Having turned my laptop off by shuting it down properley, i came to turn it on the next day and no power or boot up; i kept pressing the on button but nothings happened.
The green LCD that on the power pack is visable and i've tryed taking the battery out and then putting it back in but still nothing
When it comes to powering up a system, one of two things could prevent a successful boot.
1. The power supply may be bad
2. The motherboard could have just stopped working.
I have run into problems similar to this with a couple of my desktops. My desktop had a burned out board and while diagnosing I found this out. I eliminated the Power supply by trying it in a different computer and it booted over. Now I know with a laptop it is much more difficult to use this part swapping approach. To me your best course of action would be to have it sent to the manufacturer if it is still under warrenty or have a technician examine it and see what the true problem is.

You didn't post the Make, Model of Laptop or the OS you are using. I'll use a Win 7 solution. Boot the Laptop, open the Control Panel, select Power Options, set to High Performance, select Change Plan Settings, set SLEEP to Never, select Change Advanced Power settings, go through the settings , set SLEEP and Hibernate to Never, Power buttons and Lid to shut down. Always shut down and unplug your laptop when not in use to prevent damage from power surges and possible Fire hazard IF the battery malfunctions. A reboot every day will reset the computer.
This sounds like there is a problem with the battery. Remove the AC mains power and take out the battery from the laptop. Plug AC power back in and try booting the laptop up. If it boots up let it boot into Windows/linux and then shut the computer down as normal. Remove AC power and re-insert the battery. Plug AC back in and power it up, see if it does the same thing. If it does the same thing the battery is faulty. If it boots up with the battery in then there was a glitch.
Forget about calling HP. Unless you recently purchased it, the warranty is already out. There's a known motherboard problem that HP will warranty ONLY if it's a few months old. Check their website or call if you have half a day to waste. Sorry for being negative, but in reality, there's not much hope.
Here's a "fun option" that has worked for some: 1. Power down the laptop. 2. Unplug the AC cord. 3. Remove the battery. 4. Plug the AC cord in again. 5. Push and hold the power on button for 30-40 seconds. 6. IF it boots up, install the battery and you're good to go.
They say this procedure removes static electricity. Actually, it's a sign of the motherboard going out. Days are numbered. Back up all data files when/if you can.
After 8 days of no life at all in the laptop , having 2 computer technicians around saying it was probably the motherboard and just about to send to Sony I pressed the power button and hey presto it worked again..Guess it was just sleeping or hibernating...after all it is spring now....Actually one guy of the many forums I have visited advised just to leave the Laptop alone and perhaps it would mend itself..and hey presto he was right, although having said that I have yet to turn the laptop off and startup again..HMMMMMMM...
