Check your charger first. If it has the right voltage, you might want to see if internal connections are all in place and that the power jack is firmly in place.
Let me hear of your results.
(it is not recommended but a common practice to suck on the power jack (if under 12 V) to see if it has current if you have no measuring tool. f it does, you should feel a tingling sensation on you tongue, much like as with licking a battery just a lot stronger depending on voltage)
