820-3209 keeps chiming

Hi, ive got an 820-3209 that keeps chiming repeatedly even with everything disconnected , there is no signs of spillage anywhere the board is as clean as a whistle, so im pretty stuck as to where to start with this one , so any help would be appreciated
 
Nope , starts chiming as soon as i plug in the power supply, was wondering wether to relow smc incase of bad connection ?
 
as far as i know i did, had to look it up on how to do it but apparently hold you finger on the power button for approx 20secs but didnt get that far, laptop started up within 3 - 4 secs

You must press power button (in the first instance), then connect charger and maintain button pressed 5-10s.
Did you do it like that?
