Compaq Evo N180 Notebook won't boot from battery.

I can't power the unit on, if its not on the AC adapter.
I checked the battery physically and it reads full on the LED's on the side.
if i pull the AC adapter while the unit is running it shuts down after about 1-2 seconds
The charging light works and it seems as if it would charge.
If i try to power it on without the AC adapter it acts as if it wants to come on for a second, but then it just doesn't.

Any help will really be appreciated.

Have you tried the following? (Caution should be taken. Make sure you backed everything important up)

Turn the computer on, with no battery and no AC
Hold the power on for about 10 sec
Plug the AC adapter in and power on the unit (no battery)
While in operation, insert the battery.
Let it run for a few minutes.
Unplug the AC and see if the computer can switch over to the battery.
Power down the unit.
Power the unit back up with the battery only.

If the unit powers down immediately after yanking the AC again, try to discharge the battery (leave in the computer, off for a few days). Place the battery back in to charge and see if it is infact actually charging.

Lastly try it with another battery. Best to eliminate the easy stuff first.
 
Sounds like it cannot hold a charge anymore. How old is this notebook? My old Gateway notebook's battery lasted about 1.5 years. Did you ever experience your laptops's LCD flash its brightness for no appearent reason? If yes, then your laptop kept switching between the wall and the battery. This happening numerous times will cause yoru battery to die sooner.

Sounds like the circuit board took a dump on your battery.

yup. i agree, get yourself a new battery 80% chance thats it. the other 20% is the charge portion of your mainboard/powerboard within the laptop isnt interfacing with the battery anymore, battery would be cheaper, try to find a used known working one, or try yours (i know this may not be possible) in another machine to see if it still works, you just need to eliminate what isnt the problem, to find the problem, if you can eliminate the battery as bad then you know its the board, if the battery is bad, then, well you know its bad, time to get a new one.
