Ive worked on a friends G7000 series laptop, since it had the same symptoms you have with yours.
I tested it on my own(identical) working charger/PSU and still no charging.
After taking the motherboard out, i traced the fault to a short circuit FET (field effect transistor) with the PCB reference of PQ1, located right next to the connector for the DC power jack loom.(short from gate to source) The FET is made by Fairchild Semiconductors and its part number is FDS6675BZ. Being in the UK, i ordered the part from www.farnell.co.uk at a cost of 56pence. After changing this FET(which is there to control power) the laptop is working.
If you are not good with very intricate surface mount soldering, then i suggest you buy the component, take the motherboard out of the laptop(not too hard) and take them both down your local TV repair shop for them to check and change it(tell them the board reference PQ1).. shouldnt cost more than £20 or so been as they dont have to fault find.

Have you tried another cord/charger with the EXACT same power specs? Has the AC jack, in the laptop, been damaged due to pulling on the cord/charger? Have you tried with and without the battery? Does it power with the battery? Has there been ANY damage? If you remove the battery what does it do? Describe what happens, without battery, when you push the on/off button? Anything? Led blink? Fan spins?
The laptop is either in sleep mode or the battery is low. If the laptop doesn't want to wake up, try unplugging the charger cord, then removing the battery (usually by sliding something on the bottom of the laptop to unhook it). Wait for 30 seconds then put the battery back in, plug in the charger and press the power button.
This could be caused by several things, but try the obvious first. I just bought a brand new power supply, and in less than a week the customer called and said it stopped working. I suggested she take the cord from the old charger and try it - it worked - the brand new cord lasted less than a week. The other thing that could cause this is a bad connection on the end of the power supply, going into the computer. It could even be a bad power supply.The last thing I can think of is a bad battery that won't hold a charge.
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.
Sounds like the battery is not being charged properly. With a voltmeter, check for voltage at the output of the charger that plugs into the computer. It should read several volts higher than the battery voltage rating. It is common for one of the wires to break just inside the plug. Radio Shack stores have a plug and cord that fits the computer, but the new wiring must be spliced into the original cord (with the correct polarity). Replacement cost for a new charger is quite high! Good luck!
Well, smoke is never a good sign.
Tell me, the 'something banged' thing, could that have been the laptop was being moved and the power cord was jerked at the connection to the laptop?
These are very prone to have problems with the ac jack coming loose from the motherboard (I have 3 in the shop right now with the same problem)
If you can, check and see if it's getting juice to the battery when plugged in using a multimeter.
