sounds like your DC coonector came loose from the system board.it is a common problem with laptops,

Problem symptoms:

1. Laptop randomly shuts down without any warning.
2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
3. The battery will not get charged.
4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

here is how to repair:

is the battery ok ?

if so check ur ac adapter cables ....

check your DC Jack on the back where electricity is plugged in to the laptop-

Maybe a bad connection.
With Thumb- push the jack to the left and press power button. If this doesn't work, Also try pushing to right, and trying the power button. If you get lights, or it powers on that verifies that you have a DC jack issue.

Do not attempt to use by holding it or using duct tape, get it repaired. If you attempt to use by holding or taping you will further damage the contacts around the jack internally and render the motherboard unrepairable-requiring replacement. This is only a test verification method.

The cost of DC Jack repair/reflow is $50- 100 depending on your area/region.

Try local first before mailing off your laptop!

just google Compaq Presario NX9010 replacement DC Jack

select control panel off computer menu then select performance and maintence icon then select power options then you will see power options properties options tabs.. set properties to suit your needs

this should solve your problem

try and unplug the battery and see what happens when you try to switch it on the external power source.
