This is a known issue with the nc6xxx series. The problem is with the Maxim chip that needs to be resoldered. Take a look at this repair manual, it has all the instructions you'll need to do a Maxim chip resolder http://ebooksandtutorials.com/toshiba-m35-hp-nc6000-laptop-repair-manual

Take a look at the back of the laptop. Is the gold power pin still there or is it now stuck in in the end of the power brick cord?

HP actually extended the wty on these machines because of the
power pin issues. If the power pin is missing you will need to have the machine serviced. Out of wty, replacement power pins are easy to solder on the board if this is the issue.

If your pin is still there... Your AC cord or power brick may be the next things to check. Connecting them to a meter will tell you if there is power. Try moving the cords to check for shorts in the wires.

If your AC cord and brick are good, try pulling the battery. Your laptop can run off AC only. Batteries with bad cells can sometimes prevent the machine from powering up.

If its still not powering up after all of that, there may be an issue with the motherboard in the machine.

I suggest that you take it back. You should be able to swap it for a replacement.

Power drain would be a better solution in this case.
1.first shut down the comp
2.unplug the charger
3. remove the battery
and after press and hold the power button for 60 seconds without any charger and the battery.After the 60 seconds replug the battery and the charger and turn the computer

As for the power-on password, you'll need to find a way to jump the CMOS battery, or invest in a new laptop.
Once you lock out the BIOS, the computer will not run any bit of hardware, unless you jump the battery and reset to factory settings.
If you somehow manage to do that, next thing you'll need to do is find a program that will boot from a CD to remove the password on your account.
I recommend using the Hirens BootCD to do this, as it also has many utilities that will help maintain your computer.

To kickstart the wireless and make it work again on the nc6120's.

Turn on the computer and hit F10 to go into the BIOS.
Go up under File and choose Restore Defaults.

Save your changes and reboot your OS.
If your using Windows, you should be able to pick a wireless network now.

If you previously had a WEP or WPA pw key set, you may have to re-enter
it again as it was cleared out during the reset.

Test the charger, it may be fried. It's also possible that you need to replace the jack inside the laptop.
