Having problems with your HP Compaq nc6400 Notebook ?

Run normal with the ac adapter without the battery installed. The ac charges the battery when on shutdown. the computer runs normally when using battery power only. Here is the problem: when I connect the ac adaptor with the battery installed the computer does not charge the battery and different messeges start popping up and the the ac and battery Icon on the bottom bar starts switching from one Icon to the other in a flickering motion. what is causing this problem.


Answers :

It sounds like a bad/loose connection does moving the cord affect this?
It could also be a bad power adapter, or a bad mainboard on the laptop.

there is hardly anything we could do about this unless it was a poor connection or a cut cable. if that is not the issue and the same happens with another power supply, then the fault is in the laptop, you could possibly try another battery if you can find another one to try for free.

Lets say if you got a new power adapter and a battery, or tested the machine with another one that is ment for this machine and the same thing happened, then the issue would either be that the plug from the mainboard that goes to the plug that comes on from the power adapter might have broken or become loose from the board.

If that is not the case then its either a software problem on the machine or the mainboard is faulty.


If you are in warranty, I would get it warranty repaired as soon as possible.
