If your battery is dead, try plugging your laptop into the charger and see if it will power on while it is connected.

If your battery will not charge, you may need to go buy a new battery.

If you replace the battery and your laptop will still not turn on then it is possible that it is not charging because the charger itself is defected. If this is the case, you will need to go purchase a new charger.
