Hi,

I`ve got hp nx7300 notebook. It does not start.

When I try to run it with connected AC and connected battery nothing happens.
When I try to run it with connected AC and disconnected battery nothing happens.

When I try to run it with disconnected AC and connected battery - power led turns green, charging led blinks 7 times orange, one time green and one time orange and then both (power and charging) leds turns off.

When I try to run it with disconnected AC and disconnected battery nothing happens (well it shouldn`t :) if it worked my notebook would be worth 1000000$).

I`ve tried to remove additional memory and/or disk drive and it didn`t help.
I also tried to run it with another AC but it also didn`t work.

please help,
grzessio

It sounds like your motherboard needs replacing. According to the service manual, this is also suggests the same.

Hopefully your laptop is still under warranty, and HP will replace this for you. It seems link quite a common thing with these.

I agree.  100% it is a faulty motherboard.  I have had this happen to me a couple of times working on clients computers.

if you have a similar laptop around, you can test with a known, fully charged battery.
it may be the charger circuits are failing.
but yes - in most cases it means a new mobo
Agree, when the time you connected AC and disconnected battery with nothing happens, that is cause by the motherboard ......
