The most common reasons for power issues are the battery, power jack and power adapter/cord.
Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.
If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.
The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.
If no change, the power adapter is probably faulty and needs replacement.
