How do i turn off the scroll function on the mouse pad ? (compaq presario m2000)

1) The AC adapter should ALWAYS be plugged into the laptop FIRST, then plugged into AC power. If not, this could create a voltage spike.

2) Let's look at the DC Power Jack, for the Compaq Presario M2000 series of Notebook PC's,

http://www.notebookparts.com/products/description.php?II=9741

The DC Power Jack is mounted to a removable circuit board.
Enlarging the view of the jack, shows us there is an Inductor.

The small 'can' standing up on the power board. This chipset could have gone south. (Bad)

How to know? Replace it, or dig out your dual trace oscilloscope. See if the Inductor works.

Could also just be cracked solder joints, of the DC Power Jack, TO that small circuit board. Solution would be to resolder it/them.

[ I WOULD however, search for a BETTER price, than listed in the link above, IF available ]

DC Power Jack is in good shape, soldered tight to the motherboard, and ruled out as the problem?
(Since you know the AC adapter is good)

Then the problem would be the Inductor on that power board, or power correcting chipset.

What one is it? Dunno.
DO KNOW is has J leads on the bottom.
CAN give examples, and perhaps you can identify using them.

The scroll pad on the touch pad needs a particular driver Synaptics Pointing Device Driver. This will actually run at the startup after installed which will activate the functionality of scroll on the touch pad. You can also actually turn this function on and off so this is a friendly user.
If you do not have that driver that comes with your laptop you can go here:

Good day.

my mouse pad on my compaq presario m2000 wont work

Update your drivers, first:
http://www.fixya.com/support/t1381478-webcam_not_working

Then go to Start: Control Panels: Mouse and double-check your configuration for each button.

almost certainly this means that the drivers for the touchpad have reverted to the windows generic drivers. Try the driver from Compaq here. Sadly, without knowing the OS and exact model number of the laptop I can't be more specific on the link than that. The exact model of the laptop is usually printed on a sticker on the bottom.

check the sound card drive
see if u have installed the same driver required by the laptop

go to mouse setting under control panel.
You will find a place to turn it off.

hold down the fn key and press the scroll button.
