not charging, no lights on when plugged into charger

You should check the physical integrity of the battery. If your laptop comes with a removable battery, take it out and hold the power button down for about 15 seconds to drain any residual power from the device. Then, with the battery still removed, plug the laptop into a power outlet and try turning it on.

Your charging cable could be loose, unplugged, or damaged. Your charging cable could have a weak connection because it wasn't made by your laptop's manufacturer. Your charging ports could be clogged with dirt or debris that is keeping it from powering up properly. A laptop tune-up and thorough cleaning can help.
