Take the battery out, plug in the charger and see if the laptop works.
If it works, the battery may be the problem.
Check the AC AdapterCheck to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop.
Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity.
If that light isn't on, try a different outlet.
Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it.
If it still does not light up, your adapter could need replacing.
Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.Remove the BatterySometimes it's as simple as a seated battery.
Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection.
Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement.
