant log into laptop with my amidd password


if you are getting prompt, "This computer <Service tag number>-595B is password protected ..... you'll need to call Dell technical support to get the master password generated to clear the message. There is no hardware way to clear the password short of replacing the motherboard. Same applies for a BIOS level Hard Drive Password.

Cannot clear bios password


Hi, you won't be able to, Dell has put it there to stop people from messing with the bios.
You can phone Dell and they may tell you the password, but you will have to go through some security check to prove that the laptop is yours.

If you know how to take your laptop apart ( not recommended ) you can follw this guide :-
http://support.dell.com/support/edocs/systems/latc610/sm_en/rsrvbatt.htm#1000202

Disconnecting the battery for a few minutes should clear the bios and return to default settings.

Let me know if this has helped you.

For this issue I have had myself. First and foremost the best solution is to flash the notebook, clear EVERYTHING out, most tech. support locations are able to this, with no problem, OR you may also try, f you can get into the BIOS, there should be an option to "Load Defaults". Choose that and then "Save and Exit". If you cannot get into the BIOS because you do not know the password, look for a jumper on the motherboard marked "Pass", "PWD", "BIOS", etc. Typically you should move the jumper over one pin, or it may have just two pins, and they need a shorting jumper on them. Do that for a few seconds, and replace it as you found it. That should clear the password, and perhaps all other non-default settings, as well.
Let me know how it goes,
Thanks,
Justin...

Bios password


if you know the password, then when you go to change it instead of entering a new password just press enter on the keyboard. If you don't know the password try, admin or administration or even the word password.
