Compaq presario M2000 power cord won't charge my laptop

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.

Post back!

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.

Compaq chargers get heated up a lot when charging. This is a common problem.
Based on the issues you mentioned, unfortunately you would need to get the battery changed.
Regarding the charge cord getting heated up, try keeping it on a concrete/cold surface to lessen the heat. Unfortunately nothing more can be done about it, and as i said compaq chargers do get heated up quickly.
Thanks.

try pressing esc. two times.
Or type admin for username or admin for password. Or try password for password.

Yes the M2000 will support at least an 80GB hard drive.

Could be a bad mother board or a hard drive..see if you can connect the hard drive with a USB on another machine and run a test on it...

The sparking has probably caused your circuit protection inside the AC adapter to turn off the current.
Also, when you are plugging an adapter in,,do not have it plugged into the wall power outlet when plugging into the laptop,,,plug into the laptop first and then plug into the wall.

well, sounds like your power cord took a dump on you check and make sure power cord light is working first i would suggest
takeing up to office depo or computer store or maybe some one you has a lap like your try the power cord on it and see if it boots up that computer or takea differnt power cord and try reboot it they sale altn. power cords for laptops (cheaper in ebay ,ubid or just type in power cords in your search engine ). i hope this helps lala linda
