are you using the charger that came with the laptop, if not then it might be a case where the charger you are using doesn't have the volts or amps needed to boot properly. or perhaps you are using the right charger and because it was being used without a battery over time the charger has died, i would recommend getting a battery so you can diagnose if the charger is good enough to recharge the battery whilst the laptop is on.
Edit: you will need a battery anyway simply because of the way laptops are designed.
