if you have a similar laptop around, you can test with a known, fully charged battery.<br />
it may be the charger circuits are failing.<br />
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 ......

When I try to run it with connected AC and disconnected battery nothing happens.<br />
<br />
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.<br />
<br />
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$).<br />
<br />
I`ve tried to remove additional memory and/or disk drive and it didn`t help.<br />
I also tried to run it with another AC but it also didn`t work.<br />
<br />
please help,<br />

How to make hp nx7300 start?

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
