HP 6735s laptop wont power up

Looking for some help please,
When I plug power adapter in there is a blue & yellow ring around it (where the plug fits into the laptop) but goes off after a second or 2, when I press the power button it lights up for about 5 or 6 seconds then goes off, the wireless light also flashes on then off, the blue & yellow ring around power flashes again then nothing! I've tried various power on/off hold for 15 seconds etc etc but still no joy, is it an expensive repair? any advice anyone?
cheers in advance

    Take the battery out and try it without the battery.

    wiggle the cable a bit, could either be a dicky battery connection or a break in the cable.

    If you have one of these or similar check that you have power at the connection from the transformer if you have then the fault is within the laptop (also check the original charger it may be ok!) All the laptops i have had work without the battery being fitted to the laptop it looks more than likely that you may have a damaged power connection on the board could be costly to repair.

    Does the Caps lock/Num lock LEDs flash during start? If so how many times?

    Can you hear fan spin when you attempt start?

    The old trick with dells (when they would not start up!) was to remove the battery and the power cable then hold down the power button for 20 seconds, then plug the power cable back in (leave the battery out for now!) then press the power button.

    If it still does not start then it looks like the power connector in the laptop might be damaged, it's a tricky but replaceable part, if the guy at your local IT shop is good with a soldering Iron...

    Thanks for all the replies:
    Bogtrotter, yeah tried all the wiggling bit before a new power unit was bought.
    malamute, even if I had 1 I wouldn't know what to do with it.
    S0litaire, tried that before,
    thanks again looks like I'll take it to the local repair shop & see if I can get a quote
    cheers all

    Larry22 have a look at this video which will give you an insight into what is required if the power jack is damaged on the board.
