1) AC adapter (Charger) checks to be good?

2) DC Power Jack checks to be good?
(DC_IN.
The jack on the laptop that the AC adapter plugs into)

3) Then the problem is more than likely the Power MOSFET's on the motherboard.
May also include electronic components, that support the P.MOSFET's, too.

Multi-Layer Ceramic Capacitors (MLCC), that are SMD/SMT, just like the Power MOSFET's.
(Surface Mount Device/Surface Mount Technology)

Using the HP Pavilion dv6000, and Pavilion dv9000, series of Notebook PC's for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

For these laptops the Fairchild Semiconductor Industries - FDS6679 - Power MOSFET is used, and the Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET, is used.

Where the DC Power Jack is soldered to the motherboard, is the DC - DC circuit on the motherboard.
If the laptop uses a DC Power Harness, the DC to DC circuit is where the DC Power Harness plugs into the motherboard.

[Some models of laptops have a DC Power Jack, that has a small harness of wires coming off of it.
These wires end in a small male plug connector. The male plug connector plugs into the motherboard.

Will a NVIDIA GeForce gt 610 graphics processor work on a Dell Dimension 2400 PC Desktop


YES, Zian it will work....BUT,....................

1) It is a PCI graphics card, and uses a PCI expansion slot.

http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=2898922&CatId=319

The Dell Dimension 2400 Desktop PC's motherboard, has three long white PCI slots,

http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/techov.htm#1105465

http://www.ebay.com/itm/Dell-Dimension-2400-Desktop-Motherboard-System-Main-Board-F5949-K5148-G1548-/190750417467?pt=Motherboards&hash=item2c699c623b

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

If one of those long white PCI slots is open, you can use a PCI graphics card.

Concerned that the graphics card uses DDR3 graphics memory, and your computer only uses DDR Sdram ram memory?

Don't be.

The graphics card has it's own processor (Graphics Processing Unit), and graphics memory.
It runs independent of the system resources; the Processor and Ram Memory.

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

The concern is the Power Supply.
Original power supply's maximum rated Wattage is either 200 Watts, or 250 Watts.

The above graphics card requires a minimum system requirement/power supply requirement; of 300 Watts.

I would recommend replacing the Power Supply.
(Especially with it's age, if it is still the same one)

ONE thing though..............
Watch the 20-pin ATX main power cable connector, and the wires in it. Be sure they are in the standard place setup.

Check the pinout, and color code of the wires,

1) Dell Dimension 2400 desktop computer, 20-pin ATX main power cable connector pinout,

http://support.dell.com/support/edocs/systems/dim2400/en/sm_en/techov.htm#1105612

2) STANDARD 20-pin ATX main cable connector pinout, and color code of wires; as set by JEDEC,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

[Be aware that the ATX main power cable, and connector, you get with a new power supply; such as the above, will have a 20 =4-pin ATX main power cable connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20plus4

Use the 20-pin connector, tie the 4-pin power cable up out of the way]

For a time period Dell was making the motherboard's main power cable connector - Proprietary.
Meaning they has that motherboard connector wire pinout changed.
Colors of wires were in a different place, than the standard setup by JEDEC.

Orange wires are 3.3 Volts (DC)
Red wires are 5 Volts (DC)
Yellow wires are 12 Volts (DC)
Black wires are Ground wires.

Guess what happens if a 12 Volt Yellow wire, is plugged into where a Black Ground wire is supposed to be?

ZZZZZZzzzzt! Motherboard fries, processor fries, ram memory fries, and graphics card. (If used)

Check the color code of the wires, in the 20-pin ATX main power cable's CONNECTOR, for the Dimension 2400's power supply.

For additional questions please post in a Comment.
