Having problems with your Compaq Presario M2000 Notebook ?

I have a compaq laptop its dead, i want the mother board diagram


Answers :

Motherboard diagram? Is this to trace where the power comes in to the motherboard?

The Compaq Presario M2000 Series Notebook PC's, use a separate Power Board. A small, rectangular circuit board, that plugs into the mainboard. (Motherboard)

This circuit board can fail. The DC Power Jack is soldered right to the Power Board.
(DC Power Jack is also referred to as DC-IN jack. The jack that your AC adapter {Charger} plug, plugs into.

You can replace this Power Board. (Diagnoses should include a continuity test, to see if the Power Board is bad, first)

There is a sensor module on the motherboard also. Senses when the battery needs charging, and differs a trickle charge to the battery, when the AC adapter is plugged in. Also senses when the laptop is just using battery power, and not the AC adapter.

Replacement is accomplished by replacing the motherboard. (Unless you have a BGA Reflow machine, proper tools, an extensive background in this area, and that sensor module chip)

If you're going to replace the motherboard know this;

1) The heading above for the problem - Compaq Presario M2000 PC Notebook, just states a series of Compaq laptops.
The Compaq Presario M2000 Series.

There are many models within the M2000 Series. The exact model number is on the bottom of the laptop, in a white Service Tag.

The M2000 Series has different processors offered. The processors are of the Intel line, and processors supported are Intel Pentium M, and Intel Celeron M.

Intel Pentium M:
1) Pentium M 715A (1.5GHz)
2) Pentium M 715 (1.5GHz)
3) Pentium M 725 (1.6GHz)
4) Pentium M 735 (1.7GHz)
5) Pentium M 745 (1.8GHz)
All of the above processors have a 400MHz FSB.

Intel Celeron M:
1) Celeron M 320 (1.3GHz)
2) Celeron M 350 (1.3GHz)
3) Celeron M 360 (1.4GHz)
4) Celeron M 370 (1.5GHz)
5) Celeron M380 (1.6GHz)

All of the above processors have a 400MHz FSB.
All of the above Pentium M, and Celeron M processors, use the Socket 479 processor socket.

http://en.wikipedia.org/wiki/List_of_Intel_Celeron_microprocessors#Celeron_M

[You can type - List of Pentium M microprocessors - in the search bar to the left of the page, also]

There are also different motherboard chipsets used.
(Northbridge/Southbridge chipset)

1) Intel 82852
2) Intel 82855
The 852GM is used for Celeron M processors
The 855GM is used for Pentium M processors.

Also look for the HP ID number on the motherboard.
Some examples are 373522-001, 431092-001, 381062-001.
(Plus DA0CT2MB6B1 Rev: B, DA0CT1MB613 REV:1, and DA0CT1MB6H5 REV:H)

You need the Correct motherboard.

The Northbridge chip is located under the processor, in a heatsink that is mounted diagonally, to the processor.
If memory serves, the Southbridge chip is to the right of the Northbridge chip.
[Processor at the top, Northbridge chip below it, Southbridge chip to the right)

That's the closest I can get you to a motherboard diagram. If the laptop was operational, you could download, (Free), CPU-Z, and see what exact hardware is installed.

What you may be needing is a Flow Chart. This way you can do a diagnoses step by step, to find the problem.

Check with Foner Books,

http://www.fonerbooks.com/workbook.htm

If you wish to disassemble your laptop, to see if there are obvious signs of failure,

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=500512&

Go to the 7th file down.
HP Pavilion ze2000 Notebook PC, Compaq Presario M2000 Notebook PC - Maintenance and Service Guide (4.75M)
(It's a Service Manual)

Left-click right on the file name.
You may not see anything happening after you click on the file name, for up to 30 seconds. It is downloading in the background.

Advise let the file download all the way, before looking through it. You may break the download connection, if you don't.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.

To save this file to your computer, left-click on the Floppy Disk icon, in the top header of the file.
This is the second icon from the left side.

If you hover your mouse cursor over the Floppy Disk icon, it will briefly reveal -
'Click to save this file to your computer or another location'

After you click on the Floppy Disk icon a small window will come up.
Save a copy...

At he bottom in the File name box, is the name of the file. Write it down.
Go to the bottom right of the window, and left-click on
Save.

You should work on a table, and wear an ESD wrist s-trap. (Electro Static Discharge) Connect the alligator clip to a good ground. (Average cost is $6, and available in a multitude of places)

Your body carries Static electricity. Static will fry out computer components.
The ESD wrist s-trap relieves your body of Static.

Your problem may be a Power On switch, or the Power Board, or something simple to replace. It would be a shame to fry out the laptop, by not wearing an antistatic device.
Check the manual,it is there.
In case, you don't have the manual,then you can downalod it from the link below
