There could be a problem with the battery. A fast check to determine whether you have a problem with the power
adapter, power cord or the laptop's battery is to turn off the laptop,
remove the battery, connect the power adapter, turn on the laptop &
see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.
If this did not work, try also disassembling the laptop & make sure that all main components are seated properly. Also make sure that all ribbon cables interconnecting the various components of the laptop are tightly connected.

SOURCE: I bought a new charger
The first thing to do is check that the charger is putting out the correct voltage, which should be ~18 volt. Then try to start it without the battery.
If your voltage is OK and the battery out makes no difference, then I would suspect that you have a motherboard problem that must be fixed. If the computer starts up if you wiggle the DC plug where it goes into the computer, then it's the DC jack that is looks and must be re-soldered.
