You need to check the adaptor first

check voltage at the jack plug - centre to outer pins should be as written as output on the adaptor typically 19v DC on modern laptops. This proves output from adaptor is OK

next check the DC jack socket in the laptop is not loose or centre pin broken. these sockets are a common failure point whn they lose their connection to the motherboard.

after that its more serious as power board / motherboard in laptop could be dead.

The socket on the laptop seems fine mare. Is there any other way to determine if the laptop is dead or its just a power issue?

The charger is still the one i got with it and it worked before.

Green LED maybe lit but cables to the jack plug get broken at plug or block ends so best check is with a meter or by using on another compatible machine. Sockets can get "dry joints" where fasten to board.

If the adaptor and lead are OK its a laptop strip down job.

If as you said you bought and fitted a new battery (they always come with a small amount of charge) and you were still unable to get even a short spark of life from the laptop, then that would rule out power supply and connector issues

From there it gets very complicated to make further diagnostics without specialist equipment and ready access to spare parts

I take it you tried it with the battery off.

Maybe try and move the jack gently to see if you get any type of connection if so it could be a problem with M/board connector.

Ok i done what you said Buteman i moved it about and it did power on, but it didnt stay on, so it must be a lose m/board connector is there anyway i can fix this myself without leaving it in to get fixed?

That 'wiggle' could be a loose connection on the mobo, but could also be in the plug on the end of the adaptor lead. Not too easy to prove which. Resoldering a mobo pwr socket is not for the faint hearted - it usually entails a complete strip of the laptop, so I'd try to check the adaptor plug first. Some laptops have the socket connected to a short harness which plugs into another socket on the mobo. These are much easier to change (no soldering), but still entail a complete strip. Not sure what your laptop has, sorry.

If they are shown in FB's link, I'd think twice about attempting it (without knowing your abilities). Having changed a few (and with a background working in a Telephone repeater station repairing amplifiers), it's not that easy.
