M2000 battery and very slow

If there is no power going to the laptop then disconnect battery and hold the reset button in for 30 seconds, then try it again. Sometimes the memory can be damaged which can cause the laptop not to boot..?

This model Compaq laptop does not have any SATA connections/ports.
This WEB site shows the specs for this laptop.

The processor is designed to gear down when you switch to battery mode to conserve power, this way the rechargeable battery last another 30% longer at least.

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.

Because the new battery isn't fit your laptop, just find the Compaq Presario M2000 battery replacement.

If the battery is over a year old then it could be dead.Anything over two years I would bet on it. Usually the power bricks are very reliable. To check it you just need to put a power meter on it and check the voltage against what is printed on the brick. It should be slightly higher.

Without a meter it is pretty hard to check. You should get some indication that it is plugged in. It may have a power light on the brick or the laptop that shows it on even if it wont charge.

Start / control panel / power.

Then you will see a list of options, 'check' the box which says 'always show battery in taskbar'. Or words to that effect.

That'll fix it.

Erik.

Check the Power settings in control panel.

Use msconfig to clear the unwanted programs which are loading during startup. This should make the laptop faster.

Let me know what happens.
