Try removing the battery and then plug in the adapter and see if it will run without the battery just using the adapter,if it does not run on just the ac adapter then there could be a problem with the mainboard power supply circiut,or there could be a problem in the charging circiut,again a mainboard problem,one more thing to check would be the output of your adapter make sure the output is what it is on the label of the adapter do this first before you try the other suggestion,hope this helps let us know what you find.
