Ouch!

You may have damaged a power controller chip like the MAX1999 or another.

If you had no problems before replacing the RAM I would say that you shorted a MOSFET and it will need to be replaced.
Or another part. That cannot be diagnosed well via forums.

Typically an 8-pin chip. like 4407/4411/4431 or 48xx series. Cannot tell which one, because I don't know where the screwdriver slipped nor can I see & test the board.

good luck

Compaq M2000 turns on using charged laptop battery but doesn't charge or turn on when using power adaptor, with or without the laptop battery


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.

I have a compaq presario M2000 Notebook. When you plug the charger in the connection sometimes sparks. Any ideas on what the problem may be? Is it the charger or the jack?


you will be able to verify that if you will be able to connect it to another jack, if its still the same thing, its your charger itself

BATTERY IS BAD. CHARGE CORD HEATS UP. REPLACED CORD AND CHARGER LAST YEAR


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.

Burning


The motherboard in your laptop is overheating badly if its melting chargers but more importantly its not charging at times as well. Both symptoms relate to a bad motherboard. Try getting it replaced if you can.

Battery won't charge


Hello,
This is true, you will not be able to charge the battery without the correct charger. For mostly all laptops, when the charger is not maintaining a charge, it is time for a new one. However, it does not have to be the manufacturer's adapter, but I recommend purchasing the battery made for the Compaq Presario M2000 Notebook.
NextTag.com has decent deals on these adapters. http://www.nextag.com/ac-adapter-compaq-presario-m2000/search-html

I hope this helps. Please let me know if you have any other questions.
Thank You, Raph30

Compaq presario M2000 power cord won't charge my laptop


Check that your power adapter is working fine it may be that the power cable is broken somewhere between the adapter and the laptop. You could try another charger / adapter.
