Need to locate the jumpers on the motherboard of dell latitude d420 notebook to reset os password


I'm not sure the d420 has a jumper for BIOS reset on the motherboard. I think you will need to remove the small CMOS battery under the keyboard (for around 15 minutes) to reset the BIOS password and settings.

Hi I have a D420 its a small one thats what i like about it i also have a d620 but i wanted to upgrade my d420 with something to make it a little faster like a processor upgrade ...? im not sure about the...


Hi,

Your thoughts are breaking up as you are typing.

You stated;
1) I have a Dell Latitude D420 and a Latitude D620.
The D420 is small, that's what I like about it.

I want to make my D420 faster, is there a possible Processor upgrade?
I'm not sure about the specifications of the motherboard, so I do not know if this is possible.

I know I can get an SSD Harddrive,............the rest is illegible to me.

A) The D420 keeps going slow.

Question: After what?
After you installed an SSD harddrive? After you flashed the BIOS?


B) Was fast when I flashed it.

Question: Flashed the BIOS?
Why?
Why do people always rush to try to upgrade their BIOS program with a flash, when they do not know if it will help, or not?
One mistake and you have a dead laptop. Use it for a paperweight.

When you upgrade the BIOS you have the option to save the original, so you can go back to it in case there is trouble.
Did you?

Post back in a Comment.


While I wait.
To upgrade to a better Processor you need to know;

1) What Processor socket is on the motherboard

2) What is the motherboard chipset, and specifically, what is the Northbridge chip of the motherboard chipset.


To explain;

The motherboard chipset is the Northbridge chip, and the Southbridge chip.

(For the Dell Latitude D420 motherboard. This does not apply to motherboards that support the Intel Core i3, i5, i7, or i9 processors)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

{Note*
CPU = Central Processing Unit. Another term is Microprocessor, or simply Processor for short. Does Not mean Personal Computer}

Chip and Chipset are slang terms for I.C.
Integrated Circuit.

http://en.wikipedia.org/wiki/Integrated_Circuit

The Northbridge chip is so aptly name because for one, it sits on the motherboard to the North, or top of the motherboard. Generally right under the Processor socket.

The Northbridge chip handle the Processor, Ram Memory, and High speed graphics.

{High speed graphics being AGP, or PCI Express. Not a graphics card installed into a PCI slot, nor Integrated Graphics. {Integrated Graphics, OnBoard graphics, same/same}


The motherboard chipset is an Intel 945GMS,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core.2FCore_2_Mobile_Chipsets

(Part number printed on the Northbridge chip is Intel 82945GMS. Part number on the Southbridge chip is Intel 82801GBM)

The Northbridge chip supports Processors with up to a 667Megahertz Front Side Bus. (667MHz FSB)

Will support Processors with either a 533MHz FSB, or a 667MHz FSB.
667MHz FSB being the maximum it will support.

The processor socket is a Socket M.

I just bought a used dell latitude d420 and its locked and the person forgot the password how do i unlock it


I am afraid that such kind off issues could only be solved by motherboard replacement, unless you can contact your laptop's manufacturer support with a proof of ownership of this notebook.

There is also this service which can help you crack the BIOS password:

Did you contact DELL. As long as you have the police report, they should be allowed to help you. That is a security issue. We can not tell you that because you could be someone with a stolen laptop. We have no way of knowing this. You would not want us to explain to someone how to break into your laptop would you?
